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.

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.
