High Quality PVC Insulated Type JX Extension Wire 2×1.5mm² Thermocouple Cable
Type JX Thermocouple Extension Wire (2×1.5mm², PVC Insulated)
Type JX thermocouple extension wire (2×1.5mm²) from Tankii Alloy Material is a heavy-duty signal transmission cable engineered to extend Type J (Iron/Constantan) thermocouple circuits from the cold junction to instrumentation. Featuring JX-grade conductors matched to Type J thermoelectric characteristics and durable PVC insulation, this cable delivers stable EMF output up to 105°C continuous / 120°C short-term operation.
Standard Designations & Core Material Foundation
- Thermocouple Type: Type J (Iron/Constantan)
- Wire Type: JX (Extension Grade)
- Conductor Specification: 2×1.5mm² solid/stranded conductors (±0.05mm tolerance)
- Insulation Material: Polyvinyl Chloride (PVC, 105°C rating)
- Color Coding: Red (Positive, Iron) / Black (Negative, Constantan)
- Compliant Standards: IEC 60584-3, GB/T 4989-2013, ASTM E230, RoHS 2.0

Key Product Advantages
Heavy-Duty Mechanical Strength (2×1.5mm²)
- Increased Current Capacity: 1.5mm² cross-section provides higher current-carrying capacity for long-distance runs without signal degradation
- Enhanced Durability: Thicker conductors offer superior tensile strength and vibration resistance in industrial settings
JX Grade Signal Integrity
- Matched EMF Characteristics: Alloys replicate Type J thermoelectric behavior up to 105°C, minimizing measurement errors
- Low Contact Resistance: Larger conductor surface area ensures excellent electrical contact and reduced signal noise
Cost-Effective & Versatile Installation
- PVC Insulation Performance: Resistant to moisture, oil, and abrasion for indoor and protected outdoor use
- Easy Termination: 1.5mm² size compatible with standard industrial terminal blocks and crimp connectors
