Fea tures
•Choice of output configuration
•24” min 26 AWG wires
•Low power consumption
•0.86” (21.8 mm) deep slot
De scrip tion
The OPB917 consists of an infrared
emitting diode and a Photologic photo
integrated circuit mounted in an opaque
housing with clear windows for dust
protection. The extended deep slot
allows for a longer reach of the optical
path from the mounting plane, .900”
(22.86 mm).
Internal apertures are .010” x 0.06” for
the Photologic’s “S side” and .050” x
0.06” for the LED, “E side”. Two logic
states and two electrical output types are
available. Custom electrical, wire or
cabling are available. Contact your local
representative or Optek for more
information.

(5) All parameters tested using pulse technique.
PRECAUTIONS: Exposure of the plastic body to chlorinated hydrocarbons and ketones such
as thread lock and instant adhesive products will degrade the plastic body. Cleaning agents
methanol and isopropanol are recommended. Spray or wipe do not submerge.
