Product Overview
The Allegro XtremeSense CT426 is a high-bandwidth, ultra-low noise integrated contact current sensor designed for high-accuracy current measurements. Leveraging Allegro's patented XtremeSense TMR technology, this sensor enables precise current sensing across various industrial, consumer, and automotive applications. It supports eight current ranges, with an integrated current-carrying conductor (CCC) capable of handling up to 65 A. The device provides a linear analog output voltage and achieves a total output error of less than 1.0% full-scale (FS). With a fast response time of approximately 300 ns and immunity to common mode fields, the CT426 is an ideal solution for applications requiring reliable and accurate current monitoring.
