High-Speed, High-Frequency Applications Empowered by Non Contact Displacement Sensors

Soway offers a comprehensive range of Magnetostrictive Displacement Sensors, including models such as the SDM20T, SDM21T, SDM22T, SDM23T, and SDM40S. These advanced non-contact sensors are specifically designed to meet the demands of high-speed and high-frequency applications. They provide unparalleled reliability, performance, and longevity, making them ideal for a wide array of industrial environments. Whether you need precise displacement measurement in manufacturing, automotive, aerospace, or any other demanding industry, Soway's sensors are optimized to deliver exceptional results.

Unlike traditional contact-based sensors, non contact displacement sensors operate without any physical connection between the moving part and the sensing element. This design eliminates friction, mechanical wear, and the risk of signal degradation due to contact fatigue. In magnetostrictive variants position detection is achieved through the interaction between a moving magnetic cursor and a magnetostrictive waveguide. The sensor captures the location based on the time-of-flight of a torsional wave, providing high-resolution, real-time displacement measurements.

Why Non Contact Displacement Sensors Excel in High-Speed Environments

1. Zero Mechanical Wear = Continuous Operation

High-speed industrial systems often run continuously for long durations. Any sensor that requires physical contact is prone to degradation over time. Non-contact designs eliminate mechanical friction, making them ideal for systems requiring 24/7 uptime.

2. Fast Response Time

In high-frequency control loops—such as those found in CNC machinery, injection molding machines, or servo-driven systems—response speed is critical. Magnetostrictive sensors from Soway provide microsecond-level response with no signal delay, ensuring real-time feedback even in the fastest automation cycles.

3. High Vibration and Shock Resistance

Rapid movement often generates mechanical shocks and vibrations. Contact sensors may lose calibration or fail under such conditions. Non contact displacement sensors maintain stable readings even under dynamic conditions, enabling them to withstand aggressive mechanical environments.

4. Outstanding Repeatability and Precision

Precision at high speeds is challenging, but essential in sectors like robotics, metalworking, and electronics manufacturing. Soway’s non contact sensors offer repeatability in the micron range, ensuring that high-frequency operations remain consistently accurate with no signal drift.
