Frequently Asked Questions

What is a vacuum relay?

A vacuum relay uses contacts sealed in a vacuum to prevent arcing and oxidation, making it ideal for high voltage and high frequency switching applications.

What's the difference between vacuum and gas-filled relays?

Vacuum relays use a vacuum to insulate contacts, while gas-filled relays use pressurized gas (like SF6) for higher dielectric strength and current interruption.

Can you customize relays?

Yes, we offer OEM/ODM services. Our engineering team can develop relays with specific voltage, current, coil, and form factor requirements.

What applications are your relays used in?

Our relays are used in RF antenna tuning, industrial heating, medical equipment, radar systems, pulse forming networks, and high-voltage test instrumentation.
