Hall-effect current sensors cover range from 100 A to 800 A.


Harting has introduced a range of Hall-effect current sensors with a current range from 100 A to 800 A. The new HCSE (Hall-effect current sensors Eco) family consists of four models, and are based on the open-loop measurement principle which provides a direct representation of the primary current with an accuracy of up to ±1%.

The HCSE sensors can measure direct or alternating currents, including signals with complex waveforms, over a frequency range from 0 to 50 kHz. Because the devices use proven Hall-effect technology to sense the magnetic field created by the current flowing in a conductor, they provide non-contact, galvanically isolated measurements with high immunity to interference from the magnetic fields of external current-carrying conductors.

The wide temperature range of -25° to +85°C allows use in thermally critical applications. The sensors come in standard sizes and their compact, unified shape across the whole product range offers a high degree of freedom for integration into individual applications.

Thanks to their high reliability and accuracy, the new sensors are ideal for application such as power supplies for welding equipment, rectifiers for direct current drives or uninterruptible power supplies.
