HEDL- 64XX Series Optical
Incremental Housed Encoders
Data Sheet
Description
The HEDL- 64XX series are high
performance, cost effective, two-
channel 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.
