Description

Line Drivers are available for the HEDS-55xx/56xx series

and the HEDS-9000/9100/9200/9040/9140 series encod-

ers. The line driver offers enhanced performance when

the encoder is used in noisy environments, or when it is

required to drive long distances.

The encoder line driver utilizes an industry standard line

driver IC, AM26C31Q, which provides complementary

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.

Note: Avago 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 con-

tact sales representative if more clarification is needed.
