PRD18-14DP Autonics Inductive Proximity Sensor
Autonics PRD18-14DP Inductive Proximity Sensor – M18, 14 mm, PNP, DC 3-Wire
Autonics PRD18-14DP is an M18 inductive proximity sensor with 14 mm sensing distance and PNP DC 3-wire output.
Designed for long-range metal detection in PLC-based industrial automation systems.
The Autonics PRD18-14DP is a heavy-duty inductive proximity sensor engineered to detect metal objects only at an extended 14 mm sensing distance. With its M18 threaded housing, non-flush installation, and PNP DC 3-wire output, it is well-suited for conveyors, packaging lines, CNC machines, and PLC-controlled automation where longer detection range improves reliability.
