Thanks all! --- Quote from: tooki on November 08, 2019, 12:01:33 pm ---Your worry about square pins (or the thick side of these male headers) damaging things is valid: while I've found that breadboards seem to handle it OK (at least if they're of decent quality), if you insert the thick side into a female turned socket, you will permanently damage the socket. I learned this the hard way when fiddling with them. (Luckily, before soldering the sockets into anything!!) --- End quote --- It's not just the damage to the breadboard putting square pins in, I've had plenty of problems pulling them out as well. I had a protoboard that was essentially a 40 pin DIP which I've had to lever out very carefully. (Plugging it in also came with risk of damage to my fingers.) Built up another with the turned pin SIL connectors and it was a lot easier to plug in/out. |

I think they are supposed to be used with female tulip pin headers. Try one and see which side fits best and solder the other one ;) |

Oh, someone mentioned the method of wiring invented by IBM for their mainframes. I very much doubt that in the 21st century someone will produce accessories for this. And these connectors have nothing to do with such a method. The side that has flat pads on the contacts should be adjacent to the board. A flat PCB goes perfectly with flat pads of contacts, in my opinion:) |

So flat side to the board. But what if I want to use them with female machined pin headers? Those longer pins are too loose in mine, and these shorter ones are much better fit for those. |

If you stick the thick end into a female socket then only the thick end will ever work in this socket ;) It's not how they are supposed to be used, but you can. Another abomination I have seen: transmale connectors :scared: Slide a cable into a female socket, solder it in, stick the mounting pins like a male plug into a female socket. |
