The Omron E3Z-LR61 2M Photoelectric Sensor delivers exceptional long-distance detection using a retro-reflective sensing method with built-in MSR (Mirror Surface Rejection) function. Featuring a laser light source (655 nm) and a detection range of 0.2 to 7 meters, it ensures reliable object detection even in challenging industrial environments. Its Class 1 laser rating under JIS, IEC, and FDA standards ensures both performance and operator safety.
This compact photoelectric sensor offers rapid 1 ms response time, robust PBT housing, and a durable IP67 protection rating that withstands vibration, shock, and extreme ambient conditions. The pre-wired 2-meter cable, adjustable sensitivity (via one-turn adjuster), and dual LED indicators simplify installation, troubleshooting, and calibration in dynamic production setups.
Engineered for automation systems requiring precision and durability, the E3Z-LR61 supports NPN open collector outputs and operates within 12–24 VDC. It is trusted by engineers across material handling, packaging, and object detection lines.
