C Versions
Available
The 70°C version utilizes an
industry standard line driver IC
(26LS31) which provides comple-
mentary outputs for each encoder
channel. The 100°C version utilizes
an industry standard line driver IC,
26C31, which provides comple-
mentary outputs for each encoder
channel. Thus, the output of the
line driver encoder is A, A, B, B
and I/I for three channel versions.
Suggested line receivers are
26LS32 and 26LS33.
For additional information,
please refer to:
HEDS-5500/5540/5600/5640
data sheet,
HEDS-90x0/91x0/92x0 data
sheets,
HEDS-9000 series extended
resolution data sheet, and
26LS31 data sheet.
Description
Line Drivers are available for the
HEDS-55xx/56xx series and the
HEDS-9000/9100/9200/9040/
9140 series encoders. The line
driver offers enhanced perform-
ance when the encoder is used in
noisy environments, or when it is
required to drive long distances.
Note:
Agilent Technologies
encoders are not recommended
for use in safety critical
applications. Eg. ABS braking
systems, power steering, life
support systems and critical care
medical equipment. Please
contact sales representative if
more clarification is needed.
