Fully Shrouded Tin (Sn) Through-Hole Solder Sealable PCB Mount Header – Technical Overview The fully shrouded tin (Sn) through-hole solder sealable PCB mount header is a robust and reliable interconnect solution designed for printed circuit board (PCB) applications requiring secure, long-lasting connections in demanding environments. This header features a durable housing with a fully enclosed shroud, providing mechanical protection, polarization, and dust/contaminant resistance. The tin-plated contacts ensure excellent solderability and corrosion resistance, making it suitable for a wide range of industrial, automotive, and consumer electronics applications. Key Features and Benefits 1. Fully Shrouded Design The header incorporates a complete plastic shroud surrounding the contacts, offering enhanced protection against physical damage, misalignment, and environmental factors. The shroud also acts as a guide for mating connectors, ensuring proper orientation and preventing reverse insertion. 2. Tin (Sn)-Plated Contacts The through-hole contacts are plated with tin (Sn), providing superior solderability during PCB assembly. Tin plating offers good electrical conductivity and resistance to oxidation, ensuring reliable signal transmission and long-term performance in moderate environmental conditions. 3. Through-Hole Mounting Designed for through-hole PCB assembly, this header provides strong mechanical retention and reliable solder joints. The through-hole design enhances durability, making it ideal for applications subject to vibration or mechanical stress. 4. Solder Sealable The header supports solder sealing, allowing for additional protection against moisture, dust, and other contaminants. This feature is particularly beneficial in harsh environments where long-term reliability is critical. 5. Multiple Configurations Available in various pin counts (e.g., single-row or dual-row) and pitch options (e.g., 2.54mm, 3.96mm), the header accommodates diverse PCB layout requirements. Customizable options may include different shrouding heights and locking mechanisms for added security. 6. High-Temperature Resistance The housing material is typically made from high-temperature thermoplastics (e.g., PBT, nylon), ensuring stability in reflow soldering processes and resistance to thermal degradation. Applications This header is widely used in: - Industrial control systems - Automotive electronics - Power supplies - Medical devices - Telecommunications equipment - Consumer electronics Conclusion The fully shrouded tin-plated through-hole solder sealable PCB mount header delivers a combination of mechanical robustness, environmental protection, and electrical reliability. Its design ensures secure mating, ease of assembly, and long-term performance, making it a preferred choice for engineers designing high-reliability electronic systems.
