Data Sheet
Description
The AEDT-9340 optical encoder series are high tempera-
ture six channel optical incremental encoder modules.
When used with a codewheel, these modules detect ro-
tary 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 photo
detector array, these modules are extremely tolerant to
mounting misalignment.
The AEDT-9340 encoder has integrated commutation out-
put channels (U,V,W), two-channel quadrature outputs
(A,B), plus a third channel index output (I). This ungated
index output is a positive index pulse that is generated
once for each full rotation of the codewheel.
The AEDT-9340 encoder is designed for use with a code-
wheel that has an optical radius of 15 mm (0.590 inch) for
1250/2500 CPR, 12.3 mm (0.484 inch) for 1024/2048 CPR
and 12mm (0.472 inch) for 1000/2000 CPR.
The quadrature, index, commutation signals and power
supplied to encoder are accessed through eight 0.46mm
square male connector pins located on 1.27mm pitch.
The AEDT-9340 optical encoder provides advanced mo-
tion control detection. The integrated commutation out-
puts (U,V, and W) is equivalent to those produced by Hall
Switches. Thus, this makes to encoder ideal for servo mo-
tor applications. Application of the AEDT-9340 solution
also enables the system to be more compact, with a sig-
nificantly reduced alignment time. This is due to the pro-
vision of alignment jigs for easier assembly into housed
encoders. The encoder also provides superior switching
accuracy due to a much lower hysteresis when compared
to a Hall Switches. The commutation signals can easily
be interchanged for Brushless DC motor of different ro-
tor pole-pairs by simply switching to matching pole-pair
codewheels.
