Description
The OPB695 series flag switches consist
of an infrared emitting diode and a
monolithic integrated circuit, which
incorporates a photodiode, a linear
amplifier, and a Schmitt trigger. A lever
arm actuated flag interrupts the light
beam switching the output between
states that can readily drive logic gates.
This switch is designed to easily snap
mount into a 0.037" ± 0.001" (0.94 mm)
thick material with a rectangular opening
of 0.320" ± 0.003" x 0.472" (8.13 mm x
11.99 mm) minimum. Insertion into the
punched side of metal is recommended.

Notes:
(1) Derate linearly 1.33 mW/o C above 25o C.
(2) Derate linearly 2.50 mW/o C above 30o C.
Customized lever arms and spring
torques can be designed for specific
applications.
The device features TTL/LSTTL
compatible logic level output which can
drive up to 10 TTL loads over a voltage
range from 4.5 V to 16 V.
For RoHS compliant devices add "Z" to the end of the
