Cartridge Heaters - Termination Styles
High temperature (840 deg F) fiberglass insulated wire is connected externally to the two solid pins exiting from the cartridge. A silicone impregnated fiberglass jacket insulates the connection.
To provide flexibility at the lead end, high temperature (840 deg F) leads are connected to the solid pins inside the cartridge.
A bracket having the same diameter as the cartridge provides a 90 degree exit to the fiberglass insulated high temperature wire. The bracket is potted with high temperature cement (480 deg F).
For high temperature applications, screw terminals (#10-32 is standard, other sizes are available) are silver-brazed to the 1” extended solid pins of a cartridge. This type of terminals are not recommended for cartridges having less than ½" diamerter.
Internally connected Teflon leads (480 deg F) with Teflon plugs, protect the cartridge from contamination. High temperature black epoxy or silicone RTV seals are available too. A minimum cold section of 1” at the leads end is necessary to protect the Teflon leads from high temperature.
