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 Applications: • Encoders • Non-contact object sensing • Assembly line automation • Machine automation • Equipment security • Machine safety RoHS 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. 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.
