CWT-11 – TYCO ELECTRONICS

The TYCO CWT-11 is a solder sleeve termination designed for wire-to-wire splicing applications. It features a transparent, heat-shrinkable polyvinylidene fluoride (PVDF) or similar fluoropolymer insulation sleeve providing environmental protection and strain relief. An internal solder preform, composed of a tin-lead or lead-free alloy (verify alloy composition based on manufacturing date and RoHS compliance), melts upon application of heat, creating a permanent electrical connection. The integrated sealing rings, typically composed of a thermoplastic adhesive, melt and flow during the heating process, providing a waterproof and environmentally sealed joint. The specified dimensions, 0.425/0.453″, likely refer to the inner diameter range of the sleeve prior to shrinking, indicating compatibility with specific wire gauge ranges, which must be verified against the manufacturer’s datasheet to ensure proper fit and reliable performance. The operating temperature range and shrink temperature are critical parameters that must be adhered to during installation to ensure joint integrity.
