Choosing the Right Pogo Pin Connectors for My Project

[lucashenry]

Hey everyone,

I’m working on a project that requires reliable Pogo pin connectors for a spring-loaded connection between two PCBs. I need something that can handle frequent connections/disconnections without wearing out too quickly.

Are there specific materials or brands that offer better durability and conductivity? Also, how do I determine the right force rating to ensure a stable connection without excessive pressure?

Any recommendations or experiences with pogo pins in high-cycle applications would be greatly appreciated!

Alignment is critical to prevent tilt which will damage any spring pin. If you design that right 10k cycles no problem.

Show us your alignment design.

Any from big-name manufacturers should be fine.

However, for high cycle usage, you should be using two-part probes, which have carrier sleeves. If a probe is damaged you can just pull it out and fit another one.

Other things to consider are the probe tip shape - you should select that to suit what it will be pressing against on the PCB being tested. eg. A recessed end it it will be against a component pin, or a single point or grid of points for a bare copper test pad.

If it's going to be the same PCB repeatedly, look at pogo pins intended for connectors rather than normal test-point types. Or, off-the-shelf sprung pin / magnetic connectors.

Total spring load, current, displacement, height to support PCB thickness to support pins, pad type (IMG, solder etc) and other factors determine choice.
