DESCRIPTION

The H21L_ and H22L_ 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 'ON' into an 'OFF'

state.
