0.5mm APERTURE OPTO-ELECTRONIC SINGLE
CHANNEL WIDE GAP SLOTTED INTERRUPTER
SWITCHES WITH TRANSISTOR SENSORS
DESCRIPTION
3.3
The ISTS802 series of opaque photointerrupters
DIA
are single channel switches consisting of a
1
Gallium Arsenide infrared emitting diode and a
NPN silicon photo transistor mounted in a
2
polycarbonate housing. The package is designed
to optimise the mechanical resolution, coupling
efficiency, ambient light rejection, cost and
11.3
reliability. Operating on the principle that objects
10.9
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
