CT100 1D Linear TMR Field Sensors Crocus Technology CT100 1D Linear TMR Field Sensors are based on Crocus Technology's Magnetic Logic Unit™ (MLU™) technology. The highly linear devices with wide dynamic ranges enable the sensors to be used in a variety of applications from contactless current sensing to linear and proximity measurements. The CT100 TMR sensors can measure the current from the induced magnetic field of the current-carrying conductor. The linear sensors provide highly accurate measurements. The Crocus Technology CT100 1D linear TMR Field Sensors come packaged in an industry-standard 6-lead SOT-23 package or a very low profile, small form factor 6-lead DFN package for mobile and wearable applications.
