AEDL-5xxx Quick Assembly High Resolution Three Channel Optical Encoders with Differential Output Data Sheet Description Features The AEDL-5xxx series encoders are high performance, low High resolution up to 5000 CPR cost, three channel optical incremental encoders which Operating temperature -40C to +85C offer line driver outputs. These encoders emphasize on User friendly installation process high reliability, high resolution, and easy assembly. Complementary Outputs with industry standard Line Each encoder contains a LED source with lens, an ASIC Driver IC with integrated photo detector arrays, LED current regula- Single 5 V Supply with 10% tolerance tion, interpolator and output driver circuitry, and a code wheel which rotates between the emitter and detector Onboard decoupling capacitor for enhance noise ASIC. The outputs of the AEDL-5xxx is two square waves immunity 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 al - lowing for resolutions to 5000 CPR. The line driver offers enhanced performance when the encoder is used in electronically noisy environments, or when it is required to drive long distances. AEDL-5xxx se- ries utilize an industry standard line driver IC, AM26C31Q, which provides complementary outputs for each encoder Note: Avago Technologies encoders are not recommend- channel. Thus, the output of the line driver encoder is ed for use in safety critical applications such as. ABS brak- A, A/, B, B/, I, I/. Suggested line receivers are 26LS32 and ing systems, power steering, life support systems and 26LS33. critical care medical equipment. Please contact our sales representative if clarifications are needed. Standard resolutions from 1000 to 5000 counts per revo- lution are presently available. Please consult local Avago sales representatives for other resolutions.
