What this 12-position 3.5mm header does that an open pin header won't
The 1-284514-2: The 4-sided shroud on this Buchanan header protects the male pins from bending during handling and guides the mating plug into alignment — a common failure point with open-pin headers when the board is assembled into an enclosure. With 12 positions at 0.138" (3.50mm) pitch, it mates with standard 3.50mm terminal block plugs, giving you a wire-to-board connection that can be field-serviced without desoldering. Rated 11 A at 300 V (UL), the contact set handles signal-level power distribution — think PLC I/O, lighting controls, or HVAC panels — without derating at room temperature.
Sourcing and lifecycle: active, no LTB watch needed
Supplied in bulk packaging, RoHS3 compliant, with a UL94 V-0 rated housing for equipment inside an enclosure requiring flame resistance.
Mating and termination: what it connects to
Termination is through-hole solder — the vertical orientation keeps the header standing upright on the board during wave or hand soldering. The tin-plated contact mating finish is suited for moderate mating cycle counts (typically 25-50 cycles) in a clean, indoor environment; for higher cycle life or corrosive atmospheres, specify a gold-plated variant in the same series.
