Samtec 40 Pin Male to Male Header 2.54 mm

40-Pin Male-to-Male Header (2×20) — 2.54 mm Pitch

The 40-pin male-to-male header with a 2×20 dual-row layout and 2.54 mm pitch is a dependable connector designed for general PCB interconnections and board-stacking tasks. Its standardized spacing supports integration with Arduino, Raspberry Pi, development boards, and custom electronic assemblies. The connector uses phosphor-bronze contacts with optional gold or tin plating to maintain low contact resistance and stable electrical performance across repeated mating cycles. The insulating body provides mechanical strength and secure alignment during soldering and operation.

Its compatibility with common prototyping equipment and breadboards makes it suitable for educational, industrial, and commercial builds. The header meets essential electrical and environmental requirements, including high insulation resistance, UL94V-0 flammability, and a wide operating-temperature range. Multiple mounting styles—such as straight and right-angle through-hole—allow integration into a variety of PCB layouts. For complete technical specifications, refer to the Samtec TSS series datasheet.

The header is used for board-to-board connections, breakout wiring, and structured routing in electronic systems. Its dimensional accuracy and material stability support long-term use in assemblies where consistent mechanical and electrical performance is required.
