Optical Encoder
Introduction
Optical Encoder is a electro-mechanical
device which provides the most efficient method of digitizing
the variable properties of a rotating shaft. The optical
encoder is of incremental bi-directional type having
resolution 100 counts per rotation. Pulses appear at
channel A (also called forward channel) whenever there
is clockwise rotation and at channel B (also called
reverse channel) during counter clockwise rotation.
In addition to above a separate reference index output
which indicates the absolute position of shaft is also
provided. The outputs are TTL compatible open collector.
The device works on +5 volts D.C. supply and power consumption
is approximately 1.5 watts.
