... Three Channel Optical Incremental Encoder Modules Data Sheet Description The HEDS-9040 and HEDS-9140 series are three channel optical incremental encoder modules. When used with a codewheel, these low cost modules detect rotary position. Each module consists of a lensed LED source and a detec- tor IC enclosed in a small plastic package ...

... The HEDS-9040 is designed for use with a HEDX-614X code wheel which has an optical radius of 23.36 mm (0.920 inch). The HEDS-9140 is designed for use with a HEDx-5x4x code wheel which has an optical radius of 11.00 mm (0.433 inch). The quadrature signals and the index pulse are accessed through fi ...

... The HEDS-8905 and HEDS-8906 alignment tools are rec- ommended for mounting the modules with Side B as the mounting plane. The HEDS-8905 is used to mount the HEDS-9140, and the HEDS-8906 is used to mount the HEDS-9040. These tools fi x the module position using the codewheel hub as a reference. They will not work if Side A is used as the mounting plane ...
