Product Overview

The CZ-3A04 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-3A04 series incorporates a built-in stray magnetic field reduction function to mitigate accuracy degradation from disturbed magnetic fields, alongside a dual overcurrent detection feature. Compliant with UL 61800-5-1 safety standards, it is ideal for industrial AC drives, servo motors, and for interfacing with 3.3V AD converters. The CZ-3A0x series offers a range of linear measurement capabilities, from 12.9A to 129.1A, facilitating consistent board designs across different current ratings.
