The vacuum relay makes the relay less prone to arcing. Under ideal conditions, the vacuum is likely to reach a dielectric strength of 10000V per 0.1 mm. In addition, since there is no air, the contacts in the vacuum are not oxidized, so the contact resistance of the vacuum type relay is small and stable. Particularly suitable for use in RF applications. A typical ceramic vacuum relay consists of four basic parts: a sealed arc extinguishing chamber with a contact point inside the arc extinguishing chamber for high pressure resistance. An armature mechanism that moves the movable contact. Powered coil section. An additional part that is easy for the user to install and connect.


Typical application for Relays:

vacuum relays play a vital role when high power and low RF losses are required.
