High-Speed, Multi-Axis Feedback Control for Rolling Mill and Industrial Measurement Systems

The Magnescale MD50 Series interpolators — including the MD50-2N (2-channel) and MD50-4N (4-channel) models — are advanced feedback control systems designed for high-precision measurement in demanding industrial environments. Engineered for seamless integration with HA-705LK reader heads and MSS-976R scale rods, the MD50 series delivers exceptional accuracy, speed, and reliability in rolling mill applications and beyond.

Key features

High-Speed Response: Supports scale response speeds up to 100 m/min, ideal for fast-moving rolling processes.
Ultra-Fine Resolution: Selectable resolutions from 0.5µm to 10µm, with output pulse widths from 0.1 to 4.0µs.
Multi-Axis Capability: Supports up to 4 independent axes, with modular card-based architecture for easy maintenance and cost-effective repairs.
Global Compatibility: Operates on AC 100–240V, suitable for worldwide installations.
Advanced Alarm System: Dual alarm outputs (digital and analog) for real-time system monitoring and predictive maintenance.
Flexible Output Options: Standard A/B signal or Up/Down signal output for integration with various control systems.

With maximum response speed 100m/min to comply with shocks of rolled material.

Connectable to the HA705LK series reader head and MSS976R series scale.

About

Built for seamless integration with HA-705LK reader heads and MSS-976R scale rods, the MD50 Series delivers exceptional accuracy and speed. It supports scale response speeds of up to 100 m/min, making it suitable for high-speed operations where precision cannot be compromised.

The MD50 Series offers selectable resolutions ranging from 0.5µm to 10µm, with output pulse widths between 0.1 and 4.0µs. This flexibility allows users to tailor the system to their specific application requirements, whether for fine positioning or broader industrial feedback control.

Each interpolator supports 2 or 4 independent axes, depending on the model, and features a modular card-based architecture. This design not only simplifies installation but also makes maintenance more efficient — if one axis fails, only the corresponding card needs to be replaced, minimizing downtime and cost.

The MD50 is equipped with dual alarm outputs (digital and analog), providing real-time system monitoring and early fault detection. This enhances operational safety and supports predictive maintenance strategies, especially in mission-critical environments.

With universal AC input (100–240V), the MD50 Series is globally compatible and can be easily integrated into existing control racks or custom automation systems. Output options include both A/B signal and Up/Down signal, ensuring compatibility with a wide range of industrial controllers and PLCs.

This interpolator is particularly well-suited for use in steel and aluminium rolling mills, non-ferrous metal processing, and high-vibration environments where robust, high-resolution feedback is essential.

Compatible with:
- HA-705LK Reader Head (IP67, shock/vibration resistant)
- MSS-976R Scale Rod (±3µm accuracy, up to 700mm length)
Ideal for:
- Rolling mills (steel, aluminum, non-ferrous)
- Custom automation racks
- High-vibration, high-speed industrial environments

Maintenance-Friendly Design:

Each axis is independently controlled via a card-type detector board (A-1A06-661-1, MSD-MS82) (A-1A13-495-1, MSD-MS158). If one axis fails, only the affected board needs replacement — reducing downtime and service costs.
