1.AA11R21421285C1 is a DIP 90° combination connector that integrates 2.54mm pitch signal pins (6 sets) and 7.62mm pitch power pins (5 sets). It is specifically designed for PCB board mounting, supporting both signal transmission and power supply.

2.The housing is made of black LCP material and complies with the UL94V-0 flame-retardant standard. 

The contacts are made of C18400 material (gold-plated in contact areas, cold-flash plated in solder areas, with an overall nickel underlayer of ≥50μ"), and the grounding components are brass (matte tin-plated with a thickness of ≥80μ"), ensuring safety and durability.

3.The signal pins have a rated current of 10A and the power pins 55A (both UL-certified). 

The power pins can withstand DC 1000V for 1 minute, with a contact resistance of ≤0.6mΩ and an insulation resistance of ≥5000MΩ (for power pins), enabling efficient and stable transmission.

◆◆ Product Advantage

1.Safe and Durable Materials: The housing is made of UL94V-0 flame-retardant LCP material, reducing fire hazards. The combined design of gold-plated contacts with a nickel underlayer and brass tin-plated grounding components offers both anti-oxidation and anti-corrosion properties. It meets the requirements in salt spray tests, ensuring a long service life.

2.Strong Electrical Performance: The power pins feature a high current-carrying capacity of 55A (UL-certified). The separate layout of signal pins and power pins avoids mutual interference. With high voltage resistance (up to DC 1000V) and high insulation resistance (up to 5000MΩ), it delivers excellent electrical stability and safety. The extremely low contact resistance (only 0.6mΩ max for power pins) enables efficient transmission of signals and electricity with minimal loss.

3.Wide Environmental Adaptability: It has an operating temperature range of -55℃ to +125℃, making it suitable for extreme temperature environments such as outdoor settings and industrial equipment. With salt spray resistance and rust resistance, it is applicable to harsh working conditions like humid and salt-spray-rich environments.

4.Excellent Compatibility with Installation and Processes: The DIP 90° design facilitates vertical mounting on PCB boards. It features precise dimensional tolerance control and strong adaptability to PCB layouts (recommended tolerance of ±0.05mm). It can withstand high-temperature processing at 265℃ and is compatible with mainstream soldering processes, enabling convenient production and assembly.

5.Standardized Specifications: It complies with UL certification standards, with clear model identification and definite order information as well as recommended PCB layouts, facilitating bulk procurement and standardized applications.
