Features:
890 nm infrared LED emitter
Silicon phototransistor sensor
Snap-in mounting
Variable sensing distance over 36" (91.4 cm)
Low profile package
24" (61.0 cm) wire leads
Description:
The OPB100 series consists of an infrared LED (OPB100EZ) and phototransistor (OPB100SZ) in separate
plastic housings. The low cost, snap-in design requires no screws or other mounting hardware for ease of
installation.
The emitter and sensor are not apertured, which allows separation distances in excess of 36" (91.4 cm) without
concern for precise alignment. The front side clip allows mounting of the product to any 0.062" (1.57 mm) thick
material.
This product is designed for general switching and low-speed data communications applications.
