High Current Automotive Connectors

QA2506: 2.50mm Pitch High Current Automotive Connectors

QA2506AWR Series (TE-SUBM 025 3P)

The QA2506 series focuses on "precise pitch + efficient assembly + reliable locking". The standardized 2.5 mm pitch balances current carrying capacity and space utilization, making it suitable for high-density circuit layouts.

• Board-Side Connector: SMT soldering design compatible with automated production lines, improving assembly efficiency and soldering stability.

• Housing: Integrates a secondary locking mechanism, providing double protection against detachment through "one-time positioning + secondary reinforcement". Visual locking indicators and an anti-misoperation design further enhance terminal retention force.

• Terminals: Made of phosphor bronze with a nickel-plated tin finish, ensuring excellent conductivity and wear resistance.

• Material: Housing is made of UL94 V-0 flame-retardant plastic, providing superior weather resistance, safety, and electrical performance.

Applicable Standards

Automotive industry standards, USCAR2.0, QC/T1067-2017, and other automotive standards.

Application Scenarios

The QA2506 series 2.5 mm pitch wire-to-board connector is ideal for low- to medium-power automotive electronic applications, combining precise pitch, efficient SMT soldering, secondary anti-detachment locking, and excellent environmental resistance. It is widely used in core automotive modules, including vehicle auxiliary electronics, lighting systems, smart cockpits, and body control modules.

• Automotive Lighting Systems: Suitable for power and signal circuits in modules such as daytime running lights. The UL94 V-0 housing withstands high temperatures, and the secondary locking mechanism resists vibration and impact. The 2.5 mm pitch ensures stable current carrying and prevents lighting failures.

• Smart Cockpit Modules: Board-side SMT soldering supports high-density layouts and automated reflow soldering. Terminal material ensures low-loss signal transmission, preventing issues such as audio noise or touch screen malfunctions.

• Body Control Modules: Used in applications such as power window systems. The combination of secondary locking and SMT interface effectively resists wire pulling and vibration, ensuring stable operation of the vehicle's electronic systems.

The production process employs parallel branches of copper strip stamping–electroplating and injection molding, followed by:

• Pin assembly
• CCD visual inspection
• Tape and reel packaging
• Final inspection
• Warehousing

This ensures consistent quality and reliability throughout the manufacturing process.

• Packaging: Industrial-grade custom corrugated boxes with cushioning pads, reinforced with strapping tape, secured on standard pallets, and wrapped in waterproof stretch film.
• Storage: Retain original packaging; store in a clean, dry, temperature- and humidity-controlled warehouse, away from hazardous materials.
• Transportation: Road transport, international express, air freight, or sea freight. During handling, prevent contact with sharp objects or heavy impacts. Protective equipment should be worn during loading/unloading, and packaging materials should be recycled.

A three-pronged quality control model is established: system certification + full-process control + full life-cycle traceability. Certified by IATF16949 and ISO9001, the process ensures:

• Full inspection of incoming materials
• Continuous monitoring during production
• Comprehensive testing of finished products

This guarantees product consistency, reliability, and high quality.
