RK-5 MH contactless – Magnetostrictive – ROD flange AISI 316 – Analogues outputs



  • Linear position transducer with GEFRAN’S innovative ONDA magnetostrictive technology for long life.
  • The absence of electrical contact on the cursor eliminates wear and guarantees almost unlimited life.
  • Gefran’s patented ONDA technology achieves a compact, modular structure for simple installation.
  • RK-5 is a magnetostrictive position transducer with a flanged connection that installs completely inside oil-pressure cylinders.
  • Its unique design, plus a wide range of cursor configurations, ensures easy installation and total compatibility with cylinder manufacturer specifications.
  • Working temperature from -40 to +105°C, working pressures up to 350 bar, high resistance to vibration (25 g), and shock (100g) give the sensor the indispensable strength needed for heavy-duty use (for example mobile hydraulics).
  • High performance in terms of transduction of measurement defined as linearity, hysteresis, and repeatability.
  • The signal is analog in models with current or voltage output.
