Vertical orientation and through-hole solder tails mean the header stands perpendicular to the board. The 0.134" (3.40 mm) tail length is standard for a 1.6 mm PCB — the solder joint wicks up the barrel and forms a visible fillet on the opposite side. In a panel that is wired once and rarely disconnected, tin is the cost-effective choice over gold.
Mating flange and shrouded design
The mating flange provides a screw-down or snap-lock point for vibration-resistant retention — useful in industrial control cabinets where the harness sees occasional tugging. The green color is standard for the Buchanan terminal block family and helps visually identify the connector as a pluggable header on a crowded DIN-rail panel.
Active production, RoHS3, and sourcing posture
How 284516-4 compares to 1-2213934-1
Both are active Buchanan headers in bulk packaging. The key difference is position count: 284516-4 carries 4 positions on a single level, while 1-2213934-1 is a 2-position variant. Pitch, current rating, voltage, orientation, and termination are identical — the same footprint pattern scales by position.
