Schneider Electric XURK1KSMM12 Photoelectric Sensor

Schneider Electric Telemecanique XURK1KSMM12 is a compact diffuse photoelectric sensor in the XU family that detects small objects at close range with a 9 mm nominal sensing distance. Housed in a zinc‑alloy enclosure with a glass lens, it uses a 4‑pin M12 connector and a 3‑wire wiring scheme for DC operation. The unit operates on a 12–24 V DC supply with reverse polarity protection and delivers versatile switching through a discrete output that can be PNP or NPN and configured as 1 normally open or 1 normally closed contact. An additional analogue output ranges 0–5.5 V DC to convey proximity information in compatible control schemes. The emitter provides red or green light, enabling reliable sensing across different materials, and the device is designed for compact installations where diffuse sensing of very small targets is required; the detector can sense marks as small as 0.5 mm and tolerates object inclination up to 20 degrees. The XURK1KSMM12 embodies Telemecanique’s XU series with flexible output options and a robust metal enclosure suitable for integration into automation circuits.
