Our J-type thermocouple extension wire with FEP (Fluorinated Ethylene Propylene) insulation is engineered for precise temperature signal transmission in demanding industrial environments. The FEP insulation provides superior electrical insulation, high-temperature tolerance, and chemical resistance, making it ideal for applications in chemical plants, power generation facilities, and food processing industries.

• Accurate Signal Transmission: Maintains precise thermoelectric signal transfer from J-type thermocouples to measurement devices
• High-Temperature Resistance: FEP insulation withstands continuous operation up to 200°C with higher short-term peaks
• Chemical Resistance: Excellent protection against acids, alkalis, and solvents in corrosive environments
• Reliable Insulation: Superior electrical insulation minimizes interference for stable signal transmission
• Flexible Design: Easy installation in tight spaces with complex routing requirements
• Durable Construction: Resistant to aging, UV radiation, and mechanical abrasion for long service life

• Positive Conductor: Primarily iron with trace elements for optimal electrical properties
• Negative Conductor: Constantan alloy (60% copper, 40% nickel)
• FEP Insulation: Fluoropolymer structure for exceptional chemical and thermal resistance

• Spool-wound packaging (plastic or cardboard)
• Optional pre-crimped terminals (bullet, spade, or bare-ended)
• OEM support including custom printing and labeling
