HABT Series
Cost efficient insulated current sensor for battery management system +/-100A
HABT Series – Automotive current sensors
The HABT Series expands the HAB Series by integrating both current measurement and temperature monitoring within a single compact device. Designed for high‑power automotive environments, HABT sensors measure DC, AC, and pulsed currents up to ±100 A with full galvanic isolation, and deliver current information to the ECU via a ratiometric voltage output.
In addition, HABT current sensors integrate an NTC thermistor, providing accurate ambient temperature feedback through the same waterproof connector used for current measurement connections.
Based on open‑loop Hall‑effect technology, the HABT Series is optimized for advanced automotive energy management systems that require both current and temperature data for safe and efficient operation.
