Compact, High-Resolution Interpolator for Position Feedback in Rolling Mill and Industrial Applications

The Magnescale MD20B Interpolator is a compact, high-performance signal processing unit designed for precise position control in industrial environments. Compatible with the SR721-SP series, this interpolator is ideal for applications requiring accurate feedback to NC units and display systems in rolling mills and other high-precision machinery.

This unit generates both A/B quadrature signals and Up/Down signals, making it suitable for integration with a wide range of control systems. It also includes a zero point signal and alarm signal output, all transmitted via a differential line driver for noise-resistant communication.

With the optional PU20 power supply unit, power for up to 3 axes can be supplied.
A/B quadrature signal, up/down signal, zero point signal and alarm signal output by differential line driver.
It can be use as successor model of MD20A.

Resolution

0,1 µm / 0,2 µm / 0,5 µm / 1,0 µm / 2,0 µm / 2,5 µm / 4,0 µm / 5,0 µm / 10,0 µm selectable

About

One of the standout features of the MD20B is its selectable resolution, offering a range from 0.1 µm to 10.0 µm. This flexibility allows users to tailor the system to their specific accuracy and speed requirements. At its highest resolution of 0.1 µm, the MD20B supports a response speed of up to 42 m/min, ensuring reliable performance even in fast-moving production environments.

The interpolator operates on a 5V power supply, and when paired with the optional PU20 power supply unit, it can support up to three axes simultaneously. This makes it a scalable solution for multi-axis systems and compact installations.

Designed as a successor to the MD20A, the MD20B offers improved performance and compatibility while maintaining a familiar interface for existing users. Its robust design and reliable signal output make it a trusted choice for rolling mill automation, metal processing, and precision motion control.
