IP67 Proximity Switch Sensor Autonics PR18-5DP IEC Standard 12VDC–24VDC
PR18-5DP Autonics Inductive Proximity Switch — M18 PNP NO Sensor (Factory Sealed)
The PR18-5DP Autonics Proximity Switch is a high-reliability cylindrical inductive proximity sensor designed for precise, non-contact detection of metal objects in industrial automation systems. Featuring a robust M18 shielded housing, fast response, and IP67 environmental protection, this sensor delivers stable performance in demanding factory environments such as CNC machinery, packaging lines, conveyors, and PLC control systems.
Built with Autonics’ dedicated sensor IC and integrated protection circuits, the PR18-5DP ensures excellent noise immunity, long service life, and consistent switching accuracy — making it an ideal replacement for mechanical limit switches and micro switches.
