Buchanan Header for Terminal Block Wiring
The 1776166-8: Rated 12 A at 300 V per UL, the header handles moderate power distribution within a single connector. The tin-plated mating finish suits applications with infrequent reconnection — typical for terminal block headers that stay mated for the equipment life.
Dual-Level Layout and Side Interlocking
Two levels of 8 positions each stack vertically, doubling the circuit count in the same board footprint as a single-level 8-position header. The insulation height of 0.902" (22.90 mm) accounts for the dual-level body, so the z-height budget on the PCB must accommodate this. Side interlocking features allow multiple 1776166-8 headers to be ganged side-by-side into a single multi-position assembly — useful when a panel requires more than 16 circuits on the same pitch. The interlocking tabs snap together without tools, maintaining alignment across the joined headers.
