Three Channel Optical Encoders
Data Sheet
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
Description
Avago Technologies' AEDM-5xxx series encoders are high
resolution and high performance three channel optical
incremental encoders. These encoders emphasize on high
reliability, high resolution, and easy assembly.
Each encoder contains a LED source with lens, an ASIC
with integrated photo detector arrays, LED current regula-
tion, interpolator and output driver circuitry, and a code
wheel which rotates between the emitter and detector
ASIC. The outputs of the AEDM-5xxx are two square waves
in quadrature. In addition, a third channel oers index
signal, which is a 90 electrical degree, true index pulse
which is generated once for each full rotation of the code
wheel. The AEDM-5xxx series utilizes a lm code wheel al-
lowing for resolutions up to 5000 CPR.
These bearing-less housed encoders may be quickly and
easily mounted to a motor. For larger diameter motors, the
AEDM-59xx series feature external mounting ears option.
The quadrature signals and the index pulse are accessed
through ve 0.025 inch square pins located on 0.1 inch
centers.
Standard resolutions between 2000 and 5000 counts per
revolution are presently available. Consult local Avago
sales representatives for other resolutions.
