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 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 Military/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.
