Bourns Absolute Encoder (EAW0J-B24-AE0128L)

The Bourns Absolute Encoder is a high-precision digital control knob that delivers a total of 128 unique results, evenly distributed around a full circle. It is primarily designed to function as a control panel knob, but its versatile nature allows it to be adapted for a variety of other uses. This absolute encoder is a superior alternative to a potentiometer and analog pin, as it supports full-turn and multi-turn operations.

What sets the Bourns Absolute Encoder apart from the standard incremental rotary encoder is its ability to measure angles and maintain absolute position between power cycles. Unlike incremental rotary encoders, which only offer two or four values in a rotation and are designed to track full rotations and direction, the Bourns Absolute Encoder measures angles, providing a more precise and accurate reading.

Package Includes:

• Absolute Contacting Encoder (ACE)
• Mounting nut and lockwasher (for a 9mm mounting hole)

Key Features:
