60-Pin SMT Receptacle for Board-to-Board Stacking
The 20021321-00060T4LF: This is a 60-position, dual-row female socket header from the Minitek127® 1.27mm series by Amphenol ICC (FCI). The 0.050" (1.27mm) pitch and row spacing set a dense footprint — each row carries 30 contacts, and the 0.177" (4.50mm) insulation height gives a low-profile stack height suitable for space-constrained mezzanine connections in telecom or industrial equipment.
SMT Termination and Operating Range
The full 60 positions are loaded, so every pad on the board must be routed. The 1.27mm row spacing means the inner-row traces exit between the rows; a 4-layer board is typical for fan-out at this density.
