CH1S01xB Current Sensor Family

The Littelfuse CH1S01xB current sensor family employs open loop Hall effect technology to deliver precise and reliable current sensing solutions. These sensors provide dual-channel, ratiometric output signals proportional to the magnetic flux density generated by internal C-core concentrators. Designed for high accuracy and low thermal drift, the CH1S01xB sensors are ideal for applications requiring non-intrusive current measurement. They operate with a unipolar +5 V_DC power supply and offer an operating temperature range from -40°C to +125°C. The sensors are available in various configurations, including standard and aperture variants, and can measure primary currents up to ±1,100 A. With features such as high sensing accuracy, low thermal offset drift, and robust mechanical characteristics, the CH1S01xB family is well-suited for demanding environments in automotive and industrial applications.
