High Temperature 115qC
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 1000 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.
