Position sensor manufacturer ASM has introduced an IP67 magnetostrictive noncontact position sensor featuring absolute position output.

Position sensor manufacturer ASM has introduced an IP67 magnetostrictive noncontact position sensor featuring absolute position output The Posichron sensor consists of an easily mounted profile containing a magnetostrictive wire, and a noncontacting magnet which is suspended above the profile and moves along the length of the profile

In normal operation the magnet is attached to a machine tool or hydraulic cylinder etc and the profile containing the magnetostrictive wire is attached to a fixed point.

Making good use of the Wiedemann effect, the interaction of a current pulse in the wire in the proximity of the position magnet generates a sonic pulse which travels down the wire and is processed by the pickup element to give a voltage output relative to the magnet position.

The sensor is robust and fast, has high resistance to dust, moisture and many fluids, has ultralow hysteresis and is available with 0-10V or 4-20mA output.
