What is an M18 connector for?

An M18 connector is the metric circular that matches the body of the common 18 millimetre proximity switch, so the sensor and its lead share one thread. It carries the few poles a switch needs at higher current than an M12 and seals to IP67 mated. It sits between M12 and M23 in the family and is ordered by pole count, gender and mounting.

Defined by The IEC 61076-2 series, which specifies the metric circular connector interfaces, published by IEC.
