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