8-Position, Two-Level Right-Angle Header at 5.00 mm Pitch
The 1776166-4 is an 8-position, two-level right-angle shrouded header from TE's Buchanan series, on a 5.00 mm pitch — the two levels stack 4 positions per level, saving board edge space compared to a single-row 8-position header. Rated 12 A at 300 V, this header suits signal-level power distribution in industrial control panels, PLC I/O modules, and terminal block interfaces where the 5.00 mm pitch matches standard terminal block spacing.
Side Interlocking for Multi-Header Ganging
The interlocking side feature lets you mechanically link multiple 1776166-4 headers side-by-side to create a wider multi-position assembly — useful when a single header doesn't cover the required circuit count, without custom tooling. Compared to a single-level sibling like 1776038-5 (5 positions, 5.08 mm pitch, 15 A), the 1776166-4 offers two levels at a slightly tighter 5.00 mm pitch, trading per-contact current for density in a right-angle board-edge layout.
RoHS3 compliant and housed in UL94 V-0 polyamide, it meets the flammability and material restrictions for equipment inside an enclosure.
