Contactless linear position transducer with HYPERWAVE magnetostrictive technology with RS422-SSI digital output interface. Housing closure with removable ring nut to allow the whole electronics and sensing element replacement. The absence of electrical contact on the cursor eliminates all wear and guarantees almost unlimited life. High accuracy of the mesurement with reference to the non linearity, repeatability and hysteresis. High resistance to vibrations, mechanical shocks for use in a harsh industrial environment.
