EAW - Absolute Contacting Encoder (ACE™)
General Information
Recommended Control Diagram for ACE-128
Until now, the choice of an absolute
encoder meant an expensive, and larger-
sized product. Through the use of

or at GND.
combinatorial mathematics, the gray-code
pattern of the Bourns Absolute Contacting
Encoder ACE™ is placed on a single track
for a very economical, energy-efficient and
compact product. Bourns’ ACE™ provides
an absolute digital output that will also
retain its last position in the event of a
power failure.
