DESCRIPTION
The H21A_ and H22A_ series of 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. 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.
FEATURES
High Gain
3mm Gap between LED and Detector
Polycarbonate case protected against
ambient light
