Current sensor AKM CZ3AG7 featuring dual overcurrent detection and low heat generation for continuous

Product Overview

The CZ-3AG7 is an open-type current sensor utilizing Hall effect technology to provide an analog voltage output proportional to AC/DC current. Engineered with a Group III-V semiconductor thin film Hall sensor, it delivers high accuracy and high-speed current sensing. Its coreless, ultra-small surface mount package ensures space-saving integration, while the low primary conductor resistance minimizes heat generation, enabling a continuous current rating of 50Arms. The CZ-3AGx series features a built-in stray magnetic field reduction function to mitigate accuracy degradation from disturbed magnetic fields and includes a dual overcurrent detection function. Compliant with UL 61800-5-1 safety standards, it is ideal for industrial AC drives, servo motors, and applications requiring input into a 3V AD converter. The series offers a range of linear sensing capabilities, from 11.6A to 116.6A, facilitating consistent board design across different current ratings.
