CT426 XtremeSense® TMR Sensors Allegro MicroSystems CT426 XtremeSense® TMR Sensors offer a 3V to 3.6V supply voltage range, up to 30A current rating, and 1MHz bandwidth. These are high bandwidth and ultra-low noise integrated contact current sensors that use XtremeSense TMR technology that enables high-accuracy current measurements for various applications. CT426 sensors support four current ranges where the integrated current-carrying conductor (CCC) handles up to 30A of current and generates a current measurement as a linear analog output voltage. Allegro MicroSystems CT426 XtremeSense TMR Sensors are ideal for solar inverters, enterprise electronics, and battery management systems.
