Overview

The TE Connectivity Buchanan 8 Series 8-1437657-8 Tri-Barrier Barrier Strip is a 5-position, single-row wire-to-board connector engineered for reliable electrical connections in industrial and electronic assemblies. This barrier strip features an 11.1 mm [0.438 in] centerline spacing with a 0.375" [9.53 mm] pitch, designed for direct integration with printed circuit boards via printed circuit pins. The Tri-Barrier design provides enhanced insulation and mechanical protection, preventing short circuits and ensuring long-term operational integrity in demanding environments. The connector accepts 18-22 AWG wire and is rated for 15 Amps at 300V (UL Class B) or 10 Amps at 300V (UL Class D), evaluated to U.S. and Canadian standards. Recommended PCB hole diameter is 1.8 mm [0.073"], with a tightening torque of 12 in.-lb. for secure terminations. Operating temperature range spans -40°C to +120°C [-104°F to +248°F], making it suitable for harsh industrial applications. The Buchanan 8 Series is modular and compatible with accessories like covers and vertical mount options. Typical applications include control panels, industrial machinery, automation systems, and complex electronic assemblies where secure, dependable wire-to-board connectivity is critical. The 8-1437657-8 ensures signal integrity and electrical safety while simplifying assembly processes and reducing maintenance requirements.
