Metal-to-ceramic heating connectors
Metal-to-ceramic heating connectors are crucial to ensure a safe and reliable electrical connection for mineral insulated heating conductors. These ceramic power connectors are constructed to match the same extreme environments as the conductor (high temperatures and vacuums). Depending on the version, currents up to 30A are possible. Kamet’s ceramic power connectors are specifically designed for our top-class range of ARi heating elements.
Product summary
- Suitable for UHV applications
- Can withstand temperatures up to 500°C
- Ensures safe and reliable electrical connection
- Maximum permissible power up to 30A
Using ceramic power connectors
Metal-to-ceramic heating connectors can withstand extreme environments such as high temperatures and vacuums (depending on the design, up to 500°C max). These accessories are designed specifically for our range of ARi mineral insulated conductors and, as such, have the same industrial applications. These include (among others) the following industries :
Our metal-to-ceramic heating connectors are a popular choice for vacuum applications. This is because of the reliable and safe design of the connectors, ensuring an excellent connection between the power cable (usually not in a vacuum) and the heating element (often in a vacuum).
Specifications and physical properties
The following tables provide a full overview of the specifications and parameters for our range of ceramic power connectors. A few notes in addition to these data tables:
- Cold-ended heaters can be used to lower the temperature at the connector, where necessary.
- The connectors are suitable for ultrahigh vacuum (UHV) applications up to 10-9 bar.
- Connection to the power cable can be made in different ways depending on the setup (crimping, screwing, soldering etc.)
- To ensure longevity care must always be taken to protect the ceramic construction parts from excessive mechanical stress, impact and/or shock.
