EAW0J-C24-AE0128L is an Absolute Contacting Encoder (ACE™) manufactured by Bourns that provides absolute digital output with 128 states per revolution and non-detented operation. The encoder features a 9 mm bushing mount with M9×0.75 threaded connection, a 1/4" diameter plain shaft with inserted slot (Shaft Style B), and an anti-rotation lug positioned at the 9:00 position. It delivers absolute position data through a combinatorial mathematics-based single-track design, ensuring compact and economical operation while retaining the last position in the event of power failure. The device is ideal for industrial, automotive, medical, and consumer applications requiring reliable position feedback without the need for power-dependent incremental tracking.
