CMS Series Electrical Feedthroughs

The CMS Series are electrical feedthroughs for passing current and applying voltage to vacuum chambers with pressure ranging from atmospheric pressure to ultra-high vacuum.

Features

  • Can be used with pressures ranging from 10-2 Pa to ultra-high vacuum.
  • Several models are available, ranging from types for microcurrents (with BNC connectors), to types for large currents (400 A) and high voltages (12 kV).
  • Outstanding heat resistance and low gas emission, ideal for use with ultra-high vacuum.
  • Ceramic and copal materials have similar thermal expansion coefficients, so seals don't leak during bake-out and other processes with temperature variations.
  • Connected electrodes are fixed in place by screws (except for some models), so wiring remains securely in place.

Applications

  • Passing current/applying voltage to ultra-high vacuum systems
