The Midi Ultra IncOder™ is a premium non-contact high-accuracy inductive ring encoder designed for precision angular measurement in harsh industrial, aerospace, robotics, and defense environments. Factory calibrated and supplied with an individual accuracy certificate, each encoder delivers exceptional positioning performance while maintaining the durability required for demanding applications.
Available in multiple diameters and configurable mechanical, electrical, communication, and resolution options, the Midi Ultra IncOder offers outstanding flexibility for OEMs and system designers. Depending on the encoder size, the Ultra IncOder Series achieves accuracy as high as 19 arc-seconds, making it ideal for high-performance motion control systems where precision and reliability are essential.
Its contactless inductive sensing technology eliminates wear while providing excellent resistance to dust, oil, vibration, moisture, and electromagnetic interference. Unlike optical encoders, the Midi Ultra IncOder continues to deliver accurate position feedback in environments where contamination would compromise traditional sensing technologies.
The encoder supports single-turn resolutions up to 21 bits and optional multiturn functionality with BiSS-C, SPI, SSI, and asynchronous serial communication protocols, making it suitable for advanced servo systems, rotary tables, robotics, semiconductor equipment, and precision automation.
