Paragraf™ GHS Series Hall effect sensors deliver the unique properties of graphene into magnetic field sensing applications.

Achieve simple yet ultra-high resolution magnetic field measurement and positioning under a wide range of operating conditions.

Paragraf’s contamination-free direct-to-wafer deposition technology enables high purity graphene, with a high carrier mobility, to be integrated into sensing technologies.

Benefits of graphene Hall effect sensors include:

  • Immunity to in-plane stray fields leading to significantly lower shielding requirements
  • High sensitivity and low noise
  • Robust with no hysteresis and no saturation in output
  • Operational at mK with extremely low heat load
  • Can be used from μT up to 30T

The GHS series of analogue sensors is designed to provide very high-performance measurement, sensing and control for e-mobility, scientific research, battery, healthcare, aerospace, industrial and automotive applications, including:

  • High precision position, rotation, torque and speed sensing
  • Accurate operation under magnetic and temperature extremes
  • Precision magnetic field measurement
  • Accurate field gradient mapping and alignment
  • High sensitivity current and power measurement
  • Continuous ultra-low power sensing

Two graphene Hall effect sensor ranges are currently available:

GHS10AT icon

GHS-A ambient range for optimal performance under ambient conditions in applications such as e-mobility, local current density analysis and mapping of battery cells.

GHS09CC icon

GHS-C cryogenic range for ultra-high-resolution magnetic field measurements under operational extremes of temperature and field range.


Paragraf also produce a kit for simultaneous data collection from up to 8 GHS sensors (GHS-C or GHS-A) – the
GHS Array Starter Kit
