Reed Sensor Monitors Vehicle Power Windows

Features

  • Contacts dynamically tested
  • Cylindrical hole and screw fastening mounting
  • Magnet and reed sensor are isolated and have no physical contact by typically having the magnet mounted on the window motor and the reed sensors mounted and positioned to accurately detect the motor rotation
  • The reed switch used in the reed sensor is hermetically sealed and is therefore not sensitive to rough, wet environments
  • The permanent magnet is not affected by its environment
  • Tens of millions of reliable operations
  • Surface mount and through hole packages available
