AEDB-9140-A12 [Agilent]

The AEDB-9140 series are three channel optical incremental encoder modules offered with a codewheel. 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. The modules provide sophisticated motion control detection at a low cost, making them ideal for high volume applications.
