Hi there - I'm looking at making my own magnetic breakaway connector using pogo pins and magnets.

I'm looking to see what pogo pins are available. Digi-Key doesn't seem to sell any - they only seem to sell some really expensive pin headers with built in pogo pins.

So - any suggestions as to where to get these? Ebay looks like a pretty good source - at less than $0.50 each in some places. I do worry about not being able to source the same part again in the future, however.

Also, there are all sorts of different tip styles. Any suggestions as to what tip styles are good for what? I'm planning on using them as part of a magnetic break-away connector. They need to carry a couple amps.

Thanks!

I have dealt with pogo pins before, and if I can give you any advice it would be to avoid them like the plague. They are unreliable, and any slight bend in a pin will likely get it stuck in the housing forever. From my experience they are noisy, and give you a proper contact only half of the time. I suspect this is going to be even worse if you have to carry a couple of amps.

RS stocks spring-loaded test terminals of various types.

If you are lucky you could get some samples from IDI idinet.com, we got some for our bachelor project.

As for tips it depends on what the surface is, if it is always clean and smooth the a flat tip would do the trick, if it is dirty get either a single sharp or a 3x3-spiked head.

Use as short spring distance as possible to prevent bending. And do not use pliers when pulling them out of the receptor, they do deform REALLY easy.

I just got several pogo pins from this guy via ebay
jimmypwfung@gmail.com
he has a good selection
go to ebay and put in pogo pin and you will get several hits (he is user pingfung I think)
if you want to pay $$ you can go to Newark catalog. (at least get an idea of what is "standard")
I am not sure why they don't seem to be available from mouser or digikey.

I'm not sure I'd put 2A through them. They are quite delicate.
I made an ISP spring clip with pogo pins that works well, but the pins are not exposed to much stress.

I dont think 2A will be of much trouble, the resistance in the ones we are using is rated to <8mOhm. You can also get pins especially made for high-current purpose.

That clip is BRILLIANT! I was trying to think of a simple and effective way to hold the pins in for a programming header. Do you find that you have any problems with angle forces?

you can find other solutions described in this thread here: https://www.avrfreaks.net/index.p...

but yes the pins/headers are relatively expensive.

Oh and digi-key does sell individual ones as well. They are also from mill-max, just as the spring-loaded header pis are. I think you have to use "spring loaded" and not "pogo" in your search terms.

The cost of the pins should not be a concern here, as you cannot manufacture them commercially without violating Apple's patent on the connector. So for your one-off creation, who cares if the pins cost 50 cents, or 5 dollars?

Writing code is like having sex.... make one little mistake, and you're supporting it for life.

I bought from this guy as well. The OD size seems to be fairly standard, and he sells receptacles for them, so they are easy to replace.

Not sure how these particular ones are for high currents though. I notice some have fancy designs with odd shaped springs and internal metal balls, etc.

Just ordered 400 from this place, but I'll let you know how it goes:
http://www.digole.com/index.php?productID=494

Has a ton of them for pretty low prices, and seem to have reliable quantities/stock.

I used to run a universal fixture bare board test machine ( part of bare board test service ) and used and recommend Test Connections Inc pins and probes.

same thought here, now at least people have a fresh link where they can order parts when they might be looking for them.

Showed up when somebody googled, so they replied.

I have 6 and still use them.

Since Apple is the only one making cables with magnetic snap releases...

I could keep on going. I'm curious if the patent would hold. Either way, my original question (from many years ago) was not for a mass produced item.
