High Temperature PA9T 2.0MM Pitch Dual Row Female Header Connector Gold Flash

CNJWY presents its advanced High Temperature PA9T 2.0MM Pitch Dual Row Female Header Connector, engineered specifically for applications where thermal endurance and long-term reliability under elevated temperatures are non-negotiable requirements. The connector employs PA9T thermoplastic insulator material reinforced with 30% glass fiber, delivering a continuous operating temperature range extending from -55°C to +125°C with a UL94V-0 flammability classification. This enhanced thermal performance makes the connector ideally suited for under-hood automotive electronics, industrial furnace controls, downhole drilling instrumentation, and power conversion equipment where ambient temperatures routinely exceed standard connector ratings. The 2.0mm pitch provides an optimal balance between compact footprint and robust contact geometry, accommodating higher current ratings of 1.5 AMP per contact while maintaining reliable signal integrity across the complete operating temperature range. With dual row configurations spanning 04P to 60P, this connector delivers exceptional versatility for high-temperature interconnect applications.

• Extended Temperature Operation: The PA9T high-performance polyamide thermoplastic maintains dimensional stability and dielectric strength across a -55°C to +125°C temperature range, significantly exceeding the typical -40°C to +105°C operating window of standard PA6T connectors. This enables deployment in engine compartments, industrial ovens, and outdoor equipment exposed to extreme thermal cycling.
• enhanced PA9T Insulator Technology: PA9T resin provides lower moisture absorption and higher heat deflection temperature compared to PA6T and LCP alternatives. Combined with 30% glass fiber reinforcement, the insulator exhibits minimal thermal expansion and exceptional creep resistance under sustained mechanical load at elevated temperatures.
• Higher Current Capacity: The 2.0mm pitch design utilizing robust phosphor bronze contacts enables a 1.5 AMP per-pin current rating, a 50% improvement over standard 2.54mm pitch dual row connectors, supporting power distribution and higher-current signal applications without thermal derating concerns.
• Gold Flash Reliability System: The gold flash over nickel plating system maintains stable contact resistance below 15mΩ throughout the entire operating temperature range, preventing oxidation-induced resistance increases that can cause signal degradation or thermal runaway in high-temperature environments.
• Comprehensive Certification: Fully compliant with UL, SGS, ROHS, and REACH regulatory standards, with additional support for automotive AEC-Q200 qualification testing upon request. Each production batch includes thermal cycling validation to ensure consistent performance across the rated temperature range.
• Versatile Dual Row Format: The dual row configuration maximizes interconnect density while maintaining sufficient creepage and clearance distances for 500V AC/DC withstand voltage rating, making the connector suitable for both low-voltage signal and moderate-voltage power applications in high-temperature environments.

The PA9T high-temperature 2.0mm female header connector is purpose-designed for thermally demanding applications. Automotive under-hood electronics including engine control units (ECUs), transmission controllers, exhaust gas sensors, and turbocharger actuator modules benefit from the extended temperature rating. Industrial process control equipment such as furnace temperature controllers, chemical process monitors, and foundry automation systems employ these connectors where ambient temperatures routinely exceed 100°C. Power conversion and distribution systems including server power supplies, telecom rectifiers, and solar inverter MPPT controllers leverage the enhanced current rating for reliable power delivery in hot equipment enclosures. Downhole drilling and well-logging instrumentation operating in geothermal environments depends on the PA9T connector's thermal stability. Additional applications include avionics engine monitoring, defense-grade power management, railway traction control, and high-intensity LED lighting thermal management systems.

CNJWY high-temperature PA9T female header connectors are packaged in anti-static protective tubes, with each tube containing 10-40 connectors depending on pin count configuration. All packaging materials are rated for extended storage in environments up to 40°C without degradation, and moisture-barrier packaging with desiccant is available for customers requiring extended shelf life in humid climates. Every production lot undergoes 100% automated optical inspection, contact resistance measurement, and thermal cycling validation from -55°C to +125°C. CNJWY manufacturing operates under ISO9001:2015 certified quality systems with full UL, SGS, ROHS, and REACH compliance. Custom configurations including selective heavy gold plating (15μin or 30μin), insulator color options (black, natural, red), and application-specific pin lengths are available through our OEM engineering team. Standard delivery time is 7-10 working days with minimum order quantity of 2,000 pieces.
