Industrial IAS-20-A12-S IA0246 Proximity Switch Sensor

The Rechner IAS-20-A12-S IA0246 is a compact 12 mm M12-threaded inductive proximity switch with a 2 mm sensing distance, designed for metal-target detection in industrial automation. This 3‑wire DC sensor operates from 10–30 V DC and provides a normally open (NO) NPN output capable of switching up to 200 mA, with a maximum voltage drop of 3 V and switching frequencies up to 1.5 kHz. It uses a nickel-plated brass housing with a PBT active surface, and comes with a 3 m PUR cable (3 x 0.14 mm²) for robust field connections. The device is rated IP67 for ingress protection and is specified to operate from −25 to +70 °C, conforming to EN 60947-5-2 standards for inductive proximity sensors. Typical applications include end‑of‑travel and position sensing in automation rigs, fixture alignment, and other metal‑presence detection tasks where a compact, rugged sensor is required. The part is identified as IA0246 (IAS-20-A12-S, NPN, NO) and is suitable for use in control circuits that accept a 10–30 V DC supply and a 200 mA load.
