Avago Technologies Announces Miniature Three-Channel Optical Incremental Encoder with Integrated Codewheel for Industrial Apps
Compact Bearing-less Encoder Provides Designers with a High
Frequency Housed Encoder Solution that Offers Up to 500 CPR, and Easy
Installation
CHIBA, Japan--(Business Wire)--
Avago Technologies today announced a new series of miniature low
cost, high performance three-channel housed optical incremental
encoders for use in a wide range of office and industrial automation
applications. Avago's AEDx-8xxx encoder series, which includes a
codewheel, LED light source and detector IC enclosed in a plastic
package has been specifically designed for use in stepper motors,
miniature servo motors, packaging machines and a wide range of
industrial and factory automation applications. Avago is a leading
supplier of analog interface components for communications, industrial
and consumer applications.
The AEDx-8xxx housed optical encoder is bearing-less and has
integrated two-channel quadrature outputs and a third channel index
output (A, B, I). The ungated index output is a positive index pulse
that is generated once for each full mechanical revolution of the
codewheel. The quadrature index and power supplied to the encoder are
accessed through an eight-pin male connector on a 1.25 mm pitch. This
new miniature housed encoder series is designed for use with motors
that have shaft diameters from 2mm (miniature version) up to 5mm
(standard option). Moreover, due to the highly collimated light source
and the unique photo detector array design, the AEDx-8xxx is extremely
tolerant to mounting misalignment.
Avago's AEDx-8xxx series offers several benefits such as minimal
installation cost, ease of assembly, high operating frequency that
supports miniature servo motors (up to 24K RPM), and more accurate
position control with the use of an index as a reference point. This
encoder solution is also compatible with SMT automation equipment and
pick and place machines. Moreover, this encoder series can operate in
temperatures from -40 to 100 degrees C to meet most industrial
temperature requirements. Typical applications include industrial
printers and plotters, tape drives, industrial sewing machines,
packaging machines and industrial and factory automation equipment.
