Product Overview
The CQ-2093 is an open-type current sensor that utilizes a quantum well ultra-thin film InAs Hall sensor to provide high-accuracy and high-speed AC/DC current sensing. Its analog voltage output is directly proportional to the measured current. The integrated AI-Shell package combines the Hall sensor, magnetic core, and primary conductor, offering a space-saving and highly reliable solution. Key features include bidirectional measurement, electrical isolation, 5V single supply operation, ratiometric output, low variation in sensitivity and offset voltage, low temperature drift, low noise output, and a fast response time, all within a small-sized surface mount, halogen-free package.
