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.

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.

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.
