TE Connectivity Solistrand Butt Splice Connector Uninsulated Tin 10 AWG 14.35mm 32151

TE Connectivity 32151 Solistrand butt splice connector is engineered to provide reliable electrical and mechanical performance for a wide variety of wire termination needs in demanding industrial environments. This uninsulated, tin-plated, closed barrel connector is optimized for splicing 10 AWG to 12 AWG copper wires, both solid and stranded. With its butt splice form, the connector allows easy inline joining of wires with minimal resistance and secure mechanical retention.

The body of the 32151 splice is made from fine-grade, high-conductivity copper, ensuring efficient electrical performance. Its bright tin plating offers excellent corrosion resistance for enhanced service life, even in challenging industrial or commercial installations. The closed barrel design, with a brazed seam, ensures uniformly distributed metal strength around the connection and helps prevent conductor pull-out.

The internal surface of the connector’s barrel is either dimpled or serrated, which substantially increases the tensile strength after crimping and maximizes the electrical contact area. This feature is critical for meeting high performance requirements in industrial automation, control panels, power distribution assemblies, automotive harnesses, and commercial wiring projects.

Being uninsulated, the Solistrand 32151 butt splice offers maximum application flexibility in situations where re-insulation or additional protection may be used, and where standard crimping is required across different environments. Its compact length of 14.35 mm and barrel diameter of 5.74 mm facilitate installations in compact enclosures and cable trays, while the 0.99 mm wall thickness offers mechanical durability under industrial stressors.

A wide operating temperature range and compliance with RoHS add to its suitability for many sectors, including manufacturing, electrical contracting, railway, and transportation systems. This connector is used where secure, stable, and efficient wire bonds are essential for long-term reliability, including construction sites, process industries, renewable energy, and heavy-duty commercial equipment.

For optimal installation, it is compatible with standard crimp tools designed for closed barrel connectors. Always follow proper wire preparation and crimping procedures to ensure the best possible mechanical and electrical connection.
