⚫ Type J Teflon TC Grade Wire
This Type J thermocouple-grade wire uses 36 AWG solid Iron (+) and Constantan (-) conductors with Teflon insulation for temperature measurement and thermocouple fabrication.
The Teflon jacket is rated for temperatures up to 400°F (204°C). The white Iron (+) conductor is magnetic, providing an additional method for identifying proper Type J polarity. For this 36 AWG configuration, the recommended maximum signal distance is approximately 7 ft without amplification.

Compliance & Risk Mitigation
⚫ Maintains Type J alloy compatibility
🧵 TC-grade wire supports direct measurement
🔴 Correct polarity helps prevent reading errors
🧲 Magnetic Iron aids conductor identification
🔥 Teflon supports temperatures to 400°F
↔️ Observe recommended signal distance
💧 Protect Iron conductor from moisture
Use this thermocouple-grade wire only with compatible Type J circuits and instrumentation. Verify polarity, insulation temperature limits, environmental conditions, wire gauge, and required signal distance before installation. The Iron (+) conductor should be protected from moisture where practical to reduce oxidation and corrosion. Where documented measurement validation is required, annual calibration of the complete temperature measurement system is recommended to confirm continued accuracy and proper operation.
