Features:
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.
For information on encoder design, see Application Bulletin 203 at:
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
Applications:
Non-contact switching
Single or double apertures for high resolution
