What this plug does in the assembly
The 284506-6: This is a 6-position plug, part of the Buchanan series, with female sockets that mate to a male header or receptacle on the board. The 3.50 mm pitch spaces the terminals for a compact but serviceable wire entry — tight enough for multi-conductor harnesses, wide enough for a standard screwdriver on the clamp. Rated 11 A at 300 V, it handles moderate power distribution in control panels, lighting, and instrumentation. The tin-plated phosphor bronze contacts keep contact resistance stable under the rated load, though the tin limits the mating cycle count compared to gold — expect a few dozen mate/unmate cycles in field service before the plating wears.
Pitch, positions, and wire-entry layout
Single-level design with 6 positions per level, all on one row. The 0.138" (3.50 mm) pitch sets the centre-to-centre spacing of adjacent terminals — at this pitch, the plug fits standard 3.5 mm terminal block headers. The side-stacking feature lets you gang multiple plugs side-by-side on a rail or header without gaps — useful when you need more than 6 circuits in the same row. The insulation height of 0.437" (11.10 mm) gives clearance for the screw clamp mechanism above the wire entry.
Housing, materials, and environment
Available through independent distribution channels. The part is active, so lead times are typically standard for the series; no pin-compatible direct replacement is listed, so stick with the 284506-6 for existing designs.
