High Reliability Reflective
Object Sensor
OPB700TX, OPB700TXV
Features:
Non-contact switching
Low profile to facilitate stacking
Hermetically sealed components
24” (609.60 mm) minimum length wire conforms to MIL-W-16878
TX and TXV components processed to MIL-PRF-19500
Description:
Each OPB700TX and OPB700TXV sensor consists of a gallium aluminum arsenide LED and a silicon phototransistor mounted
side‐by‐side on converging op cal axes in a high‐temperature black plas c housing. The phototransistor responds to the
radia on from the LED only when a reflec ve object passes within its field of view. Lead wires are #26 AWG
polytetraflouroethylene (PTEF) insulated, which conforms to MIL‐W‐16878.
TX and TXV device components are processed to OPTEK’s military screening program pa erned a er MIL‐PRF‐19500.
Please refer to Applica on Bulle ns 208 and 210 for addi onal design informa on and reliability (degrada on) data.
