Autonics PSN17-5DN Inductive Proximity Sensor

Autonics PSN17-5DN Inductive Proximity Sensor is a compact 17 mm square module designed for non-contact detection of ferrous metal objects with a 5 mm sensing distance. It uses a 3‑wire DC supply and an NPN normally open output, typically powered from 10–30 VDC (commonly 12–24 V in many installations). The standard sensing target is 18 × 18 × 1 mm iron, and the sensor housing is ABS with IP67 protection for use in damp or dusty industrial environments. Key electrical specs include a current draw up to 10 mA and a response frequency around 700 Hz, making it suitable for fast position sensing and end‑of‑travel applications. Operational temperature range is -25 °C to 70 °C with 35–95% relative humidity (non-condensing), aligning with typical factory floors and automation cells. Ideal for automation tasks such as chassis and tooling position sensing, conveyor line monitoring, and machine safety interlocks in metalworking, packaging, and robotics setups.
