Bourns EAW0JC24AE0128L Absolute Contacting Encoder

The Bourns Absolute Contacting Encoder (ACE) represents a significant advancement in encoder technology, providing a cost-effective and compact alternative to traditional absolute encoders and potentiometers. Utilizing combinatorial mathematics, the ACE places the absolute code pattern on a single track, resulting in a smaller footprint and improved energy efficiency. A key feature is its ability to retain the last known position during power failures, enhancing reliability in critical applications. The ACE is well-suited for a wide range of industrial, automotive, medical, and consumer product applications where precise and reliable position feedback is required.
