  • HOW TO: Cutting & Bending of Reed Switches
    A dry-reed switch can be defined as an assembly that contains two ferromagnetic NiFe contact blades,. hermetically sealed in a glass envelope and filled with an inert gas. Improper handling of the switch and the application of excessive mechanical force during. modification of the switch leads may
  • How to Handle a Reed Switch
    Reed switches consist of two or three metal reed contacts (blades) that are hermetically sealed inside a glass tube. This seal, while strong, may be damaged if proper handling is not used. HSI Sensing has years of experience handling reed switches and have identified several best practices.
  • Operating Principles for Magnetic Sensors
    Magnetic proximity sensors are actuated by the presence of a permanent magnet. Their operating principle is based on the use of reed con-tacts, whose thin plates are hermetically sealed in a glass bulb with inert gas. The presences of a magnetic field makes the thin plates flex and touch each other
  • Handling Switches - Pressure & Pull Forces
    A dry-reed switch can be defined as an assembly that contains two ferromagnetic NiFe contact blades,. hermetically sealed in a glass envelope and filled with an inert gas. The inert gas atmosphere protects the. contact resistance of the reed switch, which is one of its most important electrical
  • Application: Gas Tank Lid Monitoring Sensor (.pdf)
    . Detecting if the lid and gas cap are in place designers have turned to the Reed Sensor which uses hermetically sealed reed switches, and are further packaged in a tough plastic encapsulation.
  • Application: Off Hook Telephone Switching (.pdf)
    the reliability of the electrical on/off connection. MEDER has developed several packages that use hermetically sealed reed switches that completely eliminate this reliability issue.
  • Application: Mobility Equipment & Hospital Beds - Reed Sensor
    . on the contacts. To break through these films. higher switching voltages may be necessary. These higher voltages are not ideal in a hospital bed environment. Now designers have turned to the Reed Sensor which uses hermetically sealed reed switches, which are ideal for switching low signal levels reliably.
