Description
The OPB960 and OPB970 series of
Photologic™ Photo Integrated Circuit
Switches provide optimum flexibility for
the design engineer. Buidling 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) type of
mounting configuration. Available with
24” 26AWG wire leads as
,
OPB980/OPB990 series.
The electrical ouput can be specified 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.
Housing
All housings are an opaque grade of injection-molded plastic to minimize the
assembly’ sensitivity to ambient radiation, both visible and near-infrared. Discrete
s
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.
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
