Fea tures
•Non-contact switching
•Low profile to facilitate stacking
•Hermetically sealed components
•Components processed to Optek’s
screening program patterned after
MIL-PRF-19500 for TX and TXV
devices
•24.0 inches (457.2mm) minimum
length lead wires conforming to
MIL-W-16878
De scrip tion
The OPB700TX and OPB700TXV
consist of gallium aluminum arsenide
LED’s and silicon phototransistors
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.

reflectance as a reflective surface.
(3) Crosstalk (ICX) is the collector current measured with the indicated current in the input diode
and no reflecting surface.
(4) “d” is the distance from the assembly head to the reflective surface.
(5) Methanol or isopropyl alcohols are recommended as cleaning agents.
