Header Pin Diameter

On the left is what s known as a stacking header.

Header pin diameter.

A pin header often simply called a header is an electrical connector with one or more rows of exposed male pins set in a plastic base. How to size headers don t leave horsepower on the table get the right sized pipes with these simple tips. Here is one of several 1x03 headers single row three pins. The yellow square posts which are for reference only are drawn with 20 mil sides instead of the standard 25 mils but expanding the sides out to 25 mils and then measuring the distance from the corners to the edge of the hole shows a 3 mil clearance.

A in that picture is the side that goes through your pcb. While straight headers are the norm 90 degree pin headers are also common to accommodate various physical requirements. A pin header often abbreviated as ph or simply header is a form of electrical connector it consists of one or more rows of male pins typically spaced 2 54 millimetres 0 1 in apart but common sizes also include 5 08 millimetres 0 2 in 5 00 millimetres 0 197 in 3 96 millimetres 0 156 in 2 00 millimetres 0 079 in 1 27 millimetres 0 05 in and 1 00 millimetre 0 04 in. In the image above the object on the right is a standard female header that can be soldered onto a through hole pcb.

A header or header connector is often a main junction or connection point for interfacing one piece of equipment or device to another. Additional pin header uses. See all 1 photos. A through hole header has five main dimensions.

Pitch between pins size of the pin length of the bottom side length of the post and length of the top side. The most common are 0 1 pitch 0 025 square pins. A header with female connections is referred to as a header connector. Mouser offers inventory pricing datasheets for 5 mm pin male headers wire housings.
