OTT-JAKOB MSU Sensor System

The OTT-JAKOB MSU Sensor System is an integrated, sensor-based assistance solution designed to enhance machine tool availability and efficiency. By consolidating three critical monitoring functions into a single unit, the MSU ensures precise control over the clamping process, enabling predictive maintenance and reducing unplanned downtime.

Key Features

• Integrated Drawbar Position Monitoring | Utilizes an electronic distance measurement system to accurately detect the drawbar shaft's position, identifying clamping statuses: "Unclamped," "Tool Clamped," and "Clamped without Tool."
• Piston Position Detection | Monitors the unclamping unit piston's position to prevent contact with rotating machine elements, ensuring safe operation.
• Optional Leakage Detection | Employs a calorimetric sensor to measure leakage flow in rotary unions, triggering alerts when predefined flow limits are exceeded, thus protecting the spindle from potential flooding. 
• Compact and Flexible Design | Sensors and evaluation electronics are pre-assembled within the unclamping unit, allowing integration into various OTT-JAKOB unclamping units and adaptation to special solutions. 
• Wear-Free Operation | Incorporates inductive sensors for monitoring, ensuring durability and reducing maintenance needs.
• Versatile Data Utilization | Collected measurement data can be used for statistical analyses, such as tracking the number of tool changes, and supports the integration of additional sensors like temperature sensors or strain gauges.

The standard MSU Sensor System integrates essential monitoring functions into OTT-JAKOB unclamping units. It includes drawbar position monitoring and piston position detection, with optional leakage detection. This configuration is ideal for applications requiring reliable clamping status verification and basic condition monitoring.

Key Features

• Drawbar Position Monitoring | Ensures accurate detection of clamping statuses to prevent operational errors.
• Piston Position Detection | Prevents mechanical interference by monitoring piston positions during machining.
• Optional Leakage Detection | Provides early warning of potential spindle flooding due to rotary union leaks.
  
  

An advanced iteration of the MSU, the IO-Link Compact version offers enhanced communication capabilities and a more compact design. It combines a hydraulic unclamping unit with integrated clamping status sensor technology and a single-passage rotary union with permanently closed sealing surfaces. This configuration supports modern automation structures with minimal engineering effort.

Key Features

• IO-Link Compatibility | Facilitates seamless integration into smart factory environments, enabling efficient data exchange and system diagnostics.
• Ultra-Compact Design | Combines multiple components into a single, space-saving unit, suitable for applications with limited installation space.
• Enhanced Monitoring Capabilities | In addition to standard functions, it allows for monitoring of temperature, stroke, and leakage, providing comprehensive condition data.

This diagram illustrates the OTT-JAKOB MSU Sensor System integrated within the unclamping unit of a machine tool spindle. It highlights key monitoring functions: drawbar position detection for precise clamping status, piston position monitoring for safe operation, and optional leakage detection to protect against spindle flooding. Compact and fully integrated, the MSU ensures safe, reliable clamping processes and supports predictive maintenance.
