Multi-Pin Signal Vacuum Feedthrough

This multi-pin vacuum feedthrough represents a typical high-density signal interface designed for control, monitoring, and data acquisition (DAQ) in HV/UHV vacuum systems.

It provides hermetic electrical isolation between atmosphere and vacuum while supporting mixed signal types, stable grounding, and low-noise transmission for research, accelerator, and laboratory instrumentation.

• Pin count: reference configuration
• Vacuum rating: HV / UHV compatible
• Flange: CF, KF, or custom bolt pattern
• Signal types: DC, low-level analog, differential (e.g. RS-485)
• Sealing: Ceramic-to-metal hermetic sealing
• Bakeout: Supported (temperature depends on design)

What This Product Demonstrates

FAQ

Is this a standard off-the-shelf product?
No. This page shows a reference configuration. Each multi-pin feedthrough is custom-designed based on system requirements.

Can the pin count be changed?
Yes. Pin count, spacing, and layout can be customized to match voltage, signal integrity, and mechanical constraints.

Is this suitable for UHV bakeout?
Yes. Designs can support UHV and bakeout depending on material selection and geometry.
