PRL30-15DN Autonics Proximity Sensor
Autonics PRL30-15DN Inductive Proximity Sensor – M30, 15 mm, NPN, DC 3-Wire
Autonics PRL30-15DN 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 PLC-controlled industrial automation.
The Autonics PRL30-15DN is a heavy-duty cylindrical inductive proximity sensor designed to detect metal objects only in demanding industrial environments. With its M30 threaded housing, 15 mm sensing distance (non-flush), and NPN DC 3-wire output, it provides reliable long-range detection for conveyors, material handling systems, and large industrial machinery connected to PLC digital inputs.
