Contactless linear position transducer with magnetostrictive technology: the absence of electrical contact on the cursor eliminates problems of wear and consumption and guarantees almost unlimited life.
The reduced dead zones and the head’s threaded shape and small size make the RK-4 series ideal for applications requiring the installation of the transducer partially inside the hydraulic cylinder as a simplified alternative compared to the models of the IK4 series.
The overall dimensions of the sensor are among the smallest available on the market.
For the interface signal, you can choose between a start/stop interface (which allows the use of multiple cursors) and an analog interface that gives the displacement of a single cursor (available in the several ranges in Voltage or Current).
Excellent linearity, repeatability, resistance to mechanical vibrations and shocks complete the product's specifications overview.
