NVE AD021-00E

NVE AD021-00E
The NVE AD021-00E 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
  • Precision digital magnetic sensor
  • Digital NPN open-collector output
  • Supply voltage 4.5Vcc to 30Vcc
  • Supply current 2.5mA (Vcc=12V)
  • Output drive 20mA
  • Temperature and voltage stability
  • MSOP8 package
  • Frequency response to 100KHz

The AD021 sensor outputs turn ON when the magnetic field exceeds the 20Oe operate point, and OFF when the field drops below 10Oe. The output is “Omnipolar”, meaning the output will turn ON irrespective of the magnetic field polarity. The AD021 outputs are NPN open-collector and should have external pull-up resistors. For microcontroller interfaces, the microcontroller’s input pull-up resistors can be activated.

Typical applications for the AD series include:

  • Motion, speed and position sensing
  • Pneumatic cylinder position sensing
  • Speed sensing
