M12 circular connector and cable

M12 is a kind of sensor connector

M12 is a kind of sensor connector

 

According to the EIA/TIA standard, the M12 connector corresponds to the transmission technical conditions of the category 5 modular socket (RJ45). The use of D code can prevent it from the wrong connection with A code (used for sensor and brake wiring) and B code (used for some field buses).

 

There was no type of M12 connector that could be used for printed circuit boards before, until the M12 connector with surface mount termination was born. Surface mount terminations contribute to the miniaturization of field devices. The sturdy pins allow it to pass through batch packaging and the corresponding feeding process using a vibrating bowl. Another packaging method is tape and reel packaging.

The basic modular design concept creates connectors with various installation heights and different pin types. Based on user needs, the termination methods provided include surface mount, crimping or through-hole reflow technology, of which surface mount technology is the standard. The black insulator of the connector is made of high-temperature plastic, so there is no problem in all conventional surface mount soldering procedures. In the past, the controller in the switchgear used the I/O card to drive the field devices; now, in the ultra-distributed industrial automation system, field brakes and sensors are often connected to a passive or fieldbus performance I/O box.

In order to provide solutions for multiple applications at the lowest cost, specific field devices require high-level modular flexible connector solutions. To this end, the various printed circuit board types of M12 connectors are supplemented by a cable system. Different model shapes, pin numbers, cable quality and length help to achieve cost-effective and customized automation solutions.

About M12 connector development overview

Since its inception in 1985, the M12 connector has grown into the interconnection system of choice in the industrial automation field. This kind of sturdy and durable connector can achieve reliable connection in the harshest environment, thus bringing an innovation to the connection technology in the field of industrial automation.

The M12 connector is a circular connector with a 12 mm locking thread, and generally has an IP protection level to prevent liquid and solid intrusion. M12 connectors are ideal for sensors, actuators, industrial Ethernet and fieldbus devices, and are mainly used in industrial automation and corrosive environments.

Before the M12 connector was developed, engineers either had to directly pull the cable, or had to repeatedly replace the connector due to poor use conditions. The initially released M12 connectors are 3-pin and 4-pin models. Although they are inferior to its predecessor, the RK30 connector, in terms of the maximum current allowed to flow, it can provide IP67 protection. The 4-pin M12 connector allows a single system to incorporate more advanced sensors and actuators. Nowadays, such sturdy and durable connectors are divided into 3-pin, 4-pin, 5-pin, 8-pin and 12-pin configurations, and various new locking methods such as bayonet and push-pull are continuously developed.

In addition to factory automation, M12 connectors and M12 cable assemblies can also be used in measurement and control, communications, transportation, robotics, agriculture, and alternative energy fields. The correct selection of the number of pins depends on the specific application requirements-3-pin and 4-pin models are used for sensor and power applications; 4-pin and 8-pin models are used for Ethernet and PROFINET; DeviceNet and CANbus generally use 4-pin and 5-pin M12 Connector; 12-pin models are usually used for various signal applications.

In addition to the different number of pins, the M12 connector also uses a variety of key positions to prevent incorrect mating. The most commonly used encoding types and their uses are listed below:

l A code: sensor, direct current, 1G Ethernet

l B code: PROFIBUS

l C code: alternating current

l D code: 100M Ethernet

l X coding: 10G Ethernet

l S code: alternating current (to be replaced with C code power components)

l T code: direct current (a code power component will be replaced soon)

The most popular M12 encoding types are A encoding, B encoding, D encoding and X encoding. A code, B code and X code are some of the M12 connectors that have been developed the earliest and have the longest time to market. In the field of high-speed industrial Ethernet, the demand for X-coded connectors continues to grow, and will eventually replace A-code and D-code components in Ethernet applications. The latest M12 code types currently under development are K code for AC power and L code for PROFINET DC power.

What is M12 circular connector?

M12 circular connectors are manufactured in accordance with international standards. The number of pins is 2 pins, 3 pins, 4 pins, 5 pins, 6 pins, 8 pins, 12 pins, 17 pins, etc. According to international standards, it is used in various fields to connect one of the main electronic components of the signal.

M12 connector pin

M12 circular connector, a high-level connector that meets EU standards. Has high signal integrity and excellent performance.

M12 circular connector, combined with power cord and data line, is characterized by reducing the footprint and reducing installation and cost. It is suitable for process automatic control and industrial applications, automation equipment, electronic equipment, electronic instrumentation, sensors, commercial transportation, and aviation applications.

