AK58 optical absolute encoder

Ø58mm AK58 Absolute Encoder Series

The AK58 series offers high-precision photoelectric absolute encoders in Ø58mm format, available in six models: AK58M, AK58B, AK58C, AK58C2, AK58C3, and AK58D.

These encoders support SSI and BiSS serial interfaces, delivering up to 21-bit single-turn and 24-bit multi-turn resolution with binary or Gray code output, making them ideal for industrial automation, robotics, and motion control applications.

Key Features:

  • Ø58mm absolute single-turn and multi-turn encoders

  • SSI and BiSS serial interfaces

  • Up to 21-bit single-turn and 24-bit multi-turn resolution

  • Binary or Gray code output for flexible integration
