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.
