The m series connectors M12 connector is industrial connector types, now recommended in almost all fieldbus specifications and is subject to IP67 protection levels according to IEC 61076-2-101/104, traditionally used as a sensor and brake in connection automation technology.
Previously, there were no m12 connector types available for printed circuit boards until the surface mount M12 connector was introduced. The surface mount technology contributes to the miniaturization of field devices. The robust pins enable it to be fed through bulk packaging and corresponding use of a vibration bowl. Another packaging option is tape and reel packaging.
The basic modular design concept allows for connectors with different installation heights and different pin configurations. Depending on the user’s requirements, available termination methods include surface mount, press-in, or wave soldering techniques, with surface mount technology being the standard. The black insulation body of the connector is made of high-temperature plastic, so there are no issues in all standard surface mount soldering processes.
In the past, controllers in control cabinets drove field devices via I/O cards; nowadays, industrial automation tends to be more decentralized, with field actuators and sensors often connected to a passive or bus-capable I/O box. To provide cost-effective solutions for various applications, specific field devices require highly modular and flexible connector solutions. Therefore, the various m12 connector types for printed circuit boards are supplemented by cable systems. Different models, shapes, pin counts, cable qualities, and lengths contribute to achieving cost-effectiveness and customized automation solutions.
