Photodiode Arrays Serve Encoder Duties

For use in incremental encoder applications, the OSM960 is a six-element photodiode array that provides differential analog outputs for A and B quadrature channels as well as an index or marker pulse channel. The large active areas of the photodiodes results in fast response times and high sensitivity. Signals are suitable for both low- and high-resolution applications.The device is housed in a 12-pin, SO-style surface-mount package that features a choice of holes or pins for alignment of reticles or masks. The package is rated for operation from -55ºC to 110ºC. The array is suited for use with encoder disks that are approximately 2" in diameter or greater.
