🟡 Type K Extension Grade Wire 20 Ga.
This Type K thermocouple extension-grade wire is designed to extend the connection between a Type K thermocouple and compatible temperature instrumentation. It uses 20 AWG solid Chromel (+) and Alumel (-) conductors with a durable polyvinyl jacket.
The wire is rated for temperatures up to 220°F (105°C). Standard Type K color identification uses a yellow positive Chromel conductor and red negative Alumel conductor. The red Alumel (-) conductor is magnetic, which can also assist with conductor identification.

Compliance & Risk Mitigation
🟡 Maintains Type K circuit compatibility
🧵 Extension grade supports instrument wiring
🔴 Correct polarity helps prevent reading errors
🧲 Magnetic Alumel aids conductor identification
🔥 Observe the 220°F insulation limit
🔌 Correct connections maintain signal integrity
📋 Proper identification simplifies maintenance
Use this extension-grade wire to extend compatible Type K thermocouple circuits to meters, controllers, recorders, and other instrumentation. Verify polarity, insulation temperature limits, environmental conditions, and required wire length before installation. Extension-grade wire should not be substituted for thermocouple-grade wire when fabricating the actual sensing junction. Where measurement validation is required, annual calibration of the complete temperature measurement system is important for confirming continued accuracy and proper operation.

Things to remember when working with “K” Thermocouple Wire. Remember RED is always negative.
Do not mis-match other thermocouple calibrations ( ie: J, T, E, etc...) to thermocouple plugs and jacks. This creates serious thermocouple error. Remember to match the color codes Yellow to Yellow "+" and Red to Red "–"
If connecting wire to miniature thermocouple plugs and jacks it's easier to attach 24 ga or smaller wires and use a cable clamp to prevent shorting of the wires inside the connector.
If using standard size thermocouple plugs and jacks make sure to use a cable clamp to secure the wire to the plug or jack. Additionally this will help stop the wires from twisting and shorting inside the connector. When that happens you have created a new thermocouple junction and this means your instrument will read ambient temperature and not the process temperature.
