Omron E3ZM-LS81H 5M Photoelectric Sensor – 100mm Range, PNP Output, Background Suppression, IP67

The Omron E3ZM-LS81H 5M is a compact and durable photoelectric sensor with background suppression designed for reliable object detection in industrial environments. Operating with polarized red light (650 nm) and a 10–100 mm detection range, it delivers stable sensing performance even with reflective or varying backgrounds.

Constructed from stainless steel housing with an IP67 protection rating, this sensor ensures excellent resistance to water, oil, and cleaning agents — ideal for food, packaging, and automation systems. Featuring a PNP normally open output and 10–30 VDC supply range, it supports high-speed switching up to 1000 Hz with a fast 1 ms response time.
