Micro Detectors – FAR3/BN‑2E – M18 90° Diffuse Photoelectric Sensor, NPN NO+NC
The Micro Detectors FAR3/BN‑2E is an M18-threaded, 90° diffuse (right-angle beam) photoelectric sensor with on-board sensitivity adjustment. It features dual NPN outputs (normally open + normally closed), designed for precise object detection up to 100 mm. Housed in durable plastic with an M12 plug connector, it’s ideal for space-constrained machine vision, packaging, and conveyor systems.
