Sensing distance is 2 m, response time 1 ms on/off, and operating frequency 500 Hz. Enclosure is NEMA 4X/12 and IP67, rated from -13 to 131 °F. Connection via 4-pin micro connector (3 wires). UL, CSA, CE listed.
18 mm threaded barrel, 4-pin micro connector, and three-wire PNP output. Yellow LED indicates output state; light/dark mode selectable. Polarized retroreflective optics reject false triggers from shiny targets. Mount with the retroreflector at 2 m or less. The stainless steel housing withstands washdown environments (NEMA 4X, IP67).
