Amphenol Piher HCSO-1W Automotive Hall Effect Current Sensors
Amphenol Piher HCSO-1W Automotive Hall Effect Current Sensors are open-loop current sensors that generate a ratiometric analog output voltage signal proportional to the current flowing through the conductor. Utilizing Hall effect technology, the HCSO-1W delivers reliable performance with excellent linearity and low hysteresis, ensuring precise monitoring of DC and AC currents up to ±1000A. The open-loop design enables galvanic isolation between the primary conductor and the measurement electronics, enhancing safety and system integrity.
Built for harsh environments, the Amphenol Piher HCSO-1W features a robust construction that withstands extreme temperatures, vibrations, and electrical noise, making it ideal for electric vehicles, battery management systems, and power distribution units. These sensors offer fast response times and high bandwidth, supporting dynamic current measurement in demanding applications. With a compact form factor and easy integration, the HCSO-1W simplifies design while meeting stringent automotive standards for reliability and durability.
