Three-position right-angle header for 3.50mm terminal blocks
The 284539-3 is a 3-position, right-angle, shrouded header from TE's Buchanan series, designed to mate with 3.50mm pitch pluggable terminal blocks. The 0.138" (3.50mm) pitch sets the board footprint — each position is on a 3.50mm grid, which is standard for compact signal or low-power distribution. Rated 11 A at 300 V per UL, this header handles moderate current for control signals, sensor inputs, or auxiliary power in industrial equipment.
Right-angle orientation and board integration
The through-hole solder tails are 0.134" (3.40mm) long, and the insulation height above the board is 0.285" (7.25mm). A mating flange on the header provides a positive lock with the matching plug housing, reducing the risk of vibration-induced disconnection.
