Avago Technologies announced a new series of compact three-channel high temperature optical incremental encoder modules for use in industrial and factory automation equipment. Avago’s AEDT-9140 encoder module series, which are available in a variety of counts per revolution (CPR) and shaft diameter options, are priced competitively and designed to enable the reduction in overall motor sizes. This latest addition to Avago’s family of easy to install optical encoders are designed to fit easily into a circular housed encoder or directly onto industrial motors to provide motor manufacturers with advanced motion control detection.
The AEDT-9140 encoder modules include a lensed LED source and a detector IC enclosed in a small plastic package. When used with a codewheel, this low-cost module series detects rotary position. Due to a highly collimated light source and a unique photodetector array, the AEDT-9140 modules are extremely tolerant to mounting misalignment. Typical industrial automation applications where the AEDT-9140 encoders can be used include industrial printers, plotters, tape drives, machine tools and industrial and factory automation equipment.
Avago’s AEDT-9140 modules have two channel quadrature outputs plus a third channel index output and are designed for use with a codewheel that has an optical radius of 11 mm (0.433 inch) for 100 to 512 CPR and 11.68 mm (0.460 inch) for 1,000 CPR. The index output is a 90 electrical degree high true index pulse which is generated once for each full rotation of the codewheel.
