Optical Encoder Modules 4-Pin

The HEDS-973X is a high performance incremental encoder module. When operated in conjunction with either a codewheel or codestrip, this module detects rotary or linear position. The encoder consists of a lensed LED source and a detector IC enclosed in a small Cshaped 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 3.3V supply input are accessed through four solder plated leads located on 2.54mm (0.1inch) centers. The standard HEDS-973X is designed for use with an appropriate optical radius codewheel or linear codestrip. Other options are available.
