Within the same 77311 base number and identical plating, the 16-position 77311-129-16LF sits between the 10-position 77311-124-10LF and the 36-position 77311-122-36LF. The 16-position variant is the most common density for control and signal I/O on a single row; the 10-position is a compact option for smaller harnesses, while the 36-position fills a dense signal bus.","metaTitle":"77311-129-16LF Amphenol ICC BERGSTIK® Header 16-Pos 2.54mm","metaDescription":"77311-129-16LF BERGSTIK® header, 16 positions, 0.100\" pitch, 3 A, gold mating finish.
