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.

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.
