I'm looking for a connector. Ideally it would be a one pin connector mounted on the back side of a board and the pin would come through the board into connector.

Here's an illustration:

Does such a thing exist? And if so what's its name and where can I buy one (or actually about a hundred).

  • \$\begingroup\$ Yes, they exist (although I can't immediately recall what they are called or who makes them). I think, even onesies like that exist. What pin diameter? How much current? \$\endgroup\$ Dec 21 '15 at 21:11
  • \$\begingroup\$ Pins are about 0.3-0.5mm. Current is under 500mA. \$\endgroup\$ Dec 21 '15 at 21:22
  • \$\begingroup\$ through board connector something like this? \$\endgroup\$

  • \$\begingroup\$ @user44635 Almost. That one assumes mounting on the face side of the board and that pin goes through connector and then trough the board. I would like one that's mounted on the back side of the board. But if there's none, this may be an option. Thank you. \$\endgroup\$ Dec 21 '15 at 21:39

If you don't need the connectors to be 100% flush with the board surface, have a look at the PCB socket range by Harwin.

PCB Pins

There's also a range produced by Mill-Max, but I've not had experience with them. I believe Digikey is their main distributor.

PCB Pins

Note that theMill-Max sockets are meant to be pressed in, while Harwin sockets are soldered.

These kinds of connectors are dubbed PCB pin receptacles.

The picture shows a multi-position connection. Single-position receptacles exist too.

Samtec BSW series bottom-entry socket strips might do what you want, although the minimum length shown is 2 pins. They accept .025" square pins.
