The keying slot in the shroud polarises the mate so the socket can only go on one way; a mis-keyed pair won't seat, which is the right failure mode compared to a reversed connection. The part is RoHS compliant.","metaTitle":"66506-051LF Header 26POS 2.54mm Quickie™ Amphenol ICC (FCI)","metaDescription":"66506-051LF Amphenol ICC (FCI) Quickie™ series 26-position dual-row shrouded header. 0.100\" (2.54mm) pitch, 30.0µin gold plating.
