Dual Channel Encoder OPB822S, OPB822SD OPB826S, OPB826SD Features: * * * * * Non-contact switching Single or double apertures for high resolution Choice of slot widths Choice of side-by-side or over/under dual channels Choice of electrical outputs OPB826 OPB822 Description: Each OPB822 and OPB826 slotted switch consists of two infrared emitting diodes and two NPN silicon phototransistors mounted on opposite sides of a 0.090" (2.29 mm) wide slot (OPB822) or a 0.100" (2.54 mm) wide slot (OPB826). OPB822 uses an side-by-side mounting configuration, while OPB826 uses an over/under mounting configuration. OPB822S has 0.01" by 0.04" (0.25 mm x 1.02 mm) apertures in front of both phototransistors while the OPB822SD has the aperture in front of both phototransistors and both emitters. The OPB826S has 0.04" by 0.04" (1.02 mm x 1.02 mm) apertures in front of both phototransistors while the OPB826SD 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.
