Product Overview

The CQ-2092 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 includes the Hall sensor, magnetic core, and primary conductor, enabling a space-saving and highly reliable solution. 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 in sensitivity and offset voltage, with low noise output (2.1mVrms max.) and a fast response time of 1s (typ.). The device comes in a small-sized surface mount package and is halogen-free.
