With sensitivity exceeding 200 mV/V/Oe, TMR29xx and TMR27xx series in-plane Tunneling Magnetoresistance (TMR) linear magnetic field sensors suit high-precision or battery-powered, high-end industrial applications. These include weak magnetic field measurement, current sensing, metal object detection, and non-destructive testing. Design options are available for each series; TMR29xx, with ultra-low power in microamperes, and TMR27xx, with customizable sensitivity, noise, and power.
