The 282811-4 is a 4-position, right-angle, shrouded male pin header from the TE Buchanan series. It mates with a Buchanan plug or receptacle to create a wire-to-board terminal block connection, common in industrial control panels, power supplies, and building automation. Tin-plated copper alloy contacts — tin is the standard choice for moderate mating cycles (50–100) in non-corrosive indoor environments; the 15 A rating at 300 V UL is the full-load limit with proper derating above the 110°C operating ceiling.
Board Fit and Routing — Right-Angle 5.00 mm Pitch
Side interlocking lets you gang multiple 282811-4 headers side-by-side to build a wider terminal strip — the interlock keys snap together without tools.
Confirm the mating part's position count and keying; the 282811-4 has no polarization feature beyond the shroud geometry.
