The 284514-9 is a shrouded vertical header from TE's Buchanan series — a 9-position, single-level block that mates with the corresponding Buchanan plug to make a wire-to-board terminal block connection. The 0.138" (3.50 mm) pitch sets the board footprint and the per-contact current ceiling; at 11 A per circuit the temperature rise stays within the PA66 housing limit.
Board layout and termination checklist
Through-hole solder termination — the 9 pins drop into a 3.50 mm pitch hole pattern on the PCB. The vertical orientation keeps the header standing upright, so the mating plug approaches from above; plan for the 0.362" (9.20 mm) insulation height when clearing adjacent components or an enclosure lid. The shrouded four-side wall guides the plug into alignment and prevents pin damage during blind mating. Housing is polyamide 6/6 rated UL94 V-0 — the flame rating covers equipment inside an enclosure where the connector is a potential ignition source.
