Overview

The IS16K vacuum interlock switch is designed to safeguard the operator by ensuring that electrical circuits in the vacuum chamber do not remain energized when the system is let up to atmosphere.

Typical applications include interlocking of the HT cleaning or process circuits on thin film deposition and vacuum systems.

The IS16K is high vacuum compatible and corrosion resistant, with all wetted parts made from stainless steel. A high current rating allows direct switching of loads without additional relays or external power supplies.

Technology

The Edwards IS16K Vacuum Interlock Switch is designed for applications where the electrical circuits within the vacuum chamber must be de-energised when the vacuum system is let up to atmosphere.

Typical applications include interlocking of the HT cleaning or process circuits on thin film deposition and vacuum systems. The interlocking switch consists of a positive break microswitch operated by a snap action diaphragm to ensure rapid separation of the microswitch contacts.

The diaphragm is enclosed within the vacuum switch housing which is surrounded by atmospheric pressure and is coupled to the vacuum system by a NW16 flange. The absolute switch point pressure will therefore vary by the same amount as the atmospheric pressure.

The set-point is non-adjustable and cannot be tampered with.

Applications

  • Furnaces
  • Laboratories
  • Tank units
  • Packaging
  • General purpose pumping units
