Product Overview
The CQ-2063 is an open-type current sensor utilizing a Hall effect sensor to provide an analog voltage output proportional to AC/DC current. It features a quantum well ultra-thin film InAs Hall sensor for high-accuracy and high-speed sensing. The integrated AI-Shell package, containing the Hall sensor, magnetic core, and primary conductor, ensures space-saving design and high reliability. This bidirectional sensor offers electrical isolation between the primary conductor and the sensor signal, operates on a single 5V supply, and provides a ratiometric output. It is designed for low variation and low temperature drift of sensitivity and offset voltage, with low noise output and a fast response time. The device is housed in a small-sized, halogen-free package.
