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 1.02 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.

To avoid stress cracking, we suggest using
ND Industries’ Vibra-Tite for thread-locking.
Vibra-Tite evaporates fast without causing structural failure in
OPTEK’s molded plastics.

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/°C above 25° C.
(3) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and ketones. Spray and
wipe; do not submerge.
(4) Derate linearly 3.33 mW/°C above 25° C.
(5) All parameters tested using pulse techniques.
(6) Feature controlled at body.
