General Information

*RoHS COMPLIANT

Until now, the choice of an absolute

encoder meant an expensive, and larger-

sized product. Through the use of

combinatorial mathematics, the absolute

code pattern of the Bourns® Absolute

Contacting Encoder (ACE™) is placed on a

single track for a very economical, energy-

efﬁ cient and compact product. Bourns®

ACE™ provides an absolute digital output

that will also retain its last position in the

event of a power failure.

An intelligent alternative to incremental

encoders and potentiometers, the Bourns®

ACE™ is ideally suited for many industrial,

automotive, medical and consumer product

applications.
