Frequently Asked Questions
Looking for a high-density multipin vacuum feedthrough supplier? How do your CF and KF flanges prevent leakage under UHV?
In ultra-high vacuum (UHV) chambers, dense electrical pin arrays risk dielectric puncture and microscopic vacuum leaks under thermal stress. INNOVACERA supplies CF35, KF25, and KF40 multipin vacuum feedthroughs helium leak-tested to <1×10⁻⁹ Pa·m³/s. Brazed with high-purity alumina ceramics and SUS304 bodies, they reliably isolate up to 1500V and 5A per pin across temperatures from -100°C to +200°C and differential pressures up to 5 MPa.
Need custom pin layouts for vacuum instrumentation? What flange styles and conductor pin counts can you offer?
INNOVACERA manufactures custom multipin vacuum feedthroughs tailored to your exact vacuum chamber wiring and footprint requirements. Beyond our standard 16, 19, and 41-pin setups, we customize pin diameters, conductor materials (OFHC copper, nickel, or stainless steel), and flange standards (CF, KF, ISO, or weldable adaptors) to support your specific voltage, amperage, and space constraints.
