The 509401 PCB SIL Pin Header is a high-quality 40-way single-row (SIL) connector designed for compact and reliable PCB interconnections. Featuring a 1.27mm pitch, this header is ideal for high-density electronic designs where space optimization and precise signal routing are essential.
With its right-angled PCB termination, the connector allows horizontal cable or board connections, making it especially suitable for applications where vertical space is limited. This design helps create clean, organized layouts in tight enclosures and multi-board assemblies.
The gold-plated pins provide excellent electrical conductivity and enhanced resistance to corrosion and oxidation. This ensures stable signal transmission, reduced contact resistance, and long-term durability, even in demanding environments.
Designed as a single-row SIL (Single In Line) header, the 509401 is widely used in embedded systems, development boards, communication modules, industrial electronics, and custom PCB designs. Its robust construction ensures secure mounting and dependable performance in both prototype and production environments.
