Overview

The TE Connectivity Buchanan 4DB Series 4-Position Dual Barrier Strip (SKU: 2-1437667-6) is a precision-engineered wire-to-board connector designed for reliable electrical interconnections in industrial, automation, and control panel applications. This 4-position barrier strip features an 8.26mm (0.325 in) centerline spacing, ensuring precise alignment and secure termination for both solid and stranded wires. The dual barrier design provides enhanced insulation and protection, reducing the risk of short circuits and improving system reliability in demanding environments. Constructed with a polyamide body, tin-plated brass terminals, and nickel-plated brass clamps, this connector delivers robust mechanical strength and corrosion resistance. Gold-plated copper alloy contacts ensure low contact resistance and long-term signal integrity, while glass-filled thermoplastic insulators provide superior electrical isolation. The connector supports wire sizes from 26-16 AWG (0.14–1.5 mm²) and accommodates a wire strip length of 0.18in (4.5mm). With a screw torque rating of 1.8 lbf-in (0.2 Nm) and a screw size of 4-40, installation is straightforward and secure. Ideal for use in control panels, power distribution systems, industrial machinery, and automation equipment, the Buchanan 4DB Series barrier strip meets stringent industrial standards for durability and performance. Its compact design maximizes space efficiency while maintaining high-performance electrical connectivity. Manufactured in the USA by TE Connectivity, a global leader in connectivity solutions, this barrier strip is backed by rigorous quality assurance for long-term reliability.
