TB12 Through Beam Sensors

TB12 Through Beam Sensors

The TB12 Through-Beam Sensor has a 12mm housing with a low profile front flange and plastic locking nut. This design is ultra-rugged and epoxy encapsulated to IP67 rating. Ideal for tight places and has crosstalk rejection between two beam pairs to deliver no false triggers. Ultra-Low-power design, perfect for battery powered automation!
