Synergy 21 S21-COMP-250244 Solder-shrink connector set - waterproof IP67 cable connector content_copy

The solder-shrink connector from Synergy 21 is a waterproof cable connection element, specifically developed for use in demanding environments such as in the automotive sector, on boats, motorcycles, and in outdoor electronics. The product enables a secure, tight, and electrically reliable connection of copper conductors in a single working step. The connection is created by an integrated solder ring, which melts when heated and forms a solid electrical connection. The outer heat-shrinkable sleeve with hot-melt adhesive sealing ensures a reliable seal according to protection class IP67, meaning dust-tight and waterproof, enabling use in outdoor or damp environments. Processing requires no crimping tool, only hot air or a lighter, making installation quick and possible without special tools.

Applications
The connector is suitable for a wide range of applications in the field of vehicle and outdoor electronics. It is frequently used in automotive and motorcycle technology, where vibrations, moisture, and corrosion stress the connections. It is also suitable for marine electronics or mobile devices used outdoors, providing a durable and weather-resistant connection. The various colors and conductor cross-sections allow adaptation to different requirements, from thin signal wires to thicker power supply lines.

Functions and Features in Detail
The connector combines three functions in one component: soldering, shrinking, and sealing. The integrated solder ring ensures an electrically stable connection, while the heat-shrinkable sleeve contracts when heated, releasing the hot-melt adhesive that seals the connection. The colors white, red, blue, and yellow indicate different conductor cross-sections, with the length of the connectors varying between 26 mm and 40 mm depending on the type. Processing involves stripping the wires, twisting the ends, inserting them into the connector, and then heating from the center (solder ring) toward the ends until the solder melts and the adhesive flows out. After cooling, a pull test is recommended to check the strength of the connection.

Technology Explained Simply
The technology is based on the principle of heat shrinking: the sleeve is larger than the conductor in its unprocessed state and shrinks when heated, tightly enclosing the conductor. The hot-melt adhesive integrated into the sleeve melts when heated and forms a tight, waterproof seal. Protection class IP67 means the component is protected against dust and temporary immersion in water, making it suitable for outdoor or damp indoor use. The use of copper conductors is required, as the product is specifically designed for this material.

Compatibility and Accessories
The product is part of a product range from Synergy 21 that includes various waterproof cable connectors. Compatible products include, for example, outdoor cable connectors IP68 1:1 with 2-way or 3-way terminals, waterproof connector boxes with 3 or 4 ports, and indoor cable connectors for 2in-4out or 3in-6out. These components can be combined according to application requirements to create complex cabling solutions. The connection technology is compatible with the mentioned accessories, which are also waterproof and designed for outdoor use.

Installation and Mounting
Mounting involves stripping the conductors, twisting the ends, and inserting them into the connector, ensuring the wires overlap within the solder ring. The connector is then heated with hot air or a lighter from the center (solder ring) toward the ends until the solder melts and the hot-melt adhesive flows out. After cooling, a pull test is recommended to verify the strength of the connection. Processing requires no special tools, making installation particularly simple and fast.

Operational Advantages
The solder-shrink connector provides a durable, waterproof, and corrosion-resistant connection that remains stable even under vibration. The combination of soldering and heat-shrinking technology in a single component reduces installation time and increases connection reliability. Protection class IP67 ensures suitability for use in damp or wet environments, making the product appropriate for outdoor applications. The use of copper conductors is required to ensure electrical conductivity and mechanical strength.
