Cartridge Heater with Built-in Thermocouple

Cartridge heater with built-in thermocouple combines heating and temperature sensing in one compact heating element. The integrated K-type thermocouple provides temperature feedback close to the heating area without requiring a separate temperature sensor.

This design is suitable for precision molds, heating blocks, laboratory equipment, automation systems, packaging machinery, and other applications requiring integrated heating and temperature monitoring. Standard models use a SUS321 stainless steel sheath, built-in K-type thermocouple, and 220V power supply. J-type thermocouples and custom dimensions, power, and lead configurations are also available.

See our
Cartridge Heater Applications
page for more application information.

Installation & Wiring

• The heating wires and thermocouple wires are separate circuits and must be connected correctly.
• Incorrect wiring may cause heating failure, inaccurate temperature readings, or controller errors.
• An H7 close-fit bore is recommended for stable heat transfer and temperature sensing.
• The heated section should maintain good contact with the bore wall to reduce thermal resistance.

If you are experiencing slow heating, temperature fluctuation, frequent burnout, or other cartridge heater problems, see our
Cartridge Heater Troubleshooting Guide
for common causes and practical solutions.