The M12 connector is a motor system, which can provide a detachable interface to connect two secondary electronic systems, and will not produce unacceptable effects on the operation of the system. The key words in the definition are “motor system”, “separable” and “unacceptable role”. The connector is a motor system because it is electrically connected by mechanical methods. As will be discussed, the deflection of the mechanical spring creates a force between the two mating parts, which causes metallic contact between the mating surfaces of the interface. The reason why the connector is used in the first place is the separability of the mating interface. The need for separability has many reasons. It makes it possible to manufacture parts or sub-systems independently and the final assembly can be carried out in one main place. Separability can also make the maintenance or upgrade of parts or subsystems without modifying the entire system. Another reason why separability is applied is portability and the expansion of supporting peripherals.

On the other hand, the separability in the definition introduces an additional interface between subsystems. This interface cannot introduce any “unacceptable effects”, especially the characteristics of the system cannot be affected by telecommunications. These effects include such as Unacceptable distortion and signal degradation between systems, or power loss by adding M12 connectors, power loss calculated in millivolts, will become the main functional design standard, so the power demand of the motherboard will also Increase.

The requirement of separability and the limit of “unacceptability” are determined by the application of the connector. The detachability includes the number of mating cycles. The mating cycle refers to the force that the connector must provide without affecting its performance and the force necessary for mating with another connector. Typical mating cycle requirements range from tens of cycles for internal connectors to thousands of cycles for peripheral devices, such as PCMCTA type connectors. As the number of circuits or functions and the interconnection of connectors increase, the need for matching strength becomes more important. In order to provide more functionality, the position of the terminals on the connector must also be increased, which results in a higher connector mating force. Depending on the use and function of the connector, the number of terminals ranges from tens to thousands.

Sensor M12 4pin Male Female Receptacle

The sensor M12 4in receptacle is used in industrial electrical and aviation projects. Its main function is to ensure reliable connections between electrical appliances and signal transmission, it is a very important part of the project.

Advantages of using sensor M12 4-pin socket

  1. Improve product coordination performance: When technical engineers are developing new product integration or design schemes, the sensor M12 4-pin socket is used as the component to form the system software, which can give the product a very good coordination ability.
  2. Improve productivity: The application of circular connectors can help reduce the installation steps of electronic device products, which not only improves the efficiency of production and manufacturing for the company, but also reduces labor costs.
  3. Convenient maintenance: If the connected electronic components are invalid, if the circular sensor M12 4-pin socket is installed, it is very convenient to replace the invalid components, reducing the inconvenience of maintenance in the middle and later stages.
  4. Convenient upgrade: The current technology development trend is to connect based on the sensor M12 4-pin socket. When the product is upgraded, it can be very convenient to replace the old product with a stronger product.

Note when using sensor M12 4-pin socket

Welding is a very important part. If the welding is not in place, it may cause the net weight of the sensor M12 socket to be welded to be different from that of another aviation plug, or the distance is too large. As a result, during the welding process, the pins of a certain welding piece are deformed due to the different temperature levels, making the welding between the electronic devices unrealistic. This type of situation is sometimes difficult to be found during inspection.
When used by customers, due to the continuous load operation of machinery and equipment, or the application of machinery and equipment in the natural environment is more extreme, the temperature changes strongly. Long-term overload operation under high temperature conditions makes the temperature of the soldering point too high, and the solder wire deforms and melts, which is very easy to cause short-circuit failure.

A more common solution to this problem is to increase the frequency of the centrifugal fan of the reflow oven appropriately to accelerate the welding rate of the sensor M12 4-pin socket, thereby reducing the probability of pin deformation of the sensor M12 4-pin socket. However, you must pay attention to the temperature control when using this method, and always pay attention to the temperature change. It is not necessary to let the temperature of the sensor M12 4-pin socket rise too fast. The maximum value should be flexibly adjusted according to the welding equipment and the size of the pins.

I believe everyone must have a deeper understanding of the sensor M12 4-pin socket now.

M12 Round Metal Connector

First, it is necessary to clarify the main purpose of the connector, because there are many specifications and models of the M12 connector, different types of connectors are used in different situations. It can also be customized according to the customer’s use occasion, according to the target, frequency, output The power and application scenarios are different, and there are various M12 circular metal connectors in different ways.

In particular, the M12 circular metal connector is not limited to current. In today’s rapid development of optoelectronics technology, in the optical fiber system software, the medium for transmitting data signals is light, and laminated glass and plastic replace the general Power transmission lines in power circuits, but connectors are also used in optical signal paths, and their functions are the same as power circuit connectors.

