The PNP output, pre-wired cable, and IP67 rating suit it for conveyor lines, packaging machines, and washdown zones where a reliable diffuse or through-beam is not feasible. Sensing distance is 7 m down to 200 mm with a suitable reflector (not included). The 1 ms response keeps up with high-speed counting but watch the load current—100 mA maximum, enough for a PLC input and a small indicator, not a contactor coil directly. The closest sibling is the E3ZLR86OMS: same housing, same 7 m range, same PNP output, but it uses a red laser instead of LED and terminates with an M8 connector instead of a pre-wired cable. The laser gives a visible spot for alignment but carries Class 1 eye-safety restrictions and typically costs more. If your panel uses M8 pigtails and you need a visible aiming aid, the E3ZLR86OMS is a drop-in swap mechanically—same footprint and mounting hole pattern. Otherwise the LED pre-wired version here is the standard retro-reflective choice for most applications. 10.8 mm wide, 31 mm tall, 20 mm deep; fits DIN-rail mounts. Light-ON/Dark-ON selectable. Operates -10 to 55 °C, 12–24 V, 100 mA load.","metaTitle":"Omron E3ZLR81M1J03MOMS Retro-Reflective Sensor, PNP, 7m","metaDescription":"Omron E3ZLR81M1J03MOMS retro-reflective photoelectric sensor, PNP output, 7 m range, 1 ms response, 12–24 V, pre-wired, IP67.
