4 Position Wire to Board Terminal Block Horizontal with Board 0.138" (3.50mm) Through Hole The TE Connectivity 284391-4 is a through-hole mounted PCB terminal block designed for wire-to-board power and signal connections in industrial and electronic control applications. The component belongs to the Buchanan series and features a side-entry wire interface with a horizontal mating orientation. The terminal block supports secure screw-clamp wire termination and is intended for reliable field wiring in low-voltage systems. The connector provides four positions with a 3.5 mm pitch and supports wire sizes from 14 AWG to 30 AWG. The housing is manufactured from polyamide PA66 (Nylon 6/6) with a UL94 V-0 flammability rating. Conductive elements are constructed from brass with tin-plated contacts and nickel-plated clamp and screw components to ensure corrosion resistance and electrical reliability. The device is rated for up to 12 A current and 300 V operation and is suitable for PCB-mounted applications requiring compact, stackable terminal connections. The terminal block includes side interlocking capability for modular multi-position expansion.
