If you've got a panel wired for the E3ZR812MOMI, this part drops into the same footprint — same 10.8 x 31 x 20 mm envelope, same PNP output, same sensing and power specs. The only real difference is the termination: this one comes pre-wired (cable), the sibling uses a cable pigtail as well (not connector). For a replacement on site, it's a straight swap; just match the cable length to your existing routing. ## Mount it and forget it IP67 means you can hose it down on a food line or mount it under a washdown station. The red LED light source is visible during alignment — no special tools needed. Response time is fast enough for high-speed count and presence on a 1 ms cycle. Keep the ambient below 55 °C and above -25 °C, and the sensor's happy.","metaTitle":"Omron E3ZR81M3J03MOMS Retro-Reflective Sensor, PNP, 4m","metaDescription":"Retro-reflective photoelectric sensor, PNP, 4 m sensing range, 1 ms response, 12–24 VDC, IP67, pre-wired.
