20-position dual-row receptacle for standard 0.100-inch pitch
The 1-534206-0: It's a through-hole solder termination receptacle with a push-pull fastening style, meaning it's meant for a secure but tool-less mate and disconnect cycle. Rated at 2A per contact, this part suits signal-level interconnects where current draw stays modest.
The square pin contact geometry (0.025" square typical) is the industry-standard interface for this pitch class. The glass-filled polyester insulation (UL94 V-0 rated) and black housing with 0.320" (8.13mm) insulation height provide good standoff for cleaning flux residues after wave solder.
