What this 3-position shrouded header fits
284514-3 is a 3-position, single-level vertical header from the TE Buchanan series, designed for terminal block applications on PCBs. The 3.50 mm pitch is common in European-style control wiring, and the 4-sided shroud protects the male pins during handling and mating — a practical feature when the header sits near the edge of a panel-mounted board. Rated 11 A at 300 V, this header handles signal-level power distribution for PLC I/O, sensor interfaces, and small actuator feeds.
Board fit and footprint details
Through-hole solder termination with a vertical header orientation — the pins exit straight up from the PCB, so the mated plug and wires stand perpendicular to the board. The 0.362" (9.20 mm) insulation height gives clearance for the wire entry above the housing, which matters when routing wires in a shallow enclosure. The 3.50 mm pitch sets the board footprint: each pin is spaced 3.50 mm apart center-to-center, matching standard terminal block plugs.
