HIA-C04 series current sensors are measurement modules that convert the measured current into a proportional output of current or voltage using the Hall closed-loop (magnetic balance) principle. They have the characteristics of high accuracy, high linearity, high integration, small size, simple structure, long-term stability, and adaptability to various working environments.
The HIA-C04 series current sensor uses a magnetic balance principle to provide precise current measurement with high resolution and integrated design. It is suitable for applications such as power, oil, petrochemical, railway, communications, and building automation, and can measure AC, DC, and mixed currents.
The device features a rated current of 25 mA, a conversion ratio of 1000:1, and operates from –25 °C to +70 °C (storage –40 °C to +85 °C). It includes a compact PCB‑mountable package, low power consumption (≈10 mA), and protection against ESD and overload. This manual is written in Japanese.
