Description The HEDL- 64XX series are high performance, cost effective, twochannel optical incremental housed encoders with optional index pulse. These encoders emphasize high reliability, high resolution and easy assembly. The HEDL- 64XX housed encoders use transmissive technology to sense rotary position. This sensor consists of an LED light source, a photodetector IC and line driver. The outputs of the HEDL- 64XX encoders are 2 square waves in quadrature and and an optional gated index pulse. These encoders may be quickly and easily mounted to a motor.

Theory of Operation The HEDL- 64XX translates rotary motion of a shaft into a two or three channel digital output. The HEDL- 64XX series has four key parts: a single light emitting diode (LED) light source, a photodetector IC with a set of uniquely configured photodiodes , a line drive IC and a pair of lenses. The lens over the LED focuses ligh...
