Technical Overview
Multipin feedthroughs carry multiple signal, power and data lines through a single vacuum port, with pins sealed into a ceramic or glass insulator. MIL-Spec MS, USB and SUB-D styles keep contact integrity while preserving UHV hermeticity.
Typical Applications
- Mass spectrometers and surface-analysis instruments
- Vacuum gauges and process instrumentation
- Semiconductor process chambers
- Thin-film deposition and coating systems
