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.
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
line
and
dB–r,ivaenrdeInacnodde–Ir
are A and
for three
t–Ah,eB
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.
The HEDS-6540 / HEDL-6540 also
have a third channel index output in
addition to the two quadrature
Applications
The HEDS-65xx / HEDL-65xx
provide motion detection to a
very high resolution and accept a
variety of shaft sizes up to a
maximum of 5/8 inches.

Note: The HEDS-65XX performance is guaranteed to 100 kHz but can operate at higher frequencies. For frequencies above 100 kHz
it is recommended that the load capacitance not exceed 25 pF and pull up resistors of 3.3 kΩ between the output channels and Vcc
are included.
