with Codewheel
Data Sheet
Description
The AEDB-9340 optical encoder series are six-channel
optical incremental encoder modules with codewheel.
The encoder is compliant to RoHS directive and had
been declared as a lead free product. When used with
codewheel, these modules detect rotary position. Each
module consists of a collimated LED source and detector
IC enclosed within a small plastic package. Due to
highly collimated light source and unique photo detec-
tor array designs, these modules are extremely tolerant
to mounting misalignment.
The AEDB-9340 optical encoder has integrated commu-
tation output (U, V, W), two-channel quadrature outputs
plus a third channel index output (A, B, I). This ungated
index output is a positive index pulse that is generated
once for each full rotation of the codewheel.
The AEDB-9340 series optical encoder is designed for
use with a codewheel 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 12 mm (0.472 inch) for 1000/
2000 CPR.
The quadrature, index, commutation signals and power
supplied to encoder are accessed through eight
0.46 mm square male connector pins located on 1.27 mm
(pitch).
The AEDB-9340 optical encoder provides advanced
motion control detection with integrated commutation
outputs (U, V, and W). It is equivalent to those produced
by Hall Switches, thus making it ideal for servo motor
application. With the AEDB-9340 solution, the system will
be more compact, have reduced alignment time with
usage of alignment jig, thus making assembly process
much easier for housed encoder integration. It has
superior switching accuracy due to much lower
hysteresis when compared to a Hall Switches. The com-
mutation signals can be generated for Brushless DC
motor of different rotor pole-pairs by simply changing
with matching pole-pair codewheel.
