The tin-plated mating surface suits moderate-cycle, non-corrosive environments. For higher cycle life or aggressive atmospheres, the CT series also offers gold-plated options — but for a general-purpose board-to-wire interconnect inside an enclosure, tin carries the signal without the cost premium.
The 0.126" (3.20 mm) post length fits standard 1.6 mm PCBs; the 0.177" (4.50 mm) mating pin length engages the receptacle contact beam fully.
Mating and sourcing — CT series receptacle
This header mates with TE CT series crimp-type receptacle housings — look for the matching 10-position single-row housing (e.g., 1-292215-0 or similar) and the corresponding tin-plated crimp terminals (part numbers in the 292133 range).
