Magnetic Tunnelling Magnetoresistive (TMR) Switch Sensors
 |
Magnetic TMR Switch Sensors integrate ultra-high sensitivity, picoTesla ultra-low noise, ultra-low power, high-speed operation and outstanding temperature performance into a single device. They are ideal choices for battery-powered sensor applications that require high-precision measurement, stringent performance uniformity and excellent temperature stability. Typical applications include motor & fan control, wireless door access switches, intelligent medical appliances such as smart pills and portable drug delivery devices |
