Open loop type current sensor. High-accuracy and high-speed current sensing.
CQ-209B is an open-type current sensor using a Hall sensor which outputs the analog
voltage proportional to the AC/DC current. Quantum well ultra-thin film InAs (Indium
Arsenide) is used as the Hall sensor, which enables the high-accuracy and high-speed
current sensing. Simple AI-Shell package with the Hall sensor, magnetic core, and
primary conductor realizes the space-saving and high reliability.
■ Unidirectional type
■ Electrical isolation between the primary conductor and the sensor signal

■ Ratiometric output
■ Low variation and low temperature drift of sensitivity and offset voltage
■ Low noise output: 2.1mVrms (max.)
■ Fast response time: 1μs (typ.)
■ Small-sized package, halogen free
