FAQ

1.What is the difference between M12 connector coding？

• A-coded mostly used in sensors, actuators, motors, and most other standard devices. it usually between 2 and 12 pins.
• B-coded mostly used in network cables for Fieldbus connections, includes systems that operate with Profibus. it typically have between 3 and 5 pins.
• C-coded primarily used with AC sensors and actuators, and also have a dual keyway for added security. it have between 3 and 6 pins.
• D-coded typically used in network cables for Ethernet and ProfiNet systems. it transfer data up to 100 Mb and typically provides 3 to 5 pins.
• S-coded are for ac power application.
• T-coded are for dc power application.
• X-coded can transfer large amounts of data up to 10Gb at high speeds, it will always have 8 pins.

 

 

2. What is the application prospect of M12 connector

M12 connectors will be more suitable for the Industrial Internet of Things (IIoT).

The IIoT is a real-time data connection, driven by processing and transmitting data at faster speeds, on progressively smarter and smaller machines. The value of the IIoT goes beyond data collection and transmission, it benefits including but not limited to the ability to identify disruptions, discovering unused capacity, reducing maintenance costs and downtime, improving safety,  and maximizing overall equipment effectiveness.

M12 connectors’ advantages in the speed, reliability, and ruggedness, etc perfect match the smart factories’ demand.

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.

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 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.
