OPB822SD

The OPB822SD series Slotted Switch consists of two infrared emitting diodes and two NPN silicon phototransistors mounted on opposite sides of a 0.090” (2.29mm) wide slot. OPB822 uses a side-by-side mounting configuration. OPB822SD has the aperture in front of both phototransistors and both emitters. Dual channels enable direction of travel sensing. With the low-cost plastic housing reduces possible interference from ambient light and provides protection from dust and dirt. Phototransistor switching occurs when an opaque object passes through the device slot.
