Both M8 connectors and M12 connectors are common connector types, and they differ in appearance size, number of pins, electrical performance, etc.
The outer diameter of the M8 connector is 8mm, and both the plug and the socket have 2 to 6 pins, and 3 or 4 pins are commonly used. M8 connectors are usually used to transmit low-voltage, low-power control signals and are suitable for compact application scenarios.
The outer diameter of the M12 connector is 12mm. Both the plug and the socket have 2 to 12 pins, and 4, 5, and 8 pins are commonly used. M12 connectors can be used to transmit power, control signals, analog signals, and digital signals such as Ethernet.
Therefore, M12 connectors are generally more suitable for occasions that need to transmit more types of signals and higher signal transmission requirements than M8 connectors, while M8 connectors are suitable for occasions that need to transmit low-voltage, low-power control signals.
In short, the choice of M8 connector or M12 connector needs to be determined according to specific application requirements.
