Linear Optical Incremental Encoder Modules

Currently Viewing:

The HEDS-9200 series is a high performance, low cost, optical incremental encoder module. When operated in conjunction with a codestrip, this module detects linear position. The module consists of a lensed LED source and a detector IC enclosed in a small C-shaped plastic package. Due to a highly collimated light source and a unique photodetector array, the module is extremely tolerant to mounting misalignment.

The two channel digital outputs and the single 5 V supply input are accessed through four 0.025 inch square pins located on 0.1 inch centers.

Five standard resolutions between 4.72 counts per mm (120 counts per inch) and 7.87 counts per mm (200 counts per inch) are available. Consult your local Broadcom sales representatives for other resolutions ranging from 1.5 to 7.87 counts per mm (40 to 200 counts per inch).
