A1276HWV-S-2x10P-H20-E50-9T A1276HWV-S-2x10P-H20-E50-9T Header

A1276HWV-S-2x10P-H20-E50-9T is a high-quality header connector manufactured by CJT, a reputable name in the electronics industry. This specific component falls under the Connectors & Cables category, designed to provide reliable electrical connections in a wide array of electronic assemblies. Headers, also known as pin headers, are essential interface components that facilitate the connection between printed circuit boards (PCBs) and other electronic modules or cables. This particular header is engineered for precision and durability, featuring a compact 1.27mm pitch, making it suitable for space-constrained applications where robust and consistent signal transmission is paramount. CJT’s commitment to quality ensures that this header meets stringent performance requirements for various professional and industrial uses.

Key Specifications

This CJT header boasts several critical specifications that define its performance and suitability for different applications:

Type: Header – This classification clearly identifies the component as a male connector, typically featuring pins that mate with a female receptacle (wafer) to establish an electrical connection. Headers are fundamental for modular design in electronics.

Pitch: 1.27mm(.050in) – The pitch refers to the center-to-center distance between adjacent pins. A 1.27mm (0.050 inch) pitch is considered fine-pitch, allowing for higher pin density in a smaller footprint. This is crucial for miniaturized electronic devices where board space is at a premium, enabling more connections within a limited area.

Series: A1276HWV – Identifying the series helps in cross-referencing and ensuring compatibility within CJT’s product line. Components within the same series often share common design characteristics and mating profiles, simplifying design and procurement processes.

Contact Finish: Gold (Au) Plating – Gold plating on the contacts is a premium feature that significantly enhances conductivity and corrosion resistance. Gold is an excellent conductor and is highly resistant to oxidation and tarnishing, ensuring stable, low-resistance connections over extended periods, even in harsh environments. This contributes to the long-term reliability of the connection.

Number of Rows: 1 – This header features a single row of pins. Single-row headers are often used for simpler connections, power distribution, or when space constraints dictate a linear arrangement of contacts. They are straightforward to integrate into PCB designs.

Contact Material: Brass – Brass is a widely used material for electrical contacts due to its good electrical conductivity, excellent machinability, and mechanical strength. It provides a solid foundation for the gold plating, ensuring the contacts can withstand repeated mating cycles without deformation while maintaining electrical integrity.

Connector / Cable Type: Header – This attribute reiterates the component’s primary function as a header, emphasizing its role as a board-to-board or board-to-wire interface. It helps in categorizing and selecting the correct mating components.

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 indicates that the material is self-extinguishing within 10 seconds on a vertical burn test, signifying a high level of flame retardancy. This is a critical safety feature for electronic components, especially in applications where fire safety standards are paramount.

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 PCBs.
• Superior Electrical Performance: Gold (Au) plating on brass contacts ensures excellent conductivity, low contact resistance, and exceptional resistance to corrosion and oxidation, leading to reliable and stable electrical connections over time.
• Enhanced Durability and Safety: The robust Nylon 6T housing provides mechanical strength and rigidity, while its UL94V-0 flame retardancy rating offers critical safety benefits, preventing the spread of fire in electronic assemblies.
• Versatile Application Range: Designed for a wide array of uses, this header is suitable for various industrial, commercial, and consumer electronics applications requiring reliable board-to-board or wire-to-board interfaces.
• Trusted Manufacturer Quality: Produced by CJT, a recognized manufacturer in the connector industry, ensuring adherence to high manufacturing standards and consistent product quality.

Typical Applications

The A1276HWV-S-2x10P-H20-E50-9T header’s specifications make it suitable for a diverse range of applications:

• Industrial Control Systems: Used in PLCs (Programmable Logic Controllers), sensor interfaces, and control modules where reliable, high-density connections are needed for data acquisition and process control. The gold plating ensures long-term stability in potentially harsh industrial environments.
• Consumer Electronics: Integrated into compact devices such as smart home appliances, portable gadgets, and multimedia players where space is limited, and reliable internal board-to-board connections are essential for functionality.
• Telecommunications Equipment: Employed in networking devices, routers, and communication modules for internal board connections, ensuring robust signal integrity for high-speed data transmission.
• Medical Devices: Suitable for non-critical medical diagnostic equipment and monitoring systems where compact, reliable, and safe (UL94V-0) interconnections are required for various internal modules.
• Automotive Electronics (Non-Critical): Can be found in infotainment systems, dashboard displays, and auxiliary control units where stable electrical connections are necessary for various electronic sub-systems within the vehicle cabin.
