OPB695
Each OPB685 and OPB695 series flag switch consists of an infrared emitting diode and a monolithic integrated circuit that
incorporates a photodiode, a linear amplifier and a Schmitt trigger. A lever arm actuated flag interrupts the light beam,
which switches the output between states that can readily drive logic gates.
The OPB695 series is designed to easily snap mount into a 0.037” ± 0.001” (0.940 mm ± 0.025 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.
Devices in these series feature TTL/LSTTL compatible logic level output that can drive up to 10 TTL loads over a voltage
range from 4.5 V to 16 V.
Customized lever arms and spring torques can be designed for specific applications for each of the devices.
Custom electrical, wire, cabling and connectors are available. Contact your local representative or OPTEK for more
information.
