Description
The OPB700TX and OPB700TXV
consist of gallium aluminum arsenide
LED’ and silicon phototransistors
s
mounted side-by side on converging
optical axes in a high temperature black
plastic housing. The phototransistor
responds to the radiation from the LED
only when a reflective object passes
within its field of view. Lead wires are
#26 AWG polytetraflouroethylene (PTEF)
insulated conforming to MIL-W-16878.
Typical screening and lot acceptance
tests are provided on page 13-4.
