Description:
The OPB917 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
Photologics 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 k& 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.
Applications:
" Mechanical switch replacement
" Speed indication (tachometer)
" Mechanical limit indication
" Edge sensing
