Hall sensors – non-contact and wear-free detection

• Reliable detection of rotating gear wheels
  • High switching frequency of up to 20 kHz
  • High resolution ensures reliable gear detection upward a module size of merely 1
• Detection of the rotational direction
  • Two phase-shifted signals
  • Compliant to the strict railway standards
• Wear down to a minimum for maximum service life
  • Non-contact sensing principle
  • WiNo moving parts
• Especially for harsh environmental conditions
  • Robust all-metal housing
  • Extensive temperature range and high pressure resistance
  • For use contaminated, damp or oily environments

Hall sensors identify ferromagnetic objects by the non-contact sensing principle. Achieving very high switching frequencies, they are ideal to reliably detect speed and rapidly changing rotational directions at moving gears.
