Photologic® Optical Flag Switch
Types OPB685, OPB686, OPB687, OPB688
Features
• Photologic® output
• Four output options
• Mechanical switch replacement
• Printed circuit board mounting
Description
The OPB685 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.
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.
