0.100" Pitch and Polarizing Key — Board Fit and Orientation
The dual-row layout packs 20 positions into a 10-per-row format that keeps the cable width manageable. A feed-through slot and polarizing key on the housing ensure the receptacle mates only with the matching slotted header; reversed or offset insertion is physically blocked, which saves a mis-wired harness from reaching test.
It is ROHS3 Compliant, so it ships into RoHS-regulated regions without exemption paperwork.
Termination and Mating — IDC Press and Header Match
The polarizing key and feed-through slot on the receptacle align with the matching slot on the header; if the header lacks the slot, the connector will not seat.
