Output of current crane rotary angle

  • Reliable position sensing even in case of a power failure thanks to absolute operating principle
  • Vibrations and strong crane forces do not affect the sensor thanks to contactless operation
  • Easy integration even in very limited spaces because the electronic assembly is completely integrated in the sensor housing
Technology
Analog magnetic rotary sensors – Technology

The rotary encoders detect the rotary angle of a permanent magnet in relation to the sensor and convert the angular information into an analog electric output signal.
