Medium-density cartridge heaters produce their energy with a heating coil which is lead through hole ceramics. They are specially suitable for applications where no high surface watt density is needed (max. 15 W/cm² » see formula) or very long cartridge heaters are required.

Standard leads: 250 mm fibre glass insulated nickel lead, externally connected (type N)

If required we can produce the cartridges with an h7 surface which is standard only for high-density cartridge heaters.
