The AD58 multi-turn absolute encoder is an optical encoder with a multi-turn gear and optical scanning. The mechanical concept is based on a shaft assembly mounted in dual ball-bearings with a flexible torque support. As a result, these encoders are suitable for incorporating in BLDC servo motors and such demanding applications as CNC, precision positioning and high-resolution printing. The encoder is available with resolutions of up to 22 bits single-turn and 12 bits multi-turn.
