PRD12-8DP Autonics Proximity Sensor
Autonics PRD12-8DP Inductive Proximity Sensor – M12, 8 mm, PNP, DC 3-Wire
Autonics PRD12-8DP is a compact M12 inductive proximity sensor with an 8 mm sensing distance and a PNP DC 3-wire output.
Suitable for long-range metal detection in space-constrained PLC-based automation systems.
The Autonics PRD12-8DP is a compact inductive proximity sensor designed to detect metal objects only with an extended 8 mm sensing distance. Featuring an M12 threaded housing, non-flush installation, and PNP DC 3-wire output, it is ideal for compact machines, OEM equipment, and PLC panels where a longer detection range is needed without increasing sensor size.
