Linear Position Sensor

The R-Series magnetostrictive position sensor includes diagnostic LEDs and external programming capabilities.


It is available with analog and digital serial outputs for noncontact sensing in linear and absolute measurements. Red and green LED indicators on the sensor may be monitored for errors such as magnet not detected, missing external interrogation signals, insufficient or out-of-range input power, and other maintenance issues. Advanced R-Series electronics provide accuracy, EMI immunity, and signal-to-noise performance in harsh electrical environments. Users can expect sensing resolutions as low as 1 m m with an output linearity below ±0.01% and repeatability below ±0.001% of full scale. Reverse polarity and overvoltage protection to 36 Vdc minimizes failure from miswiring. Shock and vibration resistance are 100g and 25g/10-2,000 Hz, respectively, for demanding motion-control applications. In addition, in-line pushbutton or PC software programming is possible using a simple serial communications link. Monitoring can take place remotely via the PC user-interface software.
