STS-8831
Dual Channel Optical Switch Assembly
Over / Under Optical Axis
Features
Non contact switching
Four wires for electrical connection
Fast switching speed
Description
The STS-8831 consists of a pair of infrared emitting
diodes and a pair of NPN phototransistors mounted on
opposite sides of a 5.1 mm. wide slot. Phototransistor
switching takes place whenever an opaque object
passes through the slot. The Phototransistors have a
0.5x1.5 mm internal aperture for increased resolution.
The polysulfone housing (Note 1) reduces interference
from
ambient
light
and
provides
dirt
and
dust
protection. 340 mm length wires may be terminated
with an IDC connector upon special order.
