HHS 5206 – Circular Helmholtz Coils
HHS 5206-132 – Circular Helmholtz Coils with 132 turns
The Schwarzbeck HHS 5206-132 Circular Helmholtz Coils are specially designed to generate precise magnetic fields from DC up to 30 kHz, with a resonance frequency exceeding 50 kHz. Featuring 132 turns, these coils offer superior performance with a maximum magnetic field strength of 4713 A/m for short durations and 3142 A/m continuously. This model stands out for its high number of turns, which allows for more precise control and stronger magnetic fields compared to other models.

The HHS 5206-132 is ideal for calibrating magnetic field probes and sensors, as well as conducting magnetic immunity testing according to automotive standards and MIL-STD 461. Its high temperature-proof Teflon-coated wire ensures durability and reliability in demanding testing environments. The strong linear relationship between coil current and magnetic field strength allows for exact field strength calculations using analytical or numerical methods based on the coil’s geometry and current.

With a coil diameter of 600 mm and the capability to accommodate a maximum cubic Device Under Test (DuT) size of 32.5 x 32.5 x 32.5 cm, these coils are versatile for various testing setups. The HHS 5206-132 features 4 mm banana jacks and screw terminals for secure connections. Special care should be taken by individuals with magnetic-field-sensitive implants, such as pacemakers, when using this device.

The easy installation process and robust design make the HHS 5206-132 an excellent choice for high-precision magnetic field generation and calibration.
