Overview

The TE Connectivity 3-1437667-3 is a 10-position dual barrier wire-to-board barrier strip from the Buchanan 4DB Series, designed for reliable electrical connections in industrial and electronic applications. This barrier strip features an 8.26mm (0.325 in) centerline spacing, ensuring precise alignment and secure connections in compact spaces. The dual barrier design provides enhanced insulation and protection against short circuits, making it ideal for demanding environments where electrical isolation is critical. Engineered for durability, this barrier strip supports wire-to-board connections with a single-row configuration, maximizing space efficiency while maintaining high-performance electrical connectivity. The printed circuit pin design allows for easy integration with PCBs, enabling the addition of components like LEDs or resistors as needed. Key specifications include a body material of polyamide, tin-plated brass terminals, and gold-plated copper alloy contacts for superior conductivity and corrosion resistance. The terminal clamp is nickeled brass, and insulators are glass-filled thermoplastic for added strength and thermal stability. The strip supports wire sizes from 22 to 12 AWG, with a recommended wire strip length of 0.18 in (4.5 mm). With a temperature range of -40°C to 105°C and a screw torque of 1.8 lbf-in (0.2 Nm), this barrier strip is suitable for use in control panels, power distribution units, industrial machinery, and other critical applications. The 4-40 screw size ensures compatibility with standard mounting hardware. Manufactured by TE Connectivity, a global leader in connectivity solutions, the 3-1437667-3 meets rigorous industrial standards for reliability and performance. Its robust construction and precise engineering make it a dependable choice for engineers and technicians seeking long-lasting electrical interconnection solutions.
