40x2 20mm 2.54mm Male Pin Header

A 2×40 (dual-row) male pin header with 20 mm pin length, designed for through-hole PCB mounting where extra clearance, stacking height, or deeper socket engagement is required. The standard 2.54 mm (0.1″) pitch ensures wide compatibility with breadboards, prototyping PCBs, microcontroller boards, and IDC connectors. The strip is breakable, so it can be cut to any required pin count.

Technical Specifications:

• Pin configuration: 2 × 40 (80 pins total)
• Pitch: 2.54 mm (row & column spacing)
• Pin length: 20 mm
• Mounting type: Through-hole (THT)
• Contact material: Brass (typically tin/gold plated)
• Insulator: Black plastic
• Breakable: Yes

Features:

• Longer 20 mm pins for board stacking and thick enclosures
• Dual-row design for higher signal density
• Strong mechanical stability compared to single-row headers
• Easily snapped into smaller sections

Applications:

• Stacked Arduino / development boards
• Expansion shields and backplanes
• IDC ribbon cable connections
• General electronics prototyping and production PCBs
