Position count in the BERGSTIK® dual-row ladder
At 46 positions the 77313-122-46LF sits above the 44-position and below the 50-position variants in the same dual-row 0.100" pitch BERGSTIK® family — the footprint, plating options, and UL94 V-0 thermoplastic housing are shared across the series, so the selection axis is circuit count.
