DESCRIPTION
This series of photointerrupters are dual
channel switches consisting of two Gallium
Arsenide infrared emitting diodes and two NPN
silicon photo transistors mounted in a "side by
side" configuration on opposite sides of a 2.5mm
wide slot. Dual channels enable direction of
travel sensing. The transmissive housing reduces
possible interference from ambient light and
provides dust and dirt protection. In addition the
ISTS822S, ISTS832S have 0.25mm apertures in
front of the phototransistors, While the
