PENNYBOTTOM CARTRIDGE HEATERS SPECIFICATIONS

ELECTRICAL TERMINATIONS

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.

SENSOR OPTIONS

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.

POWER VARIATIONS

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.
