JST XH connector crimp contacts have the following part numbers:
- SXH-001T-P0.6 (0.08…0.33mm²)
- SXH-002T-P0.6 (0.05…0.13mm²)
- SXH-001T-P0.6N (slighly different shape than the others, see datasheet, 0.13…0.33mm²)
One source to buy them from is LCSC. They have high base shipping costs so if you just want to buy a couple of contacts, you should rather buy a crimp set on Aliexpress or Amazon, but in larger quantities it’s hard to beat LCSC.
