Design & Manufacture
Mouser now stocks Avago Technologies AEDC-5xxx series encoders. The devices
provide a connector latch on the cover housing to improve connector
retention. They are built upon the proven Avago AEDT-9810 series encoder
module and provide the same performance, low cost, high reliability, high
resolution and ease of assembly.
Each encoder contains a LED source with lens, an ASIC with integrated photo
detector arrays, LED current regulation, interpolator and output driver
circuitry, and a code wheel which rotates between the emitter and detector
ASIC.
The outputs of the AEDC-5xxx are two square waves in quadrature. In
addition, a third channel offers index signal, which is a 90 electrical
degree, true index pulse which is generated once for each full rotation of
the code wheel. The AEDC-5xxx series utilizes a film code wheel allowing for
resolutions up to 5000 CPR and accommodating shaft diameters from 2mm to
8mm.
