Overview

The TE Connectivity 3-1437667-1 is an 8-position dual barrier wire-to-board barrier strip from the Buchanan 4DB Series, engineered for reliable electrical interconnection in industrial and electronic applications. This printed circuit pin terminal block features an 8.26mm (0.325 inch) centerline spacing and a single-row configuration, optimizing space efficiency in compact control panels, machinery, and electronic assemblies. The dual barrier construction ensures secure wire retention and prevents short circuits, while the printed circuit pin design delivers consistent conductivity and durability. Key specifications include a 4-40 screw size with 1.8 lbf-in (0.2Nm) torque rating, compatibility with 22-12 AWG solid or stranded wires, and a wire strip length of 0.18in (4.5mm). The terminal block is constructed from tin-plated brass contacts, galvanized steel screws, nickeled brass clamps, and glass-filled thermoplastic insulators, ensuring long-term reliability in demanding environments. Operating temperature range spans from -40°C to 105°C, making it suitable for harsh industrial conditions. Ideal for applications requiring robust signal and power transmission, such as industrial control systems, electrical distribution panels, and embedded electronics, the 3-1437667-1 delivers secure, organized wiring with minimal installation effort. Its printed circuit pin design allows for easy integration with PCBs, while the dual barrier design enhances safety by preventing accidental short circuits and ensuring proper insulation. Manufactured in the USA by TE Connectivity, a global leader in connectivity solutions, this barrier strip meets rigorous industrial standards for performance and reliability.
