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.
