Features:

housing and 4809 series terminal for OPB695 Series

Description:

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.
