Electrical Terminations

Teflon or silicone lead wires

These leads are either sandwiched between the silicone layers or exit on top of the heater. A small patch is placed on the point of exit to provide extra protection. This causes the formation of a slight bump at the point where the wires are attached. To eliminate this problem, the attachment between the internal resistance wire and the lead wire could be made at an external no-heat  tab.

SJO power cables

When silicone rubber heaters are used independently in an industrial application, they can be made with power cables that exit from a silicone transition box attached to the heater. Proper electrical plugs are available with the power cables.

Thermocouples and thermostats

Silicone rubber heaters can accommodate pre-set or adjustable thermostats, thermal cut-offs, thermal fuses, external “J” type thermocouples and RTDs. Each has a specific temperature range and maximum amperage capability; the factory should be consulted for their availability.
