Why MiRelay High Voltage?

High voltage switching requires precision engineering. Our relays utilize Vacuum Reed Switches with Tungsten or Rhodium contacts to withstand arcing and prevent oxidation.

  • 01. Tungsten Contacts: High melting point enables switching of high voltages without contact welding.
  • 02. Vacuum Sealing: The glass capsule is evacuated to high vacuum ($10^{-8}$ Torr) to boost isolation voltage.
  • 03. Long Creepage Path: Our coil bobbin and package design ensures maximum distance between high voltage pins and the coil.
