Type F: Internally Connected Flexible Leads
Standard Termination for Low-Density Cartridge Heaters. The fiberglass lead wires are internally connected to the terminal pins. This lead termination provides flexibility, permitting the lead wires to be sharply bent as they exit the heater.

Minimum 3/8″ up to 1″ unheated section at the lead end is required.
Standard lead wire temperature rating for HDC & HDM: 842°F (450°C). Standard lead wire temperature rating for LDC: 482°F (250°C).
Standard 10″ (254 mm) leads. Specify longer leads.
For HDC & HDM heaters, leads longer than 60″ require a splice.

Type TJ1 and TK1: Grounded at Disc End
The thermocouple junction is grounded to the sheath at the disc end and packed with MgO. The concave end disc is filled with silver solder and ground flat. When inserted into a flat end blind hole, it will provide fast responsive temperature readings. Widely used in Hot Runner mold probes.

Type DW: Distributed Wattage
Cartridge heaters can be designed to vary the wattage along the length of the heater. Specify number of zones and the required watts and length per zone starting from the disk end. Leads can be connected externally or internally. Picture shows a heater with Type N externally connected leads. Heaters with other terminations may require a longer cold section at the lead end.
