Absolute encoder gray code output Digital output Sturdy construction Bushing mount Available with board mounting bracket (optional)
Absolute Contacting Encoder (ACETM)
General Information
Until now, choice absolute encoder meant expensive, largersized product. Through combinatorial mathematics, gray-code pattern Bourns Absolute Contacting Encoder ACEis placed single track very economical, energy-efficient compact product. Bourns' ACEprovides absolute digital output that will also retain last position event power failure. intelligent alternative incremental encoders potentiometers, Bourns ACEis ideally suited many industrial, automotive, medical consumer product applications.
