The OPB916 series of Photologic® photo integrated circuit switches provide optimum flexibility. Each switch consists of an
infrared Light Emitting Diode (LED) and a Photologic® photo integrated circuit, mounted in an opaque housing with clear
windows for dust protection. The deep slot allows for a longer reach of the optical path from the 0.650” (16.5 mm)
mounting plane. Internal apertures are 0.010” x .060” (.25 mm x 1.52 mm) for the Photologic’s “S” side and 0.05” x
0.06” (1.27 mm x 1.52 mm) for the LED “E” side.
Devices in this series exhibit stable performance over supply voltages ranging from 4.5 V to 16.0 V, and may be specified as
buffered or inverted with an internal 10 kΩ pull-up resistor or open collector output. Devices are TTL/LSTTL compatible and
can drive up to 10 TTL loads.
Custom electrical, wire or cabling are available. Contact your local representative or OPTEK for more information.
