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.

Djula, Thank you very much for your replies. Besides the links, you gave me several new search terms to use. > I hope you find another manufacturer apart from TYCO, please let me know > if you do.

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. Vitaliy

The type we use is a straight pin parallel to PCB and for 1mm PCB thickness. You can see it here: http://www.conrad.de/ce/de/product/733245/LOeTKONTAKTE-SIL-09-11-50-STUeCK They are out of stock, we bought everything they had. Djula

I didn't miss it, I just took it to mean that they were made of some sort of rare unobtanium alloy. > The type we use is a straight pin parallel to PCB and for 1mm PCB > thickness.

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. Vitaliy

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. Djula
