Key Specifications

This header connector boasts several critical specifications that define its functionality and suitability for various applications:

Type: Header – This attribute clearly identifies the component as a header, which is a male connector designed to be mounted on a PCB. Headers typically consist of a row or rows of pins that mate with a corresponding female receptacle, facilitating modular connections within an electronic system.

Pitch: 1.27mm(.050in) – The pitch refers to the center-to-center distance between adjacent pins. A 1.27mm pitch is considered a fine pitch, enabling higher density connections in a smaller footprint. This is crucial for miniaturized electronic devices where board space is at a premium, allowing for more compact designs without sacrificing connectivity.

Series: A1276HWV – This indicates the product series to which the header belongs. Components within the same series often share common design characteristics, ensuring compatibility and consistency across a range of related products. Understanding the series helps in identifying compatible mating parts and understanding the overall product family’s capabilities.

Contact Finish: Gold (Au) Plating – Gold plating on the contacts is a premium feature, offering excellent electrical conductivity and superior corrosion resistance. Gold is highly resistant to oxidation and tarnishing, ensuring reliable long-term electrical connections, especially in harsh environments or applications requiring high signal integrity and frequent mating cycles. This significantly enhances the connector’s lifespan and performance.

Number of Rows: 1 – This header features a single row of pins. Single-row headers are commonly used for linear connections or where space constraints dictate a narrow profile. They are straightforward to integrate into PCB layouts and are suitable for applications requiring a specific number of discrete connections.

Contact Material: Brass – Brass is a widely used material for electrical contacts due to its good conductivity, excellent machinability, and mechanical strength. It provides a solid foundation for the gold plating, ensuring the contacts maintain their shape and electrical properties over time, contributing to the overall reliability of the connector.

Connector / Cable Type: Header – This reiterates that the component is a header, emphasizing its role as a board-mounted male connector. This distinction helps in selecting the correct mating components and understanding its function within an interconnect system.

Housing / Plastic Material: Nylon 6T UL94V-0 – The housing material, Nylon 6T, is a high-performance thermoplastic known for its excellent mechanical strength, rigidity, and heat resistance. The UL94V-0 rating signifies that the material meets the highest flammability standard, meaning it self-extinguishes within 10 seconds on a vertical burn test and does not drip flaming particles. This is a critical safety feature, especially in applications where fire resistance is a concern.

Number of Positions / Conductors: 29 – This specifies that the header has 29 individual pins or positions for electrical connections. The number of positions is a key factor in determining how many signals or power lines can be routed through the connector, making it suitable for applications requiring a precise count of interconnections.

Features and Benefits

• High-Density Connectivity: The 1.27mm pitch allows for a compact design, enabling more connections in a smaller area, which is ideal for miniaturized electronic devices and space-constrained applications.
• Superior Signal Integrity: Gold (Au) plating on the brass contacts ensures excellent electrical conductivity and resistance to corrosion, guaranteeing stable and reliable signal transmission over the product’s lifespan.
• Enhanced Safety and Durability: The Nylon 6T UL94V-0 housing provides robust mechanical protection and superior flame retardancy, contributing to the overall safety and longevity of the electronic assembly.
• Versatile Application Range: With 29 positions and a single-row configuration, this header offers flexibility for various data, power, and signal interconnections across diverse electronic systems.
• Reliable Manufacturer: Produced by CJT, a recognized leader in connector solutions, ensuring consistent quality, performance, and adherence to industry standards.
