M18 5m Proximity Switch The M18 E3F‑5L/E3F‑5DP1 Photoelectric Sensors are reliable, easy‑to‑wire DC proximity switches for object detection on conveyors, packaging lines, doors, and general automation. With a standard M18 threaded housing and 3‑wire DC input (6–36 VDC), they drop into most control panels and PLC inputs with minimal setup. Choose the output you need—NPN or PNP, NO/NC (model dependent). A bright status LED confirms target detection at a glance, and the IP65‑class housing with locking nuts keeps alignment stable even in dusty environments. Quick response and stable detection help improve throughput and reduce false trips.
