The 2.54mm Box Header SMT is a highly reliable surface-mount technology (SMT) connector designed to mate with 2.54mm IDC flat ribbon cables. Its unique boxed design provides a physical shield for the pins, ensuring a stable and reliable connection while protecting the pins from damage caused by accidental pulling or bending. This header is widely used in electronic devices that require dense, reliable, and detachable wire-to-board connections.
Key Features
- Standard Pitch: The 2.54mm (0.1-inch) standard pin pitch is compatible with most IDC connectors and prototyping boards on the market.
- Surface Mount Design (SMT): Specifically engineered for automated manufacturing, it can be directly soldered onto the PCB surface, which significantly improves assembly efficiency.
- Boxed Structure: The boxed design offers extra mechanical protection, ensuring the security of the cable-to-header connection and preventing pin misalignment or short circuits.
- Polarized Notch: Typically includes a polarizing notch to ensure correct orientation during mating, preventing reverse connections.
- Versatile Pin Counts: Available in a wide range of pin counts, from 6 to 64 pins, to meet diverse design requirements.
- High Reliability: Made from high-quality materials to ensure excellent conductivity and durability.
