  • Pololu CT432-HSWF70DR TMR Current Sensor Compact Carrier 0A to 70A, 5V
  • Optimized for high dV/dt applications
  • Offers high accuracy with XtremeSense™ TMR
  • Operates at a nominal 5V supply voltage
  • Features non-ratiometric, stable output
  • Ensures electrical isolation in current path

The Pololu CT432-HSWF70DR TMR Current Sensor Compact Carrier 0A to 70A, 5V is a compact, electrically isolated current sensor optimized for high dV/dt applications. It utilizes Allegro’s XtremeSense™ TMR technology to provide high accuracy and bandwidth for current measurements. The sensor is designed for unidirectional input currents ranging from 0 A to 70 A and operates at a nominal 5 V supply voltage.

This sensor features a high-bandwidth 1 MHz analog output and a typical response time of 300 ns. It is suitable for applications requiring electrical isolation and can be inserted anywhere along the current path. The sensor's output is non-ratiometric, ensuring stability against supply voltage variations.

Note: Exceeding temperature or current limits can cause permanent damage to the sensor. Handle with care to avoid burns, and consider additional cooling for continuous currents above 30 A.
