What This Header Does on a PCB
The 284512-6 is a 6-position, single-level shrouded header from TE's Buchanan series, pitched at 3.50 mm and oriented 90° right-angle to the board. It mates with a Buchanan plug or screw-terminal receptacle to bring field wiring onto the PCB through a solder-terminated through-hole connection. Rated 11 A per contact at 300 V, the header handles moderate power for industrial control signals, sensor loops, and actuator feeds. The 3.50 mm pitch keeps board routing dense enough for multi-circuit runs while still allowing easy hand-wiring in the field.
At 0.138" (3.50 mm) pitch, this header occupies a compact footprint for six circuits on one level. The contact tail length is 0.134" (3.40 mm) — enough for standard 1.6 mm PCBs with good solder-joint standoff. Insulation height sits at 0.287" (7.30 mm) above the board, leaving room under the shroud for the mating plug's latch. Compared to the 10-position sibling (1-2213934-1), this 6-position version suits smaller I/O groups where you don't want to leave half a header unpopulated.
The 11 A rating at 300 V UL is the per-contact maximum in a single-circuit test condition. If the header sees frequent disconnect/reconnect in a corrosive environment, consider a gold-plated variant from the same series.
RoHS3 compliant and packaged in bulk. No official cross-reference exists from TE for this exact part number. The functional alternative 1-2213934-1 shares the same series and pitch but carries 10 positions — confirm your circuit count before substituting.
