Gearwheel sensors

• Reliable detection of rotating gearwheels
  • High switching frequency up to 20 kHz
  • The high resolution allows for reliable gear detection down to from module size 1
• Detection of sense of rotation
  • Two phase-shifted signals
  • Comply with strict railway standards
• Minimized wear at maximum service life
  • Non-contact detection
  • Without moving parts
• For particularly harsh ambient conditions
  • Robust all-metal housing
  • Extensive operating temperature range and high pressure resistance
  • For use in contaminated, damp or oily environments

Hall sensors operate on non-contact sensing of ferromagnetic objects. Thanks to very high switching frequencies they are often used for tooth detection on fast rotating gearwheels.
