Connection

Leads

	Standard: Fibre glass insulated nickel leads Temperature resistant up to 300 °C
	PTFE insulated nickel leads Temperature resistant up to 260 °C Advantage: moisture tight
	High temperature leads Temperature resistant up to 500 °C Advantage: highly temperature resistant
	Silicone insulated nickel plated copper leads (available only with standard connection type N » see chapter High-Density Cartridge Heaters) Temperature resistant up to 180 °C Advantage: flexible, moisture tight
	Silicone cable (bi-tripolar) Temperature resistant up to 180 °C

Moisture Protection
Instead of sealing the termination with ceramic cement or installing a ceramic cap (» see standard connections in chapter High-Density Cartridge Heaters) we can alternatively produce other kinds of terminations which provide a special moisture protection.

PTFE	Cartridge heaters with a PTFE disk are permanent temperature resistant up to 260 °C and should be used in connection with PTFE insulated leads. Advantage: moisture protected
Silicone	Cartridge heaters sealed with silicone are temperature resistant up to 180 °C and should be used in connection with silicone insulated leads. Advantage: moisture protected
Epoxy	Cartridge heaters sealed with epoxy resin are temperature resistant up to 120 °C (optional 200 °C) and can be used in connection with silicone insulated as well as PTFE insulated leads. Advantage: moisture tight

Earth Lead
Earth leads are available and mountable in fibre glass insulated nickel leads or PTFE (on request).

Differential Power

The cartride heater can usually not emit heat homogenously over its length. For applications in which this is to be avoided, cartridge heaters with heat distribution can be used. For that purpose the heating wire is coiled denser on a specific length (L1 and L2) at both ends. This leads to a relative power increase in these areas (power shares E1 and E2 in %, E1+E2+E3 = 100%).
