AEDL-5xxx series encoders are high performance, low cost, three channel optical incremental encoders which offer line driver outputs. 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 performance when the encoder is used in electronically noisy environments, or when it is required to drive long distances. Both the AEDL-5xxx and AEDL-981x series utilize 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/, I, I/. Suggested line receivers are 26LS32 and 26LS33. Standard resolutions between 2000 up to 5000 counts per revolution are presently available.
