Precision Connectivity: 40-Pin Single Row Round Pin Header (12mm) 🔌🔬

Ensure high-reliability connections in your sensitive electronic projects with our 40-Pin Single Row Round Male Pin Header. Unlike standard square-pin headers, these "turned-pin" style headers feature circular cross-sections, providing a superior fit for IC sockets, high-end connectors, and precision PCB prototyping.

This specific variant features a 12mm total pin length, offering the extra reach needed for specialized mounting or stacking where standard 10mm headers fall short. Whether you are repairing vintage hardware or building modern high-precision modules, these headers provide the mechanical stability and electrical integrity your circuit demands.

Key Performance Features:

• ✅ High-Precision Round Pins: Designed for a smoother interface with female headers and IC sockets, reducing wear and improving contact surface area.

• ✅ 12mm Extended Length: Perfect for custom clearance requirements or through-hole applications requiring a longer contact point.

• ✅ Standard 2.54mm Pitch: Fully compatible with universal breadboards and standard PCB layouts.

• ✅ Snappable Design: The 40-pin strip can be easily trimmed or snapped to any smaller size (e.g., 2-pin, 8-pin) to fit your specific design.

• ✅ Gold/Tin Plated Finish: Ensures excellent solderability and long-term protection against oxidation and corrosion.

Technical Specs 🏗️

• Type: Single Row Male Round Pin Header (1x40).

• Pin Count: 40 Pins per strip.

• Vintage Computer Repair: Replacing or upgrading headers on legacy hardware that requires round-pin compatibility.

• Stackable PCB Modules: Creating custom-height board-to-board connections.

Top 3 Customer Questions & Concerns 🙋‍♂️

1. ⚡ Can I use these in a standard breadboard?

   • Yes. The 2.54mm pitch is standard, and the round pins often provide a firmer, more reliable grip in breadboard spring contacts compared to square pins.

2. 🛡️ How do I snap them to size?

   • While round-pin headers are slightly more robust than square ones, they can still be snapped by hand or with a pair of pliers between the plastic insulators.

3. 🔌 Is the 12mm length for the whole pin?

   • Yes, the 12mm refers to the total length of the metal pin. Usually, a small portion (approx 3mm) stays inside the board, while the rest remains available for connection.
