The AK36 is a 36 mm optical absolute rotary encoder designed for servo motors, robotics, CNC machinery, and industrial automation. Available in single-turn and multiturn versions, it provides high-resolution position feedback, fast communication, and reliable performance in compact motion control systems.
Using optical sensing technology, the AK36 delivers up to 21-bit single-turn resolution and up to 24-bit multiturn resolution, ensuring accurate position measurement over multiple revolutions. As a result, the encoder provides instant absolute position data after power-up, eliminating the need for homing and improving machine productivity.
The encoder supports both SSI and BiSS serial communication interfaces, allowing seamless integration with PLCs, servo drives, and industrial motion controllers. Its compact 36 mm housing makes it an excellent choice for applications where installation space is limited.
Designed for demanding industrial environments, the AK36 supports shaft speeds of up to 10,000 rpm while maintaining low starting torque and low rotor inertia for smooth, responsive motion. In addition, it is available with IP54 protection as standard or IP64 protection as an option, providing dependable operation in challenging conditions.
