34-position shrouded header, 0.100" pitch
The 66506-052LF: The 4-wall shroud with keying slot guides the mating half and prevents mis-insertion; the push-pull fastening holds the pair without hardware.
Position count across the Quickie series
The 34-position 66506-052LF sits between the 26-position and 40-position members of the same Quickie 66506 series — the 0.100" pitch, dual-row layout, and 4-wall shroud are shared, so the position count alone drives circuit fit.
