M12 Connector

An M12 connector is a circular connector commonly used in industrial automation applications such as actuators, sensors, Fieldbus networks, industrial ethernets, and so on. This standardized connector is essential to maintaining good operational conditions within industrial control systems.

How does an M12 connector work?

Commonly used in washdown and corrosive environments, the M12 cable is designed to have a 12-mm locking thread, which provides a firm connection to sustain stable network operating or communication systems. These connectors, equipped with gold-plated terminals to provide stable performance, are available as a 3- or 4-pin M12 connector, a 5-pin M12 connector, an 8-pin M12 connector, and a 12-pin M12 connector. The M12 connector cable is built for uninterrupted service as it may be subject to extreme environmental conditions. The cables may be exposed to all forms of intense weather, so they are wrapped in premium thermoplastic polyurethane (TPU) material with a bend-resistant rubber covering throughout the entire cable length. In addition, it is waterproofed with tight O-ring seals to prevent water or moisture seepage.

The M12 connector coding options

Them12 socket comes in a variety of coding options, and each socket is designed to be used for specific purposes. With this coding system, a coded cable can be paired with the correct connector. For instance, the coded connector helps prevent an AC power cable from being mistakenly hooked up to an M12 ethernet cable. The m12 connector code is as follows: the M12 a-coded connector is used for sensors, 1GB ethernet, and DC power; the b-coded M12 connector is for network connections; c code is for AC power; the M12 d-coded connector is for 100MB ethernet; and the M12 x coded connector is for 100 GB ethernet applications. By using this integral component, electrical systems can perform efficiently and maintain good terminal connections.
