Description

Product
Hall-effect single-turn rotary position sensor GRA with shaft. Manufacturer: Gefran.

Overview
  • Non-contact Hall-effect sensing for single-turn angular measurement up to 360° (programmable ranges).
  • Shaft-mounted mechanical design suitable for direct coupling or linkage with levers and kits.
  • Multiple electrical outputs and fieldbus options for integration in industrial and mobile-hydraulic systems.


Main features
  • Linearity < ±0.5% FS
  • Operating temperature: -40 °C … +85 °C (higher ranges on request)
  • Vibration resistance: 20 g, 10 Hz … 2000 Hz (IEC 60068-2-6)
  • Shock: 50 g, 11 ms (IEC 60068-2-27)
  • Protection: IP67; IPX9K with mating connector mounted


Configurable options
  • Supply voltage: +5 Vdc (for ratiometric 0.5…4.5 V) or +9…+36 Vdc depending on output
  • Output types: 0.5…4.5 V ratiometric; 0.5…4.5 V; 0…10 V; 4…20 mA; CANopen; SAE J1939
  • Electrical connectors: AMP Superseal 6P (e.g. 282108-1) or DEUTSCH 6P (DT04-6P)
  • Circuit types: Single (S) or Redundant (R)
  • Programmable measurement windows (example analog steps ±15°; ranges up to ±180°)
  • Accessories: levers and mounting kits (e.g. LEV006, LEV007, PKIT series)


Typical applications
  • Mobile hydraulics
  • Agricultural machinery
  • Construction and earthmoving equipment
  • Material handling and lifting systems


Technical specifications
  • Model: GRA
  • Resolution: 12 bit (analog); 14 bit (CANopen/SAE J1939)
  • Maximum speed: 120 rpm
  • Thermal drift < 50 ppm/°C
  • Expected mechanical life: typ. 35 million operations (example stroke ±75°)
  • Housing material: PBT
  • Notes: Example order code and detailed variants available via configurator; no price/EAN provided
