Solder & Crimp Heat-Shrinkable Butt Connectors

Application

The STBT Series combines the mechanical integrity of crimping with the electrical superiority of soldering in a single splice. Each unit features a tinned copper barrel, a low-temperature solder ring, and an adhesive-lined heat shrink sleeve. This "Crimp & Heat" process creates a dual-redundant bond: the crimp anchors the wire against pull-out, while the solder creates a low-resistance current path. Fully sealed against water and corrosion, it is the definitive choice for mission-critical wiring in automotive, marine, and heavy industrial applications.

Series Overview

Available in a comprehensive range of sizes to match various wire gauges. Selection should be based on the conductor cross-section to ensure optimal crimp compression and solder flow. All sizes share the same high-performance construction.

Features and benefits

• Dual Bond: Combines crimp strength with solder conductivity for ultimate reliability.

• PA Sealing: Polyamide adhesive lining blocks moisture and chemicals.

• High Conductivity: Solder fills voids for low resistance and efficient transmission.

• Compliant: The solder rings meet environmental protection requirements.

Notes:

• See tables for detailed dimensions, wire compatibility, and part numbers.

• Custom sizes and color coding available upon request.

• Specifications subject to change; MOQ may vary from standard packs.
