Buchanan 2-Position Right-Angle Header for Terminal Block Systems
The 284541-2 is a 2-position, single-level header from TE Connectivity's Buchanan series, designed for wire-to-board connections in terminal block systems. It uses a 0.150" (3.81mm) pitch, which matches the standard spacing for many 3.81mm pluggable terminal blocks, making it a direct mate for the corresponding Buchanan receptacle. Rated at 11 A per circuit at 300 V (UL), this header can handle up to 22 A total across both positions, though the per-contact current should be derated above 110°C ambient.
Mating Flange and Mechanical Locking
A built-in mating flange on the header provides a positive locking feature with the matching Buchanan receptacle. This mechanical retention prevents accidental disconnection under vibration or cable strain, which is critical in industrial panels, control cabinets, and equipment subject to movement. The flange works with the receptacle's locking tabs to create a secure mated pair; no additional hardware is needed.
Termination is through-hole solder, with a contact tail length of 0.134" (3.40mm) that suits standard PCB thicknesses (typically 1.6mm). The insulation height of 0.285" (7.25mm) above the board surface sets the z-height budget — ensure enough clearance above the header for the mating receptacle and wire exit.
