8-position 3.50 mm vertical header — Buchanan series
The 284516-8 is an 8-position, single-level vertical header from the TE Buchanan series, pitched at 0.138" (3.50 mm) — a common spacing for terminal block interfaces. Rated 11 A at 300 V, with tin-plated phosphor bronze contacts, the header is suited for power distribution and signal wiring in industrial control panels, HVAC equipment, and building automation where the current per circuit stays under 11 A and the voltage under 300 V.
Vertical through-hole mounting with mating flange
Vertical orientation means the header stands perpendicular to the PCB, with a contact tail length of 0.134" (3.40 mm) for through-hole soldering. The mating flange adds a mechanical lock to the plug, resisting vibration-induced disconnection — useful in equipment that sees transport or fan vibration.
