DESCRIPTION
The ISTS200_ series of transmissive
photointerrupters are single channel switches
consisting of a Gallium Arsenide infrared
emitting diode coupled to a high speed integrated
circuit detector. The output incorporates a
Schmitt trigger which provides hysteresis for
noise immunity and pulse shaping. The gap in
the plastic housing provides a means of
interrupting the signal with an opaque material,
switching the output from an 'OFF' into an 'ON'
state.
