Pololu CT433-HSWF50DR TMR Current Sensor Large Carrier 0A to 50A, 3.3V
Offers 1 MHz bandwidth for high-speed applications
Features low 1 mΩ current path resistance
Provides 40 mV/A sensitivity with 0.65 V zero point
Operates from -40°C to 125°C
Ideal for high dV/dt and electrically isolated applications
The Pololu CT433-HSWF50DR TMR Current Sensor Large Carrier 0A to 50A, 3.3V is a high-precision, electrically isolated current sensor designed for high dV/dt applications. Utilizing Allegro’s XtremeSense™ TMR technology, it offers a 1 MHz bandwidth with low noise and a typical response time of 300 ns. The sensor provides an analog output voltage proportional to AC or DC currents, with a zero point at 0.65 V and a sensitivity of 40 mV per amp. It is optimized for unidirectional input currents from 0 A to 50 A and operates within a temperature range of -40°C to 125°C.
The sensor's design minimizes power loss with a 1 mΩ primary current path resistance and a 6-layer PCB construction. It features an optional overcurrent fault output and is not ratiometric, ensuring immunity from noisy supplies. The sensor can be integrated into various applications requiring electrical isolation and is compatible with standard solderless breadboards.
Note: This product is intended for use below 30 V. Exceeding temperature or current limits can cause permanent damage to the sensor. Handle with care to avoid burns.
