View product detailsHow Magnetostriction Works
Non-contact measurement by design: the principle itself delivers no wear, long service life and exceptional stability. Two magnetic fields interact to launch a strain wave, and a microprocessor resolves it into an absolute position.
Two magnetic fields
The moving position magnet produces the first magnetic field and the pulse generator the second; both coexist along the waveguide.
Strain wave launched
At their point of intersection the two fields interact and launch a torsional strain wave that travels along the waveguide.
Wave detection
The wave analyser captures the returning echo; its propagation delay is strictly proportional to the magnet position.
Precise resolution
An embedded microprocessor analyses the waveform, converts it into absolute position and outputs a standard industrial signal.
Core Advantages
Non-contact measurement means minimal wear, long-term stability and very low maintenance cost.
Non-contact measurement
With the magnetostrictive waveguide principle there is no mechanical contact between the position magnet and the sensor body, eliminating frictional wear at its source. With no moving parts inside, service life under normal duty is extremely long, and the maintenance burden of mechanical drift and periodic replacement is greatly reduced.
Non-contact · Long service lifeμm-level accuracy
Repeatable resolution down to 1 μm with non-linearity of ±0.02% F.S., held stable over the full cylinder stroke. Temperature drift is kept within ±15 ppm/°C, so whether it is the precision closed loop of an injection cylinder or roll gap positioning on a mill, μm-level control requirements are met.
±0.02% F.S. · 1 μm resolutionHigh protection class
A fully sealed stainless steel housing, with standard models rated IP67 dust-tight and water-resistant; the dedicated mobile hydraulics series (Series 13) reaches IP68 and can operate permanently submerged; IP69K connectors are available for high-pressure washdown. Oil, dust, coolant, pressure washers — however harsh the site, it copes.
IP68 / IP69K · Stainless steel housingMultiple output signals
Analog outputs (4–20 mA / 0–10 V / Start-Stop) are plug-and-play with the vast majority of PLCs and controllers; digital interfaces cover SSI, PWM, CANopen, Profibus DP, Profinet, EtherCAT and other mainstream industrial fieldbuses. One sensor fits control systems from Siemens, Mitsubishi, Omron, Beckhoff and more.
CANopen · EtherCAT · ProfibusLow total cost of ownership
The non-contact principle means no periodic recalibration is required — calibrate once at installation and run for years. Compared with contact-type measurement, non-contact magnetostrictive technology significantly reduces long-term maintenance frequency and overall operating cost.
Maintenance-free · Low operating costGerman technology, local support
Built on more than thirty years of German magnetostrictive measurement expertise, the products are CE certified and RoHS compliant.

Industry Insights
Don't Touch the Magnetostrictive Displacement Sensor Yet: Four Layers to Check in Order
When sync drifts out, the two most convenient actions on site are changing control parameters and swapping the magnetostrictive displacement sensor. Both are usually wasted effort. The correct order is bottom-up through four layers: mechanical backlash and distortion, then hydraulic split, leakage, oil temperature and trapped air, then mounting and calibration of the position feedback, and only then control parameters. A ten-minute static versus dynamic split narrows the direction first.
Mechanical, Divider Valve or Servo Closed Loop: Choosing Between Three Ways to Sync Cylinders
Every multi-cylinder sync scheme reduces to one of three: enforce it with structure, split the flow, or close a loop on position. All three work, in different territory. Mechanical sync is easiest when spans are short and strokes are small, a divider valve is enough when the load is symmetric and the tolerance loose, and servo closed loop becomes unavoidable once the load is asymmetric or the tolerance reaches a few parts in a thousand. A three-step test decides which applies.
Why One Divider Valve Cannot Keep Two Cylinders Together: Four Errors Open Loop Never Corrects
Two cylinders push the same beam. The command is identical, the valves are identical, and the beam still runs crooked. The problem is not tuning. A divider valve synchronises by splitting flow, and with no position value anywhere in the circuit four errors stay uncorrected: the flow split itself, flow shifting under asymmetric load, oil compressibility, and internal leakage plus oil temperature drift. The position difference keeps accumulating along the stroke until something else stops it.
