Termination is listed as press-fit and solder, meaning the through-hole tails are designed for a press-in fit before wave soldering — common for high-retention headers in vibration-prone assemblies.
Current rating is 3 A per contact at 250 V, with a natural (uncolored) PA66 housing rated UL94 V-0.
The pitch is 0.098" (2.50 mm) and the pin count is 2 positions, single row, all loaded.
