W Package
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.
