Ceramic to metal Multipin Connector Application:
- Semiconductor processing equipment
- Analytical test and measurement equipment
- Pressure transducers
- Power generation (measurement and control technology)
- Particle accelerators
- Furnaces
- Energy research
All receptacles are made from high-purity, vacuum compatible materials. The insulators are made from high-strength, low-loss alumina ceramics that are metalized using the refractory-metal sintering process. Metals include Kovar®, stainless steel, nickel-iron alloys, cupro-nickel alloys, molybdenum, and Alumel®. The assemblies are brazed together using copper, gold-copper, or silver-copper alloys.

Frequently Asked Questions
Looking for a reliable hermetic multipin connectors manufacturer? How do your feedthroughs guarantee zero leakage in UHV systems?
INNOVACERA manufactures high-vacuum and ultra-high vacuum (UHV) multipin connectors featuring 100% helium mass spectrometer leak testing down to <1×10⁻¹⁰ mbar·l/s. Utilizing high-purity alumina ceramics (94%–99%) brazed with Kovar and stainless steel, our hermetic assemblies maintain flawless seal integrity across temperatures from -250°C cryogenic conditions up to +450°C.
Need custom multipin vacuum feedthroughs for high-power equipment? Can you configure pins for both >12kV voltage and 40A current?
Yes. INNOVACERA specializes in custom ceramic-to-metal multipin connectors configured to your exact voltage and amperage requirements—supporting high voltages >12kV DC and high currents up to 40 Amps per conductor. We customize pin layouts, flange interfaces (CF, KF, ISO, or weldable), and air/vacuum-side plug receptacles to meet the specific demands of particle accelerators and semiconductor systems.
