M3 and up is fairly easily accomodated: http://www.farnell.com/datasheets/47297.pdf
Just search for 'LRB'. They're in stock, perhaps slightly more pricy than you want (be prepared to order a lot more than 100 if you want to drive the price down that low).
M2.5 and M3.5 are typically easily accomodated with washers, although your minimum wire size could be a problem (but who uses <0.5mm² anyway?).
That's amazing, thank you! I was literally about to post a list of JST product codes (I gave up on Stocko, as I have on TE/AMP), when I got the message that a reply had been posted
I found the following on RS:
Metric Stud AWG Area JST Code Packaging
M3 #5 20-18 0.5-1.0mm2 LRB-1.0T-M3 Loose
M3 #5 18-14 1.0-2.5mm2 LRB-2.5T-M3 Loose
M4 #8 20-18 0.5-1.0mm2 LRB-1.0T-M4 Loose
M4 #8 18-14 1.0-2.5mm2 LRB-2.5T-M4 Loose
M5 #10 20-18 0.5-1.0mm2 LRB-1.0T-M5 Loose
M5 #10 18-14 1.0-2.5mm2 LRB-2.5T-M5 Loose
M6 ¼" 18-14 1.0-2.5mm2 LRB-2.5T-M6 LooseThat's a pretty good selection, and I agree no need to support cables <0.5mm
2. These will cover M3-M6 studs, and 0.5mm
2 to 2.5mm
2, which is all I'm ever likely to use. Larger sizes (e.g. for high currents & large SLAs) can be bought when needed, and I'd likely want something heftier for those (i.e. hex crimp tube terminals). I can imagine a need for miniature (M2-M2.5 @ 0.2mm
2 - 0.5mm
2) ring terminals, but that can also wait. The JST terminals are nice as they have a ridged crimp zone for better grip, and thankfully they are (as you point out) available in bulk packaging, so I'll be spared the blistering experience of cutting them from strips.
HOWEVER. Of course there are problems; one being the price (they come in at £0.07 a piece @ 100pcs), which adds up to £50 for the set, plus VAT. Ouch. The other being that the M5 sizes are both back-order items - with an estimated delivery time of... wait for it... November 15th
I will be on site all of November, and that's precisely when I need to have an assortment of crimp terminals to hand, so that's no good. Sigh.
Edit: JST really deserve an award for having
readable product codes that actually make sense. TE/AMP are just awful in this respect; "41332" is 0.51mm tinned brass M4 0.8-2.0mm
2 and "42037-1" is the same but for 0.3-0.9mm
2 - no clue whatsoever.
