Product Overview

The CQ-2333 is an open-type, high-speed current sensor designed for AC/DC current measurement. Utilizing a quantum well ultra-thin film InAs Hall sensor, it offers high accuracy and fast response times. Its integrated AI-Shell package, containing the Hall sensor, magnetic core, and primary conductor, ensures space-saving design and high reliability. The sensor provides an analog voltage output proportional to the measured current, featuring electrical isolation between the primary conductor and the sensor signal. It operates on a single 5V supply and is suitable for applications requiring precise and rapid current sensing.
