M8 Miniature Industrial Connector — Panel Mount Socket, 3-Pin

Specifications

Description

The 3-pin M8 socket is the simplest and most widely deployed M8 configuration, handling the classic PNP sensor wiring: brown (+), blue (-), black (signal). This panel-mount socket variant serves as the device-side interface on micro-sensors, where space constraints demand the smallest possible connector. The 3-pin keyed design prevents incorrect orientation and supports quick-connect tool-free installation in high-density sensor arrays.

Application

DC 3-wire PNP proximity sensors (inductive, capacitive), NPN photoelectric sensors, simple limit switches, magnetic reed sensors on pneumatic cylinders (SMC D-M9 series), compact temperature probes. The 3-pin M8 is the universal connector for simple discrete sensors where power + single output signal suffices — found in millions of installations across automotive assembly lines, packaging machinery, and conveyor systems worldwide.
