Right-angle shrouded header for terminal block wiring
The 284512-4 is a 4-position, single-level header from TE's Buchanan series, designed as the board-mount half of a 3.50mm-pitch terminal block interface. Rated 11 A at 300 V (UL), it suits signal-level power distribution in industrial panels, PLC I/O modules, and building automation. The shrouded housing with four-side enclosure protects pins during handling and prevents accidental shorting.
Pitch, positions, and PCB footprint fit
At 3.50mm pitch, this header matches standard Buchanan pluggable terminal blocks (e.g., 796xxx series). The 4-position count is common for small sensor/actuator interfaces or power supply outputs. Contact tail length is 0.134" (3.40mm) for through-hole soldering into a standard PCB. The tin mating finish is cost-effective for fixed-installation environments.
