Bourns Absolute Encoder 絕對編碼器 (EAW0J-B24-AE0128L (COM-15036)

DESCRIPTION
The Bourns Absolute Encoder is a digital control knob that provides 128 unique results evenly spaced around a full circle. It is designed as a control panel knob but can be adapted for other uses. This can be a good alternative to using a potentiometer and analog pin, as this allows for full-turn and multi-turn operation.
It differs from the more common incremental rotary encoder which has only two or four values in a rotation and is designed to measure full rotations and direction. This measures angles and absolute position is maintained between power cycles.
