Non-contact magnetostrictive displacement sensors are advanced devices used to measure linear position with high accuracy and reliability. They work by sending a current pulse through a magnetostrictive waveguide and detecting the interaction with a movable permanent magnet. Because the magnet does not touch the sensing element, wear is greatly reduced, making the sensor ideal for demanding industrial environments.

These sensors provide absolute position output, fast response, and excellent repeatability. They resist dust, moisture, vibration, and shock, and can operate over long distances without recalibration. Common outputs include analog, SSI, CANbus, and Profibus, allowing easy integration with PLCs and control systems.

Typical applications include hydraulic cylinders, injection molding machines, metal processing, oil and gas equipment, and automated production lines. By choosing the right stroke length, output type, and protection class, engineers can improve machine safety, precision, and uptime. Non-contact magnetostrictive displacement sensors are therefore a strong solution for modern position measurement.

The sensing element is sealed inside a durable stainless steel tube, so it can withstand high pressure and harsh conditions. The non-contact design eliminates mechanical friction, which improves long-term stability and reduces maintenance costs. With high resolution and low hysteresis, it supports precise closed-loop control in industrial automation.
