Source for Small Fixed Terminal Connectors?

[SRMcGee]

Folks:

I have a decent supply of project boards and a bunch of 2- and 3-position fixed terminal connectors. All are compatible with 5.08 mm spacing. Many of my fixed terminal connectors have mounting pins that are too large to fit into the holes on the project boards. Virtually all of the things I build on the project boards involve very low current, so I don't have a need for heavy duty terminal connectors. Drilling out the holes is annoying. Can anyone point me towards a supplier for fixed terminal connectors with very narrow pins (ideally smaller than 0.9 mm x 0.7 mm)?

Regards,
Scott

Maybe some exist, but personally would just drill the necessary holes using a 1mm drill. so as to be able to use standard available anywhere ones.
Specially since you already have them.

You are starting with an almost right hole so it takes all of 5 seconds per hole, plus it guides the drill.

Guess your pre-perforated boards have 0.85 or 0.75 mm ones?

1mm seems to be the smallest common size. I have what look like quite tiny pin connectors from ali express, but after checking those are still around 1mm hole

Try Brisk in Mumbai, they have copies of German connectors, many varieties.

No ties to seller, they are made by Calonix here in Baroda, so I know about the product.
They do have agents abroad.

Thanks all! I'll look at Brisk but will also do a little drilling on my next board. It's a little galling -- the holes in the project board are just a mite too small.

Regards.

Calonix has copied a famous German (?) product, look at their website, and then look for similar products in your area.

Frankly, cheap quality in terms of wall thickness and so on.
But you get the idea.
Again, no ties to seller.

Look for 2.54mm pitch terminal block instead, most of them the pin size is about 0.8mm wide.

Phoenix MKDSN when you want one of the best. Real brass, real copper spring, durable. As they have brass/copper leads these can be made thinner with a side cutter.

The Chinese and other knockoffs I throw away with a grin. Often made of plated iron. What a garbage.

CPC or Farnell both in the UK...& both have huge stocks of stuff.....& basically deal with almost all the manufacturing supply side of electronics..& you can usually order just a hand full of things if you wish.
