Optical Incremental Encoder Module

The AEDB-9140 series are three channel optical incremental encoder modules offered with a codewheel. When used with a codewheel, these low cost modules detect rotary position. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photodetector array, these modules are extremely tolerant to mounting misalignment. The AEDB-9140 has two channel quadrature outputs plus a third channel index output. This index output is a 90 electrical degree high true index pulse which is generated once for each full rotation of the codewheel. The AEDB-9140 is designed for use with a codewheel which has an optical radius of 11.00 mm (0.433 inch). The quadrature signals and the index pulse are accessed through five 0.46 mm square pins located on 1.27 mm(pitch) centers.
