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, minimum from 50 pieces per model. 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.
