AEDL-5xxx & AEDL-981X
High Resolution Kit Encoders (AEDL-5xxx Series)
and Module Encoders (AEDL-981X Series)
Data Sheet
Description
Avago Technologies' AEDL-5xxx and AEDL-981x series
encoders are high performance, low cost, three channel
optical incremental encoders which offer line driver out-
puts. These encoders are designed with an emphasis on
high reliability, high resolution, and easy assembly.
Each encoder contains a LED source with lens, an ASIC with
integrated photo detector arrays, LED current regulation,
interpolator and output driver circuitry, and a code wheel
which rotates between the emitter and detector ASIC. The
outputs of the AEDL-5xxx and AEDL-981x are two square
waves in quadrature. In addition, a third channel offers
index signal, which is a 90 electrical degree, true index
pulse which is generated once for each full rotation of
the code wheel. The AEDL-5xxx series utilizes a film code
wheel allowing for resolutions to 5000 CPR.
The line driver output option offers enhanced perfor-
mance when the encoder is used in electronically noisy
environments, or when it is required to drive long distanc-
es. Both the AEDL-5xxx and AEDL-981x series utilize an in-
dustry 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/, I, I/. Sug-
gested line receivers are 26LS32 and 26LS33.
Standard resolutions between 2000 up to 5000 counts per
revolution are presently available. Please consult your lo-
cal Avago sales representatives for other resolutions.
