40Pin 15MM Breakable Pin Header 2.54mm Male Socket

40Pin 15MM Breakable Pin Header 2.54mm Male Socket is a straight male pin header designed for flexible board-to-board and wire-to-board interconnections. The header presents 40 pins on a standard 2.54mm (0.1") pitch with an overall usable length of approximately 15mm per row and is manufactured in a breakable strip format to allow easy trimming to shorter pin counts without special tools.

Its standardized pitch and row spacing make this header compatible with common prototyping platforms, breadboards, perfboards, female header housings, and many PCB footprints used in hobbyist and professional electronics. The breakable design simplifies customization during assembly, enabling you to separate the strip into smaller sections that match connector requirements or board layouts.

Typical applications include connecting microcontroller modules, sensor boards, shields, expansion boards, and jumper-wire assemblies where a reliable, repeatable male connection is required. Installation is generally accomplished by soldering the header pins to plated-through holes or solder pads on a printed circuit board. This header is a straightforward choice when a compact, modular, and reconfigurable pin interface is needed for prototyping, repairs, or low-to-medium volume production.
