XUN9ANBNM12J00 Square D Photoelectric Sensor, 2m, NPN, M12

The XUN9ANBNM12J00: A 1 ms response time means this sensor resolves targets passing at speeds up to roughly 1 m/s if the object is 1 mm wide — for faster lines, verify the dwell time against your cycle. The 100 mA load capacity covers direct sinking into a PLC input or pilot relay; stay within that limit if driving an external contactor coil without an interposing buffer. Polarized reflex optics use a polarizing filter on the emitter and receiver, so the sensor ignores unwanted reflections from glossy or metallic surfaces as long as the retroreflector stays in clean alignment. Valox body and PMMA lens handle the range between -13°F and 131°F without optical degradation — which tracks typical indoor industrial ambients.
