Description: OPB804 is a non-contact optical switch with a NPN silicon phototransistor and infrared Light Emitting Diode (LED) which are mounted on opposite sides of a 0.155” ( 3.94 mm) wide slot. The device body is a single molded piece opaque plastic that reduces ambient light interference. A wide open aperture makes it versatile for general applications. LED emissions are near-infrared (850 – 940nm). Features: • Non-contact switch • PCB mount • Wide aperture • Opaque body to minimize sensitivity to ambient light Applications: • Non-contact object sensing • Assembly line automation • Machine automation • Equipment security • Machine safety
