AEDS-9240 Series
360/720 CPR Commutation Encoder Module
Data Sheet
Description
The AEDS-9240 optical encoder is a six channel optical
incremental encoder module. When used with a code-
wheel, this encoder detects 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 photo detector array, these modules
are extremely tolerant to mounting misalignment.
The AEDS-9240 encoder is designed with integrated com-
mutation output channels (U,V,W), two-channel quadra-
ture outputs (A,B), plus a third channel ungated index
output (I). This ungated index output is a positive index
pulse that is generated once for each full rotation of the
codewheel.
The AEDS-9240 encoder is designed for use with a code-
wheel that has an optical radius of 19.00 mm (0.748 inch)
to obtain an optimum 360/720 CPR (count per revolution)
resolution.
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 AEDS-9240 optical encoder also provides advanced
motion control detection. Its integrated commutation
outputs (U,V, and W) is equivalent to those produced by
Hall Switches. Thus, this makes the encoder ideal for servo
motor applications. Application of the AEDS-9240 en-
coder also enables motor systems to be more compact.
In addition, the provision of alignment jigs enables a sig-
nificantly reduced production time and ease of assembly
into housed encoders. The encoder also provides superior
switching accuracy due to a much lower hysteresis when
compared to Hall Switches. Its commutation signals can
easily be interchanged for Brushless DC motor of different
rotor pole-pairs by simply switching to matching pole-
pair codewheels.
