The tin tail is standard for the solder joint. The 10.16mm pitch dictates the board footprint — each position needs about 0.400" of lateral space, which is generous enough that routing a 630V trace between positions is straightforward. The IP20 rating means the housing offers basic finger-probe protection; this is an interior connector for use inside an enclosure, not a sealed outdoor interconnect.
The Dynamic D-5200 series covers power interconnects at the 10.16mm pitch class. The 1-353079-2 is the 2-position right-angle through-hole header variant with selective gold plating. The 4-wall shroud and detent lock are standard across the series, so the mating receptacle from the same pitch family engages correctly.
