5-position vertical header for 3.81mm pitch terminal blocks
The 284519-5 is a 5-position, single-level vertical header from TE's Buchanan series, designed for wire-to-board terminal block applications. Its 0.150" (3.81mm) pitch and shrouded (4 side) profile provide keyed alignment and pin protection during mating with the corresponding plug. Rated at 11 A and 300 V per UL, this header suits control cabinet, panel wiring, and industrial I/O signal distribution where a compact 5-circuit interface is needed. The vertical orientation keeps the wire entry axis perpendicular to the PCB, simplifying routing in tight enclosures.
Pitch, position count, and current rating
The 3.81mm pitch is a common spacing for 300 V class terminal blocks, balancing board density with clearance for 16–22 AWG wire. At 11 A per circuit, the header can handle moderate power loads — typical for sensor, actuator, or power supply outputs — without exceeding the 110°C operating limit of the PA66 housing. The mating flange feature adds mechanical retention when paired with the matching plug, reducing vibration-induced disconnection.
