The HHS 5203-536 Helmholtz Coils are meticulously designed to generate highly precise magnetic fields from DC to 2 kHz, with a resonance frequency up to 13 kHz, ensuring efficient energy transfer and stable, high-quality magnetic fields for a wide range of applications. Here are the standout features and advantages:

  • Precise Magnetic Field Generation: The HHS 5203-536 excels in producing magnetic fields that maintain a strongly linear relationship to the coil current. This allows for exact field strength calculations using analytical or numerical methods based on the coils’ geometry, number of turns, and coil current.
  • Ideal for Calibration and Testing: This model is perfect for calibrating magnetic field probes or sensors and conducting immunity tests. The exact calculation of magnetic field strength ensures reliable and reproducible results.
  • High Temperature Tolerance: The coils are constructed with high temperature proof coated copper wire, enabling them to generate magnetic fields up to 42 kA/m for short durations (5 minutes).
  • Compliance with Standards: The HHS 5203-536 is suitable for magnetic immunity testing according to automotive standards or MIL-STD 461.
  • Traceable Calibration: Magnetic field calibration is directly traceable to current measurement or voltage drop across a known resistor, ensuring accuracy and reliability.
