50-Position SMT Header for Dense Board-to-Board Stacks
The 20021121-00050T4LF: At 1A per contact with a 125VAC rating, the current limit is set by the contact geometry and the 10µinch gold mating finish — adequate for signal-level loads and low-power interconnects within a single enclosure. The surface-mount termination and push-pull fastening type mean this header is reflow-soldered to the board and mates without a locking latch — suitable for applications where the mated pair is not subject to continuous vibration or cable strain.
Gold Mating Finish and Flame-Rated Housing
The same Minitek127® 1.27mm dual-row SMT header is also available in 40-position (20021121-00040T4LF) and 60-position (20021121-00060T4LF) variants, with identical pitch, plating, and material specs. The 50-position version sits between these two — the choice is driven by the required signal count on the board edge. For buyers needing tape-and-reel packaging instead of tube, the 20021121-00050C4LF offers the same 50-position header in a reel format suitable for automated pick-and-place assembly.
