Hall sensors – Contactless and wear-free detection

Bare your teeth by monitoring of rotational, speed monitoring and acquisition of part location

Thanks to their high switching frequency of up to 20 kHz, Hall sensors are preferred for the detection of rapidly rotating gear wheels. On account of their high resolution, gears can be reliably detected from a module size of only 1 upwards.

Thanks to two phase-shifted signals, they can detect not only speed but also rotational direction. Special versions have been developed specially for detecting the rotational speed of rail vehicles, for example to prevent the wheels from slipping or blocking. They meet the strict railway standards and guarantee a high degree of safety.

Since Hall sensors do not have any moving mechanical elements whatsoever, wear is reduced to a minimum and service life is extended considerably. In their fully enclosed metal housings, our Hall sensors are ideal for use in dirty, damp or oily environments.

  • Areas of application
    • Slide control and speed monitoring at railed vehicles

      • Consistent speed feedback prevents the wheels slipping and locking
      • Dependable operation by extreme immunity to shocks and vibrations
      • Top safety level by compliance with strict railway standards


      Speed monitoring at ring spinning machines

      • The high switching frequency allows for highly dynamic applications
      • Dependable detection in any environment thanks to extreme dirt resistance
      • Wearfree and ultra-long service life by non-contact Hall technology


      Directly integrated in the gear

      • Dependable feedback of speed and rotational direction of toothed wheels
      • Sensor face can also be deployed in oil
      • Extended temperature range and pressure resistance for a wide application range
    General information

    Hall sensors identify ferromagnetic objects by the non-contact sensing principle. Achieving very high switching frequencies, they are ideal for gear applications where rotating speeds and directions of rapidly turning toothed wheels must be reliably detected.

    Special properties
      • Contactless detection
      • Wide temperature range, high pressure resistance
      • Very high detection speeds (up to 20,000 measurements per second)
      • Wear-free, since there are no moving mechanical elements
      • Robust housing made entirely of metal
