The Pololu CT433-HSWF70MR TMR Current Sensor Compact Carrier -70A to +70A, 3.3V is a sophisticated current sensor designed for high dV/dt applications, offering a 1 MHz bandwidth with low noise. Utilizing Allegro’s XtremeSense™ TMR technology, it provides high accuracy and electrically isolated current measurements. The sensor is suitable for both AC and DC currents, with a response time of 300 ns and an analog output that is independent of supply voltage variations. It is designed for nominal 3 V operation and can handle bidirectional input currents from -70 A to +70 A.
The compact carrier board is engineered to minimize power loss and is compatible with standard solderless breadboards. It features a non-ratiometric output, ensuring consistent sensitivity and zero point regardless of supply voltage fluctuations. The sensor includes an optional overcurrent fault output for enhanced safety in high-current applications.
Note: Exceeding temperature or current limits can cause permanent damage to the sensor. Handle with care to avoid burns.
