Vertical 4-Pin Terminal Block Header
The 284519-4: This is a 4-position, single-level, vertical-mount header from TE's Buchanan series, designed for wire-to-board terminal block applications. The 0.150" (3.81mm) pitch and shrouded (4-side) housing protect the male pins during handling and mating. Rated 11 A at 300 V (UL), it suits control panels, industrial automation, and power distribution blocks where a compact, keyed header is needed.
The 3.81mm pitch is a common terminal block spacing — the 4-position header occupies roughly 15.24 mm of board edge. The vertical orientation means the mating plug inserts straight down, keeping the assembly height above the PCB to 0.362" (9.20mm) insulation height. Contact tail length is 0.134" (3.40mm), typical for through-hole soldering into a standard 1.6 mm PCB. The mating flange feature provides a mechanical lock to the plug housing.
