Magnetostrictive Sensor MRG
Non-contact linear displacement transducer based on magnetostrictive technology, designed for harsh use in industrial environments. Non-contact and thus wear-free operation with unlimited mechanical life.
Different analogue output signals available with direct or inverted signal, thus high flexibility in application with simultaneously very good measuring accuracy in terms of non-linearity, repeatability and hysteresis.
- Nominal stroke from 150 ... 1500mm
- High resolution of less than 1µm
- Non-contact, wear-free operation
- High signal strength and very good signal stability
- Shock resistant / Schick tested up to 100g
- Robust stainless steel housing, protection class IP67
- Compatible with sensors from BALLUFF and MTS
