20 Positions, 1.27mm Pitch — Board-to-Board Signal Link
The 20021112-00020T4LF: This is a 20-position, dual-row unshrouded header on 0.050" (1.27mm) pitch, from Amphenol ICC's Minitek127 series. That wide thermal window suits equipment that sees thermal cycling — industrial control cabinets, test fixtures, or telecom line cards.
Right-Angle Routing — Board-Edge Fit
Unshrouded push-pull fastening means there's no locking latch; vibration resistance depends entirely on the mating receptacle's retention force. Row spacing is also 0.050" (1.27mm), so the dual-row footprint is compact — 0.100" (2.54mm) overall width across both rows. The contact length after the bend is 0.106" (2.69mm) post, which gives a reasonable solder fillet height on a standard 1.6mm board.
It's RoHS compliant.
Position Count vs Siblings — 20 vs 16 vs 12
The 20021112-00020T4LF is the 20-position variant in the Minitek127 right-angle unshrouded header family. Direct peers include the 20021112-00016T4LF (16 positions) and 20021112-00012T4LF (12 positions) — same pitch, same gold mating finish, same 1 A rating. The only difference is the pin count, so the footprint length scales accordingly. If the BOM calls for 16 circuits, the 16-position sibling is a drop-in fit on the same row spacing.
