Coreless current sensor AKM CZ3AG1 with analog voltage output and dual overcurrent detection function

Product Overview

The CZ-3AG1 is an open-type, coreless current sensor utilizing Hall sensors to provide an analog voltage output proportional to AC/DC current. It features high accuracy and high-speed sensing due to its Group III-V semiconductor thin film Hall sensor. The ultra-small, surface-mount package offers space-saving benefits, while its low primary conductor resistance minimizes heat generation, enabling a continuous current of 50Arms. The CZ-3AGx series incorporates a built-in stray magnetic field reduction function to counteract accuracy degradation from disturbed magnetic fields and a dual overcurrent detection function. It is UL 61800-5-1 safety compliant and suitable for industrial AC drives, servo motors, and interfacing with 3V AD converters. The series offers a range of linear sensing capabilities, from 11.6A (CZ-3AG1) to 116.6A, allowing for consistent board designs across different current ratings.
