This triple-row, 120-pin (3×40) right-angle male header strip with 0.1" (2.54mm) pitch is a versatile connector for electronics projects. The breakaway design lets you snap or cut it into any triple-row length you need, and the right-angle orientation is ideal for low-profile connections where vertical clearance is limited.
Standard 0.1" pitch ensures compatibility with solderless breadboards, perfboards, PCB footprints, and female header sockets. Triple-row strips can be broken into smaller sections, though using diagonal cutters is recommended for a cleaner cut.
Key Features
- 3×40-Pin (120 pins total) – Breakaway design, snap or cut to any triple-row length
- Right-Angle Orientation – Low-profile connections parallel to the board surface
- 0.1" (2.54mm) Pitch – Industry-standard spacing for broad compatibility
- Male Header Pins – Mates with standard female headers and breadboards
Ideal For
- High-density board-to-board connections
- Prototyping and PCB projects requiring triple-row headers
- Low-profile multi-row connector applications
Package Contents
- 1× 3×40-pin right-angle breakaway male header
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
