De scrip tion
The OPB980 and OPB990 series of
Photologic Photo Integrated Circuit
Switches provide optimum flexibility for
the design engineer. Building from a
standard housing with a .125” wide slot,
the user can specify (1) type and polarity
of TTL output, (2) discrete shell material,
(3) aperture width, and (4) choice of
mounting configuration.
The electrical output can be satisfied as
either TTL totem pole or TTL open
collector. Either may be supplied with
inverter or buffer output polarity. All have
added stability of a built-in hysteresis
amplifier.

UL 1429 insulated wire on each terminal. Insulation colors and functions are:

(6) All parameters tested using pulse techniques.
Hous ing
All housings are an opaque grade of injection-molded plastic to minimize the
assembly’s sensitivity to ambient radiation, both visible and near-infrared. 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.
