Pitch of a Connector

[Ashley_1319]

What is the “pitch” of a connector?

The pitch is the measurement from the center of one contact to the center of the next contact. The image below shows the measurement of the pitch from contact to contact and between each row. Please note that the pitch between contacts in each row and the pitch between rows are different in this case. They can be the same, but it must always be double checked for a connector with more than one row.

How to get a more accurate measurement when working with small pitch values

Sometimes finding the pitch of a connector is a lot harder than it sounds. Parts keep getting smaller and smaller with the advancements in technologies. Below is a tip that might help your measurements be more accurate and easier to make.

NOTE:

Make sure you are measuring from the correct side of the contact.

A: Pitch
B: Measurement from outside edge of the first pin to the inside edge of the last pin
C: The number of pins

A: 0.5mm
B: 7.5mm
C: 16

\color{red}{A}=\frac{\color{green}{B}}{\color{blue}{C-1}}

\color{red}{A}=\frac{\color{green}{7.5 mm}}{\color{blue}{16-1}}

\color{red}{A}=\frac{\color{green}{7.5 mm}}{\color{blue}{15}}

\color{red}{A}=0.5mm
