The Telemecanique XU2M18MA230K is a 15m through-beam photoelectric sensor from the XU2 tubular series. It runs on universal supply 24 to 240 VAC/VDC, outputs a dark-operate signal (load present when the beam is broken), and switches loads up to 200 mA. The M12 3-pin AC/DC micro male connector mates to standard sensor cables; make sure your control logic expects dark operate or invert downstream.
The XU2M18MA230K is an M18 threaded nickel-plated brass barrel, front-sensing, with NEMA 4X/12 and IP67 sealing. It's built for wet washdown or dusty environments. The 20-millisecond on/off response time limits it to moderate-speed object detection — not for high-speed counting on a fast line. Pair it with the matching XU2 emitter (separate order) for the through-beam pair; the receiver listed here only works with a compatible emitter.
This sensor is listed as current production. No last-time-buy or phase-out is in effect. Approvals are UL, CSA, CE — documented for panel compliance. No direct drop-in second-source is published from other manufacturers, so if this is a BOM line, confirm emitter compatibility and lock the order.
