Overview

The TE Connectivity Buchanan 6 Series 4-1437652-1 is a 2-position tri-barrier terminal block designed for reliable wire-to-board electrical connections in printed circuit assemblies. This Buchanan 6 Series model features a 9.53 mm [0.375 in] centerline pitch, optimized for compact PCB layouts while maintaining robust electrical performance. The tri-barrier design provides enhanced insulation and protection against accidental short circuits, critical in industrial and electronic systems where signal integrity and safety are paramount. Engineered for printed circuit pin termination, the 4-1437652-1 accommodates 18-22 AWG wire ranges, ensuring compatibility with common industrial and electronic wiring standards. The housing is constructed from UL94V-0 rated polyamide, offering flame resistance and durability in demanding environments. The single-row layout optimizes space utilization on PCBs, making it ideal for applications requiring precise interconnection in compact enclosures. Operating temperature range spans from -40°C to +120°C [-104°F to +248°F], supporting deployment in extreme thermal conditions. Recommended PCB hole diameter is 1.8 mm [0.073 in], ensuring proper alignment and mechanical stability during assembly. This terminal block is part of the Buchanan 6 Series, known for its modularity and ease of installation. The black housing color provides clear visual identification in control panels and industrial equipment. With a UL Class B rating of 15 Amps at 300V and UL Class D rating of 10 Amps at 300V, it meets stringent electrical performance requirements for industrial automation, power distribution, and electronic control systems.
