Ruth's sister 24V 65W Heating Cartridge 15CM Green internal power cable

Heating cartridge for 3D printer hotends

This 24 V 65 W cartridge heater fits Volcanos-style hotend blocks and reaches 240 °C from a 25 °C start in about one minute. The 15 mm rod length suits dragon, mosquito, lizard and similar hotend designs without interfering with mounting positions. It is intended for makers and repair technicians who need a direct replacement heater for high-temperature printing.

Green 15 cm lead with MX3.0 terminal

The flexible green cable measures 15 cm and terminates in an MX3.0 connector that requires an adapter board or a custom extension for most control boards. High-quality metal sheathing on the rod resists oxidation and discolouration, while the supple wire insulation reduces fatigue during repeated hotend movements. No additional mounting hardware is included in the package.

Thermal performance and power draw

At 24 V the cartridge draws 65 W and can heat the block to 240 °C in roughly sixty seconds under the stated test conditions. The short 15 cm lead keeps voltage drop minimal, and the metal shell transfers heat efficiently to the heater block without audible noise. Buyers who need longer cable runs or a different connector style will have to source or build an adapter separately.
