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.
