Product Description
H21A2 Slot Optical Switching ,Special use of timer
The H21Ax and H22Ax 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 the infrared emitting diode and the photo sensor,
switching the output from an "ON" state to an "OFF" state. These photoinerrupters are in PWB mounting packages while H21Ax also provides flanges for Screw Mounting
