High Reliability Slotted Optical Switch OPB870, OPB871, OPB872 (TX, TXV) L Features: • • • • • • 0.125” (3.175 mm) slot width Choice of aperture (0.050” or 0.010” width) PCBoard mounting TX and TXV devices processed to MIL-PRF-19500 S level processing available Hermetically sealed components N T Product Photo Here P Description: Each OPB870, OPB871 and OPB872 (TX, TXV) phototransistor device provides the flexibility of a custom device from a standard product line. Building from a standard housing with a 0.125” (3.175 mm) wide slot and 0.425” ( mm) leads for PCBoard mounting, a user can choose aperture width, opaque or IR transmissive housing shell material and mounting tab configuration. Housings are made from an opaque grade of injection-molded plastic to minimize sensitivity to both visible and near-infrared light. Discrete shells exposed on the parallel faces inside each device’s throat are made from either IR transmissive plastic (for applications where dust protection is needed) or from opaque plastic with aperture openings (for applications that require maximum protection against ambient light). TX and TXV devices are processed to OPTEK’s military screening program patterned after MIL-PRF-19500. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data. Contact your local representative or OPTEK for more information.
