Magnetec offers customers design support to ensure they get the best and most cost-effective solutions for their specific applications.


Various designs with the same electrical performance allow customers to use MAGNETEC’s Fluxgate-Based Residual Current Sensors in different products without additional development costs.


MAGBLUE SERIES Residual Current Sensor element

The Fluxgate-Based Residual Current Sensors are made of an induction coil with particular characteristics. It has a high permeability Nanoperm® core, which makes the detection of very low (6mA) DC currents possible. The core material has very high permeability and low remanence (Hc), enabling a very fast transition between linear and saturated states. Energizing the coil with an alternating voltage makes the core go through a complete hysteresis loop. With a residual current flowing through the coil, the hysteresis loop is shifted. The measurement of this shift represents the primary current.


It enables the use of individual and customized evaluation circuits, allowing an ideal system integration into your application in a cost-efficient way.


SAFEBLUE® SERIESResidual Current Sensor for EV Charging

MAGNETEC offers AC/DC sensitive residual current sensors for charging cable (mode 2), AC wallbox (mode 3), DC charging station (mode 4), and optional in on-board charger applications. The SafeBlue® series Sensors feature a high permeability Nanoperm® core, which makes the detection of very low (6mA) DC currents possible. It has an integrated evaluation circuit, providing all features requested by the relevant standards.


MAGNETEC sensors are already in use at numerous automotive OEMs. MAGNETEC would be happy to develop your individual product for you now.
