PR30-15DN Autonics Inductive Proximity Sensor
Autonics PR30-15DN Inductive Proximity Sensor – M30, 15 mm, NPN, DC 3-Wire
Autonics PR30-15DN is an M30 inductive proximity sensor with a 15 mm sensing distance and NPN DC 3-wire output.
Designed for long-range metal detection in heavy industrial automation and PLC-based systems.
The Autonics PR30-15DN is a heavy-duty inductive proximity sensor engineered to detect metal objects only at a long sensing distance. Featuring a robust M30 threaded housing, 15 mm sensing range (non-flush), and NPN DC 3-wire output, it is ideal for conveyors, steel plants, heavy machinery, and PLC-controlled industrial automation systems.
