Encoder Line Drivers

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 performance when the encoder is used in noisy environments, or when it is required to drive long distances.

The 70 degrees C version utilizes an industry standard line driver IC (26LS31) which provides complementary outputs for each encoder channel. The 100 degrees C version utilizes an industry standard line driver IC, 26C31, 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.
