Description
The HEDS-65xx/HEDL-65xx
are high performance two and three
channel optical incremental
encoders. These encoders empha-
size high reliability, high resolution,
and easy assembly. Each encoder
contains a lensed LED source
(emitter), an integrated circuit with
detectors and output circuitry, and a
codewheel which rotates between
the emitter and detector integrated
circuit. The outputs of the HEDS-
6500 are two single ended square
waves in quadrature. The HEDL-
65xx outputs are differential.
The HEDS-6540 / HEDL-6540 also
have a third channel index output in
addition to the two quadrature

outputs. This index is an active
high pulse that occurs once every
full rotation of the codewheel.
Resolutions up to 1024 Counts Per
Revolution are available in the two
and three channel versions.
The line driver option offers
enhanced performance when the
encoder is used in noisy environ-
ments, or when it is required to
drive long distances.
The line driver option utilizes an
industry standard line driver IC
(26C31) which provides comple-
mentary outputs for each encoder
channel. Thus the outputs of the
line driver encoder are A and
and
channel versions. Suggested line
receivers are 26C32 and 26C33.
The quadrature signals are ac-
cessed through a cable and 10-pin
female connector. Please refer to
the ordering information at the end
of this data sheet for a selection
matrix.

very high resolution and accept a
variety of shaft sizes up to a
maximum of 5/8 inches.

... Theory of Operation The HEDS-65xx / HEDL-65xx translate the rotary motion of a shaft into either a two or three channel digital output. The HEDS-65xx uses one of the standard HEDS-9000 or HEDS-9040 modules for encoding purposes. The HEDL-654x uses the standard HEDL-9040 for encoding purposes. As seen in the block diagram, ...
