DESCRIPTION
The ISTS823A, ISTS824A opaque
photointerrupters are single channel switches
consisting of a Gallium Arsenide infrared
emitting diode and a NPN silicon photo transistor
mounted in a polycarbonate housing with 450mm
flying leads. The package is designed to optimise
the mechanical resolution, coupling efficiency,
ambient light rejection, cost and reliability.
Operating on the principle that objects opaque to
infrared will interrupt the transmission of light
between an infrared emitting diode and a photo
sensor switching the output from an "ON" state to
an "OFF" state.
