AEDT-9140 Series

High Temperature 115ºC

Three Channel Optical Incremental Encoder Modules 100 CPR to 1000 CPR

Data Sheet

Description

The AEDT-9140 series are three channel optical incremen-tal encoder modules. When used with a codewheel, these low cost modules detect rotary position. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photodetector array, these modules are extremely tolerant to mounting misalignment.The AEDT-9140 has two channel quadrature outputs plus a third channel index output. This index output is a 90 electrical degree high true index pulse which is generated once for each full rotation of the codewheel.

The AEDT-9140 optical encoder is designed for use with a codewheel which has an optical radius of 11.00 mm (0.433 inch) for 100 CPR to 512 CPR and 11.68 mm (0.460 inch) for 1000 CPR.

The quadrature signals and the index pulse are accessed through five 0.46 mm square pins located on 1.27 mm (pitch) centers.
