Automotive & Industrial Open Loop Current Sensor - Cable Mounting

Piher Sensing Systems’ HCSO-1W family of open loop current sensors generates a ratiometric analog output voltage signal proportional to the current flowing through the conductor. Based on Hall effect technology the sensor has been designed for accurate measurement of AC and DC currents in automotive battery management and motor control applications with higher efficiency and lower energy loss.
