Product Overview
This sensor uses a magnetic balance (compensated) Hall effect architecture to maintain stable output across the measurement range. The device supports DC current input from 0 up to ±250 A and outputs a proportional ±40 mA signal. The housing is made from PC/ABS rated UL-94 V0, offering fire resistance and durability.
This sensor is ideally suited for integration with control systems, power measurement units, battery management systems, and instrumentation that accept mA-level input. It is especially useful in retrofit installations where safety, accuracy, and ease of integration are important.
