STS-8857 - Silonex

STS-8857 Transmissive Switch Assembly

The STS-8857 consists of an infrared emitting diode and an NPN silicon phototransistor mounted on opposite sides of a 3.8 mm wide slot. Phototransistor switching takes place whenever an opaque object passes through the slot. The polysulfone housing (2) reduces interference from ambient light and provides dirt and dust protection. The 40 cm minimum length wir.
