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.
