High current compatible compact/thin current sensor "CZ375x series"

High current compatible compact/thin current sensor "CZ375x series"

Achieving miniaturization of EV charging stations and increasing output capacity! Coreless current sensor capable of detecting ±225A with surface mount.

The CZ375x is a magnetic coreless current sensor that incorporates Hall elements. By using high-sensitivity Hall elements, it can accurately measure a wide current range of ±115A to ±225A, which is difficult to achieve with typical coreless current sensors. Continuous current flow is also possible up to 100Arms. Therefore, it contributes to "increased output capacity." Additionally, compared to shunt resistors and core-type through-hole sensors, it can contribute to "miniaturization" and "reduction of manufacturing costs." ■ Miniaturization - Due to its small size and surface-mount package, it can be mounted on the back side of the circuit board. - The primary conductor has low resistance (0.27mΩ), which suppresses heat generation, allowing it to be placed in limited space on the circuit board. * It generates one-third the heat of other companies' coreless current sensors (based on our comparative test data). ■ Reduction of manufacturing costs It contributes to reduced manufacturing (assembly) costs by eliminating the need for wire connections to through holes. * For more details, please refer to the PDF document or feel free to contact us.
