OPB826 OPB822
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.
