Contactless Current Sensors

High resolution, high accuracy and fast response time for isolated current sensing. TMR sensor technology provide stability over temperature with market leading accuracy.

1 MHz Bandwidth
0.7% FS Accuracy
300 ns Response Time
Immunity to Common Mode Fields
Up to ~4,000 A with bus bar or PCB trace

Common Mode Field Rejection (CMFR) cancels out noise from external fields Removes the need for shielding against stray magnetic fields
