EAW0J-B24-CE0128L Bourns

Features Absolute encoder / absolute code output Digital output Sturdy construction Bushing mount Available with PC board mounting bracket (optional) *RoHS compliant EAW - Absolute Contacting Encoder (ACE ) Recommended Control Diagram for ACE-128 General Information Until now, the choice of an absolute RESNET 1 8 encoder meant an expensive, and larger- 4609X- 2 7 sized product. Through the use of common is either 101-472 C C combinatorial mathematics, the absolute on a decoded 3 6 code pattern of the Bourns Absolute select pin 4 5 (active low) Contacting Encoder (ACE ) is placed on a or at GND. 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. ACETAB: 256 byte An intelligent alternative to incremental code encoders and potentiometers, the Bourns conversion P1 P2 P3 P4 P5 P6 P7 P8 table (ROM) ACE is ideally suited for many industrial, medical and consumer product applications.
