CO-10-SF

10[mm] Clamp-On Non-Intrusive Magnetic Field Concentrator

The CO-10-SF magnetic field concentrator, is designed for non-intrusive and isolated measurement of electric currents. Thanks to the Clamp-On design, the contact- less current sensor can be safely installed without the need to interrupt or cut the cable.

Description

The CO-10-SF comprises a soft ferromagnetic shield featuring superior material characteristics such as high linearity and very low hysteresis. Applications include DC and AC current sensing up to 30 kHz, motor control, battery monitoring, charge control, white goods,and many more.

CO-10-SF can be paired with any planar magnetic field sensor such as Melexis IMC-Hall® or any GMR/TMR sensor, to create an open loop current measurement system able to measure currents up to ±200 A.

Thanks to its hollow bottom design, CO-10-SF enables the direct housing of a planar current sensor and its capacitors underneath, thus allowing for a compact and space-saving solution.

CO-10-SF can be directly soldered to the PCB thanks to its 4 through-hole pins, granting a robust and secure hold.
