3x4pin Bend Pin Header 2.54mm Breakable

3x4pin Bend Pin Header 2.54mm Breakable

• A pin header (or simply header) is a form of electrical connector.
• A male pin header consists of one or more rows of metal pins molded into a plastic base often 2.54 mm (0.1 in) apart.
• Though available in many spacings.
• Male pin headers are cost-effective due to their simplicity.
• Though there are numerous naming variations of male and female connectors.

Reference

In absence of a pin 1 designation on the header, if a designation is missing from the header, the PCB may have a marking indicating orientation (historically, the solder pad around the hole of pin 1 of a THD header is often square rather than round).

For multi-row pin headers the pin number is more complex, because knowing the location of pin 1 doesn’t automatically ensure how the remaining pins are numbered. Typically for headers attached to ribbon cables, the pins are numbered so they go linearly across the cable. Because of the way the connector attaches to the cable, this means in a two-row header, pins in one row have odd numbers and pins in the other row have even numbers.
