AK50 optical absolute encoder | Absolute Encoder

AK50 optical absolute rotary encoder

The AK50 is a 50 mm optical absolute rotary encoder designed for industrial automation, machine control, and precision positioning. Using photoelectric sensing technology, it delivers reliable absolute position feedback with up to 8-bit resolution and supports Gray code, binary code, or custom output formats to meet specific application requirements.

One of the AK50’s standout features is its programmable reference position. Users can select an arbitrary zero point through a switch, with up to 256 indexed reference positions, making machine setup faster and more flexible while simplifying calibration and commissioning.

The encoder provides accurate, repeatable position feedback and supports shaft speeds of up to 3,000 rpm without counting loss. In addition, it handles high axial and radial shaft loads, making it well suited for demanding industrial machinery and continuous operation.

Built for harsh environments, the AK50 features an IP66-rated housing, IP65 shaft protection, and operates in temperatures from -20°C to +80°C. It also offers excellent resistance to vibration, shock, and humidity, ensuring dependable performance in challenging industrial conditions.
