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

single track for a very economical, energy-

efﬁ cient and compact product. Bourns’

ACE

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

automotive, medical and consumer prod-

uct applications.
