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 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 a ground surface for a drill hole with H7 tolerance zone which is standard only for high-density cartridge heaters.
