RK-5 C

Main features & Overview


Linear position transducer with GEFRAN’S innovative ONDA magnetostrictive technology for long life.

The absence of electrical contact on the cursor eliminates wearing and guarantees almost unlimited life.

Gefran’s patented ONDA technology achieves a compact, modular structure for simple installation.

RK-5 is a magnetostrictive position transdu-cer with 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 speci-fications.

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, hystersis and repeatability.

The communication system of CAN bus allows a fast and safe transmission.

The implementation of the CANopen DS-301 protocol and Device Profile DS-406 provides quick and easy integration of the transducer in the control system and automation.
