A1276HWV-S-2P-B-E34-T A1276HWV-S-2P-B-E34-T Header

A1276HWV-S-2P-B-E34-T is a high-quality header component manufactured by CJT, a reputable name in the electronics industry known for its reliable connector solutions. This specific part falls under the Connectors & Cables category, more precisely Headers / Wafers, and is designed to provide robust and precise electrical connections in a variety of electronic assemblies. Headers, also known as pin headers, are a type of electrical connector that consists of one or more rows of pins. They are commonly used to connect two printed circuit boards (PCBs) or to provide a connection point for external cables and components. The A1276HWV-S-2P-B-E34-T is engineered for applications requiring a compact footprint and dependable signal integrity, making it an essential building block for modern electronic designs.

Key Specifications

This header boasts several critical specifications that define its performance and suitability for various applications. The ‘Type’ attribute confirms it is a Header, indicating its fundamental function as a board-to-board or board-to-wire interface. The ‘Pitch’ of 1.27mm (.050in) is a crucial dimension, representing the center-to-center spacing between adjacent pins. This fine pitch allows for high-density interconnections, which is vital in miniaturized electronic devices where space is at a premium. The ‘Series’ A1276HWV identifies it as part of CJT’s A1276HWV product family, ensuring compatibility and consistent performance within that range. ‘Contact Finish’ is Gold (Au) Plating, a premium finish known for its excellent conductivity, corrosion resistance, and durability, which ensures reliable electrical contact over extended periods and numerous mating cycles. With ‘Number of Rows’ being 1, it signifies a single-row header, simplifying board layout and assembly in many designs. The ‘Contact Material’ is Brass, a widely used alloy in connectors due to its good electrical conductivity and mechanical strength. The ‘Connector / Cable Type’ reiterates its function as a Header, emphasizing its role in establishing connections. The ‘Housing / Plastic Material’ is Nylon 6T UL94V-0, a high-performance thermoplastic known for its excellent mechanical properties, high temperature resistance, and a UL94V-0 flammability rating, indicating it is self-extinguishing and contributes to product safety. Finally, the ‘Number of Positions / Conductors’ is 2, meaning this header provides two individual connection points, suitable for specific signal or power requirements.

Features and Benefits

• High-Density Interconnection: The 1.27mm pitch allows for compact designs, enabling engineers to create smaller and more efficient electronic devices without compromising connectivity.
• Superior Contact Reliability: Gold (Au) plating on the contacts ensures low contact resistance, excellent signal integrity, and robust corrosion resistance, leading to a longer operational lifespan and fewer connection failures.
• Durable Construction: Manufactured with a Brass contact material and a Nylon 6T UL94V-0 housing, this header offers high mechanical strength and resistance to environmental stressors, ensuring reliable performance in demanding conditions.
• Enhanced Safety: The UL94V-0 flammability rating of the housing material provides an added layer of safety, preventing the spread of fire in case of an electrical fault.
• Versatile Application: Suitable for a wide range of electronic applications, from consumer electronics to industrial control systems, due to its standard form factor and robust specifications.

Typical Applications

This A1276HWV-S-2P-B-E34-T header finds extensive use across various electronic sectors due to its compact size and reliable performance:

• Consumer Electronics: In devices like smartphones, tablets, and wearable technology, where space is extremely limited, this header can be used for internal board-to-board connections, linking modules like cameras, displays, or battery management systems. Its fine pitch is crucial for miniaturization.
• Industrial Control Systems: For connecting sensors, actuators, or communication modules to main control boards in PLCs (Programmable Logic Controllers), motor drives, or HMI (Human-Machine Interface) panels. The robust construction and gold plating ensure reliability in harsh industrial environments.
• Medical Devices: In portable diagnostic equipment, patient monitoring systems, or laboratory instruments, where precise and reliable signal transmission is paramount. The high-quality contact finish minimizes signal loss and ensures accurate data acquisition.
• Telecommunications Equipment: Within routers, switches, and other networking hardware, for connecting various daughter cards or expansion modules to the main backplane. The compact design helps in achieving higher port densities.
• Automotive Electronics: In infotainment systems, engine control units (ECUs), or advanced driver-assistance systems (ADAS), for internal module interconnections. Its durability and resistance to vibrations are beneficial in automotive applications.

In summary, the A1276HWV-S-2P-B-E34-T from CJT is a high-performance, single-row header designed for reliable electrical connections in space-constrained applications. Its premium features, including gold plating and a durable housing, ensure long-term stability and excellent signal integrity.
