Current Sensors

We are dedicated to providing you with the highest quality products suited to your needs. 

Current Sensing is an important process for the evaluation, control, and diagnosis of electrical systems and thus are essential in many application fields. Hall Effect Current Sensors have been widely used for this purpose. They are a reliable solution for non-contact current measurement with high accuracy. The galvanic isolation between the sensor and current guarantees a high degree of safety. Furthermore, Hall Effect Current sensors have a simple structure and low energy losses.

A comprehensive introduction to Hall Effect Current Sensor you find here.

To find the Current Sensors, that fit your technical specifications the best, we highly recommend using the filter function and the product subcategories.
