The outputs of the AEDC-5xxx are two square waves -40 C to 85 C operating temperature in quadrature. In addition, a third channel offers index Applications signal, which is a 90 electrical degree, true index pulse which is generated once for each full rotation of the code High volume applications such as printers, plotters, tape wheel.
