Current sensor connects directly to busbars to drive miniaturisation

Described as easy to install, the HCME current sensor series has a compact design and can be directly mounted on busbars, says Harting.

The HCME current sensor series contributes to shorter installation and an easy pre-assembling of power electronics, adds the company.

Despite the limited space requirements, the dimensions of the devices are 60mm in height and 140mm wide. The HCME current sensors measure high currents up to 5500A with highly reliable precision. This makes the sensors suitable for present day power electronics, characterised by their strong modular and compact design.

The HCME sensors use the open-loop measurement principle. This provides a direct representation of the primary current with an accuracy of up to ±  one per cent. The HCME sensors can measure direct or alternating currents, even if they have complex waveform, over a frequency range from 0 to 50kHz. The high immunity to interferences, e.g. caused by the magnetic fields of external current-carrying conductors, constitutes a specific benefit, adds Harting.

The wide temperature range from -40 to +85 degree C enables the deployment under extreme environmental conditions. The sensors come in standard sizes and their compact design offers a high degree of freedom for integration into individual applications.

The sensors are reliable and accurate, says Harting, making them suitable for use in PV inverters, frequency converters or power supplies for welding applications.

The Harting Technology Group provides industrial connection technology for the Data, Signal and Power. The group has 13 production plants and branches in 44 countries. Harting also produces retail checkout systems, electromagnetic actuators for automotive and industrial series use, charging equipment for electric vehicles, as well as hardware and software for customers and applications in automation technology, mechanical and plant engineering, robotics and transportation engineering.
