40x2 10mm 2.54mm Male Pin Header

A 2×40 (dual-row) male pin header with 10 mm pin length, designed for compact, high-density through-hole connections. With the standard 2.54 mm (0.1″) pitch, it is fully compatible with breadboards, IDC connectors, and common development boards. The header is breakable, allowing it to be cut into smaller sections as needed.

Technical Specifications:

• Pin configuration: 2 × 40 (80 pins total)
• Pitch: 2.54 mm (row-to-row and pin-to-pin)
• Pin length: 10 mm
• Mounting type: Through-hole
• Contact material: Brass (tin or gold plated, depending on batch)
• Insulator color: Black
• Breakable: Yes

Features:

• Dual-row layout for higher pin density
• Standard 10 mm pin length for low-profile PCB assemblies
• Strong mechanical stability due to two-row structure
• Can be snapped into required pin counts

Applications:

• Microcontroller and FPGA boards
• IDC ribbon cable headers
• Shield stacking and expansion boards
• General PCB prototyping and production designs
