1 or 2 channel speed sensor GEL 2471


Sensor for electrically conductive measuring scales

  • Up to 4 mm air gap
  • Maintenance- and wear-free operation due to non-contact measurement of rotation
  • Weight-saving construction due to light-weight target wheels made of e.g. aluminium
  • Reinforced walls in the sensor tube with a diameter of 20 mm provide increased protection against the impact of stones, grit and foreign objects
