What are these pins called? Are they available off-the-shelf?

I was curious, so I went searching. I found something similar but not
exactly the same:

Vitaliy -

Maybe ask Parallax?  They're good guys, within limits :)

I do not know the Pin names but I've seen smaller version of them
(very old SMD to DIP adapter).

Still I do not think this is a good idea. SIP pins (with standard pitch)
are cheaper and widely available. I will think it is also much more
reliable (less problem to break) than the pins used in Basic Stamp.

(ignore the google warning)

I hope you find another manufacturer apart from TYCO, please let me know
if you do.

We had to use a rare type of those in a product for a demanding customer
(oil refinery valves, all parts had to be exactly as specified) and the
manufacturer of the valves had to buy a ridiculous amount of pins from
TYCO, the MOQ was 1,000,000 pins or something like that.

We'll investigate. They certainly look more expensive than the BS2 pins.

SIPs are not ideal for our application, they waste quite a bit more board
space.

Djula,

Thank you very much for your replies. Besides the links, you gave me several
new search terms to use.

Absolutely.

Would the valve manufacturer be willing to sell a few (maybe even tens of)
1000s of these?

Is there anyone else here interested? I think if the order could be split
several ways, it would open up more opportunities.

I can ask them but you missed the "rare type of those" part.

The type we use is a straight pin parallel to PCB and for 1mm PCB
thickness. You can see it here:

They are out of stock, we bought everything they had.

I didn't miss it, I just took it to mean that they were made of some sort of
rare unobtanium alloy.

Very interesting!

BTW, how many languages do you speak?


> They are out of stock, we bought everything they had.

We sometimes do the same thing.  One time we ended up emptying the
inventories of every single distributor we could find, so this one part was
sourced from four or five different suppliers.

These pins are actually quite nice, they are often used on bare glass or
COG LCDs. Despite the looks they are very sturdy, we soldered a few
100.000 of them and I have never seen one crack or break off. Another
good thing is that your PCB looks very much like a DIP package and you
can use the edge of the board which is otherwise unusable.

You don't need any special tooling although I don't know if they are
machine solderable, we soldered them by hand.

The only problem is availability.
