Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
The NVE AD621-00E precision digital magnetic sensor from NVE have a precision magnetic operate point of 20Oe (Typ.) with a frequency response of 0 to 100KHz and an excellent temperature and voltage perfomance. NVE’s AD Series of GMR switches are the industry standard for sensitivity and precision. These switches integrate GMR sensor elements with digital signal processing electronics, and are more precise than other magnetic sensors, with magnetic field operate points being stable over voltage and temperature extremes
The AD621 sensor outputs turn ON when the magnetic field exceeds the 20 Oe operate point, and OFF when the field drops below 10 Oe. The output is “Omnipolar”, meaning the output will turn ON irrespective of the magnetic field polarity. Digital switching is achieved when the magnetic field passes across the axis of the IC. The AD621 outputs consist of one NPN open-collector current-sink and one PNP open collector current-source output. These outputs should have external pull-up and pull-down resistors. For microcontroller interfaces, the microcontroller’s input resistors can be activated.
Typical applications for the AD series include:
