Photologic® Slotted Optical Switch
OPB930 and OPB940 (L and W Series)
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Features:
• Choice of aperture size
• Choice of output configurations
• Choice of opaque or IR transmissive shell
• Choice of pins (L) or wires (W)
• 0.125” (3.18 mm) slot width
• 0.320” (8.128 mm) lead spacing for PCBoard (side mounting)
• Data rates to 250 kBaud
Description:
The OPB930 and OPB940 series of Photologic® photo integrated circuit switches provide optimum flexibility for
the design engineer. Building from a standard housing with a 0.125” (3.18 mm) wide slot, a user can specify the
type and polarity of TTL output, discrete shell material, aperture width and either 0.350” (8.9 mm) long pins
(L Series) or 24” (610 mm) AWG, UL listed wire leads (W Series).
All housings are made from an opaque grade of injection-molded plastic that minimizes the assembly’s sensitivity
to both visible and near-infrared ambient radiation. Discrete shells (exposed on the parallel faces inside the device
throat) are either IR transmissive plastic (for applications where aperture contamination may occur) or opaque
plastic (for maximum protection against ambient light).
Electrical output can be specified as either TTL Totem Pole or TTL Open Collector, either of which can be supplied
with buffer or inverter output polarity. All devices have the added stability of a built-in hysteresis amplifier.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.

To avoid stress cracking, we suggest using ND
Industries’ Vibra-Tite for thread-locking.
Vibra-Tite evaporates fast without causing
structural failure in OPTEK’s molded plastics.
