High-current plug connectors
Two power contacts carry the load and the signal contacts beside them carry the harness. These are the plug-and-socket sets used in LED light bars, RC packs, e-bike harnesses and panel wiring, priced per piece EXW in US dollars.
How the contact sets are numbered
A 2+9 set is two power pins plus nine signal contacts, so the figure after the plus counts signal contacts, not the total. The catalog carries 2+4, 2+6, 2+8, 2+9 and 3+6 sets, plus the JY-6P and JY-12P, which are straight multi-pin plugs rather than mixed sets.
What the listings publish
Rated current runs from 5 A on the JY-6P to 50 A on the HY2+6Y. Rated voltage is 300 V on the HY contact sets and 12–72 V on the JY-6P. Contacts are gold-plated brass or copper, the JY-12P uses crown-spring sockets on a 3 mm pitch, and the HY sets terminate in solder cups sized for 14–26 AWG wire.
What you get per piece
Each part is priced per piece, at the minimum printed on its own page. A set can be supplied as male pins with a female housing, female pins with a male housing, or matched — those three variants are priced separately because the contact content differs, so compare like with like.
