Connector Plugs for Thin (Magnet) Wires

I received the .05” header strips yesterday, 10 days is very fast from China.  I’m very impressed with the size.  I was able to remove the pins for polarizing the connectors.  The only things I don’t like are losing a pin for each cut and the price per pin is way up there, 4¢ per pin.



Thanks for the info!  The tiny connectors will come in handy for automation projects.  I think I’ll stick with the .1”/2.54mm headers for normal stuff.

I use this company for all my connector needs. https://www.peconnectors.com/

They have a huge selection of connectors and they are pretty easy to sort through. 

most ardiuno stuff is .1" (2.54mm) spacing.

Hope this helps.

Mel, that is all I use. The round pins & sockets. 1.27MM. IF I need to index- I use one pin for indexing. Cut off the pin and solder close the matching socket-

 

That’s the way I did the larger connectors until I figured out I could swap pins.  I’m going to order some today.

Thanks for the info.
 

EDIT:

Expensive little buggars.  $20.34 S&H + State Tax for 3 each, 50 pin male & 50 pin female. 6.78¢ per pin.  The 2.54mm headers are 1.4¢ per pin.

EDIT 2:

There are 5 headers per package for $20.34 or 4¢ per pin.

Thanks, everyone, for your help.

I am going to order several different kinds and see which I like the best.  They are all very cheap.

At times like this, I wish we still had electronics stores nearby with products that one could pick up and look at.

Thanks again.

The pin & socket that Mel showed is based on a NEM 652 which has a pin spacing of 2.54 MM. There is also a plug and socked based on the NEM 651 which has a pin spacing of 0.05 between the pins. Some DCC suppliers stock these in 40 pin single row headers which you can cut to a length you need. Much smaller than the 652.

 

I was wondering about the .05”/1.27mm header strips, have you tried any of them?  I prefer the round pin .1”/2.54mm connectors mainly because you can easily swap the pins to make polarized connectors.

I do use the square pin (Arduino type) for structure lighting but really like the round pin for passenger car lighting.  All of my structure lighting is incandescent so polarity isn’t important.  I have cut over to LEDs in my passenger cars so polarity is important.

I have been kicking around getting some .05”/1.27mm headers and found a vender on eBay for the round pin but haven’t gone there yet.

They don’t look like the pins are swappable for polarization protection.

assuming you want to connect the wire into a header on an arduino mounted under the layout.

i've soldered thin 30g wires to cut off resistor leads and just pushed the soldered leads into the arduino header.

The best connectors I’ve found for small wires are the 2.54mm/.1” Header Strips.  They can be cut to any contact configuration.

https://www.ebay.com/itm/Header-Strip-Connector-40Pin-2-54mm-Round-Male-Female-Single-Double-Straight-US/253823347087?ssPageName=STRK%3AMEBIDX%3AIT&var=553112779320&_trksid=p2060353.m1438.l2649

They end up about 2¢ per pin.

I'm connecting some Arduino circuits using thin magnet wires.  I want to be able to connect and disconnect the wires using some sort of plugs.  These wires will be running under the layout.

I don't want to solder these wires, since I may be connecting or disconnecting different wires.

Does anyone know of some good connectors for magnet wires?
