If you go to a factory that uses any sorts of motors or robotics, or an automation exhibition, or pretty much anywhere that has machines being controlled electronically, you are almost certain to see M series connectors.
The M stands for Metric, and signifies the size of the thread. The most commonly used examples are M8 and M12 connectors (according to IEC61076-2-101 standard).
Through our global network of partners, R.E.C. is able to source all types of M series connectors, in sizes M5, M8, M10.5, M12 and M23.