Secondly, the electrical equipment characteristics of the high-current M12 circular metal connectors should be considered: current, working voltage, and resistors should be considered comprehensively. Generally, customers only know how many square meters of cable they choose and how much current they are. After application, they find that the current is low and the item burned. Why? Because the output power is very large, it is not positively related to the current. Here also consider the instantaneous current, the working voltage is also critical.

The technical engineer calculated the current, working voltage, resistor and output power of the connector accurately. There is no problem with the left and right calculations. They did not remember that the motor starting current is very large, and must remember the high current M12 circular metal connection The main parameters of the device should be improved to ensure safety. To complete the waterproof function of the M12 circular metal connector, it is necessary to ensure that the docking page and each sub-page can complete the sealing function.

The structure of the M12 circular metal connector is divided into two parts: a power plug and a power socket. In general applications, the power socket is installed on the experimental instrument and fixed according to the installation flange. The power plug is constructed as a cable and can be connected to the power socket. Complete the transfer function. The butt end is equipped with a rectangular silicone ring, both sides are set in the installation threaded holes, and the tail is made of epoxy resin for sealing.

When installing, use 2 mounting screws, and choose the post-board mounting method. The power socket is fixed on the mounting plate. The square sealing ring on the power socket is reduced when the mounting screws are tightened, which is airtight and waterproof. The other end of the M12 round metal connector should be fixed with a waterproof wire clip. The power plug of the M12 round metal connector is installed in the waterproof wire clip. The mounting screws on both sides of the wire clip cross the power plug of the connector and are in the waterproof wire clip. A large-volume sealing ring is set up at the butt end.

When the power plug is docked with the power socket, the mounting screws on both sides of the cord clamp and the threads of the hexagonal mounting screws on the control panel are engaged. With the effect of the mounting screws, the power plug of the connector and the power socket are inserted; in addition, waterproof The square sealing ring of the docking end of the wire clip suffers from the shrinkage of the installation control panel, which completes the sealing and waterproof effect of the docking page of the M12 circular metal connector.

I believe everyone must have a deeper understanding of M12 round metal connectors.

Install Front Mount M12 PG9 Socket

The install front mount M12 PG9 socket is suitable for application in generally no more than 85 degrees Celsius. If the temperature of the lighter is thousands of degrees, the conventional aviation connector must not be able to bear it.

However, the install front mount M12 PG9 socket uses the thermoplastic crown polycarbonate PC, which is a low-voltage aviation plug. Its impact resistance and flexibility can be used in a long-term application in a natural environment of -60 to 120 degrees. Between 130-140 degree. Fireproof materials increase the service life of aviation plugs to a certain level, improve the load working capacity and avoid electrical fires caused by poor contact, and consider the safety of home furnishings and work.

In the case of installing front mount M12 PG9 socket, the pins can only be extended with a certain amount of force, and it is easier to pull out. It can be seen that the insertion of the connector is wider than the extraction. Therefore, the mutual influence of the two forces of insertion and extraction can easily cause damage to the connector. If you want to reduce damage, there are many ways to try:

1. It can increase the strength of the gold-plated layer on the touch surface, so as to reduce friction reasonably.
2. The surface can be electroplated with nickel and then plated with gold, which will cause less friction than immediately plating on copper. The thicker the nickel layer, the stronger the wear resistance of the gold-plated layer.
3. The smoother the surface, that is, the lower the surface roughness, the smaller the sliding friction.
4. Pay attention to the maintenance of the connector during the normal application of the connector to prevent the connector from being damaged by human factors.

Materials Regulations for front mount M12 PG9 socket

When the power plug is plugged in, and when the power switch of the aviation plug is turned on, fire occurs, that is, the ignition condition commonly referred to by everyone, which is called arc flash in the technical profession. The embrittlement of install front mount M12 PG9 socket, the momentary short-circuit fault, and the reduction of grounding resistance are all the key reasons for the fire accident of household appliances.

Therefore, from the perspective of the country’s formulation of specifications for raw materials and product design, relative regulations must be met for the raw materials of each position of the product. The specification stipulates that the flame retardation of the plastic material in direct contact with the conductive member is higher than that of the plastic material of front mount M12 PG9 socket. Only in this way can it be ensured that the commodity raw materials can withstand ignition and arc flash.

I believe everyone must have a deeper understanding of front mount M12 PG9 socket. Renhotec Group specializes in aviation plugs, waterproof connectors, sensor connectors, cable connectors, sockets with wires, automotive wiring harnesses, round Connectors, waterproof sockets, water level and temperature sensors, etc., the same day delivery, quality is guaranteed, please call for consultation and cooperation. http: www.renhotecpro.com.
