This connector is a single-row, 40-pin, straight male header strip that can be cut or broken into smaller strips. Both sides of the strip are long, allowing for unique connections that cannot be made with standard male header strips. For example, this header can be used as a female-to-male adapter, and both sides are compatible with wire wrap.

These 0.1″/2.54mm-pitch header strips are commonly used as low-cost connectors. The standard spacing allows use with solderless breadboards, perforated prototyping PCBs, female headers, and our premium and pre-crimped jumper wires. The single-row header strips can easily be snapped into smaller strips to fit your application. The double- and triple-row strips can also be broken into smaller strips, but it takes a little more effort, and it is sometimes easier to use wire/diagonal cutters.

We carry the following 0.1″-pitch breakaway male headers:

1×40-Pin, Straight.

  • 1×40-pin, straight, double-sided (Both sides of the strip are long, allowing for unique connections that cannot be made with standard male header strips. For example, this header can be used as a female-to-male adapter, and both sides are compatible with wire wrap.)
