Maximize your PCB real estate with our 40x2 (80-Pin) Dual Row Male Pin Headers. These headers provide double the connectivity of standard single-row strips, making them the essential choice for complex microcontroller boards, high-speed data buses, and sophisticated robotic control systems.
This collection offers specialized extended pin lengths of 10mm, 20mm, and 30mm. The 20mm and 30mm variants are particularly valued for board-to-board stacking, allowing you to bridge multiple PCBs while providing enough vertical clearance for tall components like capacitors and heat sinks.
High-Density 80-Pin Layout: The 40x2 configuration supports complex wiring and high-count I/O requirements in a compact footprint.
Standard 2.54mm Pitch: Industry-standard spacing ensures 100% compatibility with IDC ribbon cables, female headers, and breadboards.
Precision Snap-to-Size: The dual-row plastic insulator is designed to be easily cut or snapped down to smaller configurations (e.g., 2x10, 2x20).
Robust Copper Alloy Pins: Features high-quality plated pins that provide excellent electrical conductivity and resistance to bending.
Superior Heat Resistance: Crafted from high-grade thermoplastic that maintains structural integrity during high-temperature soldering.
Type: Dual Row Male Pin Header (2x40).
Total Pins: 80 Pins (2 rows of 40).
Pitch: 2.54mm (0.1").
Available Lengths: 10mm / 20mm / 30mm.
Mounting Type: Through-Hole Vertical.
Insulator Material: Black high-temp polyester.
Advanced Embedded Systems: Connecting Raspberry Pi or Arduino Mega style boards to custom expansion shields.
Industrial PCB Stacking: Creating rigid, high-clearance bridges between parallel power and control boards.
Custom IDC Cables: Serving as the termination point for 40-pin and 80-pin ribbon cable connectors.
Prototyping & Testing: Providing 80 individual test points for logic analyzers or multichannel oscilloscopes.
Can I snap these as easily as single-row headers?
Yes, but because of the double row, we recommend using a side-cutter or a hobby knife for a cleaner break between the pins compared to snapping by hand.
Which length is best for stacking?
The 20mm is standard for most board-to-board stacking. Use the 30mm if you have exceptionally tall components (like large electrolytic capacitors) in between the boards.
Are the pins gold-plated?
These headers typically feature a high-quality tin or flash-gold plating to ensure easy soldering and high corrosion resistance.
