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. As the authorised distributor of Germanjet in China, Yice Electric provides local selection advice, technical support, spare parts delivery and after-sales response, following the project from the design stage right through to on-site commissioning.

Industry Insights
SSI jumps after a longer cable: drop the clock to match the length
162 and 192 share one table: longer cable, lower maximum rate; minimum clock spacing 48 μs. Occasional huge numbers — drop the clock first. Patterned jumps — check Gray versus binary.
Analogue reading at zero: end of stroke, or a broken wire?
On 4-20 mA the start of stroke is still about 4 mA; a broken loop falls near 0. On 0-10 V, 0 V cannot tell zero from an open cable. Check the lamp, then measure at the sensor — do not swap the rod first.
Serial Fieldbuses for Position Feedback: CANopen vs Profibus
Serial fieldbuses include 194 CANopen and 195 Profibus DP. CAN’s physical layer is not RS-485. Compare the trade-offs, then follow the master.
