PCB Connectors including FFC / FPC, board-to-board, wire to board, crimp style, IDC connectors and moreThe directional features of the housing prevent reverse contact insertion. The housings with two or four circuits have locking mechanisms. This feature provides polarization and prevents mis insertion.Anti-mis insertion featureThe directional features of the housing prevent reverse contact insertion.Locking mechanismThe housings with two or four circuits have locking mechanisms. This feature also provides polarization so that the housing cannot be mismated with the header.
