Machined Round Pin Male Header 1×40 Break-Away Gold — 2.54mm

Machined Round Pin Male Header 1×40 Break-Away Gold — 2.54mm

A 1×40 break-away machined round pin male header with gold-plated contacts — the premium choice for high-reliability PCB connectors and IC socketing. Precision machined round pins provide lower insertion force, better contact retention, and longer cycle life than standard stamped square pins. Gold plating ensures minimal contact resistance and long-term corrosion resistance. Snaps to any length from 1 to 40 pins — one strip covers all your project needs.

Key Specifications

• Configuration: 1×40 (40-pin, single row, break-away) | Pitch: 2.54mm
• Contact type: Machined round pin (precision turned)
• Contact plating: Gold (Au)
• Current: 3A per pin | Voltage: 250V
• Compliance: RoHS compliant

Machined Round vs Standard Square Pins

• ✅ Machined round pins — precision turned for consistent diameter and lower insertion force into machined sockets
• ✅ Gold plating — superior corrosion resistance and lower contact resistance vs tin-plated headers
• ✅ High cycle life — withstands thousands of mating cycles without degradation
• ✅ Break-away — any length from 1–40 pins from one strip

Typical Applications

• IC socket pins for DIP package socketing on custom PCBs
• Test fixture contact pins for repeated insertion cycles
• High-reliability module socketing requiring frequent removal
• Production PCB assembly with gold-plated machined contacts
• Arduino and microcontroller module socketing
