GRA Hall-effect single-turn rotary sensor with shaft



  • Rotary sensor for measurement ranges up to 360° with ability to program analogue versions of ±15° steps.
  • Contactless Hall technology for almost infinite sensor life due to the absence of wear on the sensing element.
  • Various configurations make the product easy to install on vehicles.
  • High IP protection level, resistance to shock and vibration, and high electromagnetic compatibility make these products suitable for many mobile hydraulics applications.
  • Developed to ensure a robust and high-performance solution for applications such as agricultural machines, construction machines, and material handling equipment.
