Large Current Sensor -200A to +200A - 5V Logic

The Pololu 5V Large Current Sensor is an essential component for precise high-current monitoring in electronics. Built on Allegro’s ACS72981ELRATR-200B5, this Hall effect-based sensor is engineered for bidirectional currents ranging from -200A to +200A. It boasts a 250 kHz bandwidth and a swift response time of under 2 µs, ensuring real-time, accurate readings. With an internal resistance of just 0.2 mΩ, the sensor minimizes power dissipation and heat, making it perfect for demanding applications.


Designed for 5V operation, this sensor features electrical isolation, enhancing safety and flexibility in circuit design. Its integrated temperature compensation ensures consistent performance across a wide range of temperatures. Clearly marked connections and current flow directions simplify setup, while the “5V B20” marking aids in quick identification. Ideal for power supplies, motor controls, and battery management, this sensor is a reliable choice for high-performance current monitoring.
