Multi-Pin & Signal Vacuum Feedthroughs (Control, Monitoring, DAQ)

Single-pin to multi-pin hermetic interfaces for control wiring, instrumentation, and differential signaling in HV/UHV vacuum systems.

• Best for: sensor readout, motion control, control systems, multi-channel routing
• Common interfaces: multi-pin, differential pairs (RS-485), mixed-signal layouts
• Customization: pin count, per-pin rating, shielding/grounding, connector preference

Overview

Multi-pin and signal vacuum feedthroughs enable transmission of DC, low-noise, and differential signals across vacuum boundaries. They are used for control, monitoring, and data acquisition in accelerator and laboratory vacuum systems.

What Is a Multi-Pin Signal Feedthrough?

A signal feedthrough integrates single-pin or multi-pin electrical paths through a vacuum flange using hermetic sealing. Designs may support mixed signal types within one assembly.

• DC control signals
• Low-level analog signals
• Differential signaling (e.g., RS-485)
• Mixed-signal configurations

Design Features
