The **S02-07-R-92** is a specific part number belonging to the **S02 series** manufactured by **TE Connectivity (Raychem)**. These components are technically known as **SolderSleeve Shield Terminators**. They are designed to provide a permanent, insulated, and strain-relieved electrical connection between a braid (shield) of a coaxial cable or shielded wire and a ground lead. --- ### 1. Technical Specifications The part number encodes specific dimensions and material properties. Here is the breakdown of the physical and electrical characteristics: | Feature | Specification | |:---|:---| | **Manufacturer** | TE Connectivity / Raychem | | **Product Type** | SolderSleeve Shield Terminator | | **Material** | Polyvinylidene fluoride (PVDF) Heat-shrinkable sleeve | | **Solder Type** | Sn63 Pb37 (with ROL1 flux) | | **Temperature Range** | -55°C to +150°C | | **Pre-installed Lead** | No (R-92 refers to the specific size/configuration) | | **Environmental Protection** | Immersion resistant (Moisture/Waterproof) | --- ### 2. Component Composition A SolderSleeve consists of four primary integrated elements: 1. **Heat-Shrinkable Sleeve:** Transparent plastic tubing that shrinks when heated to provide insulation and strain relief. 2. **Solder Preform:** A ring of solder (with flux) located in the center. When heated, it melts to create a 360-degree electrical bond between the shield and the ground wire. 3. **Thermoplastic Sealing Rings:** Colored rings at both ends of the sleeve that melt and flow to provide an environmental seal against moisture. 4. **Temperature Indicator (Optional):** Many in this series include a thermochromic dye that changes color when the correct soldering temperature has been reached. --- ### 3. Usage & Application The **S02-07-R-92** is primarily used in aerospace, defense, and high-reliability industrial applications. #### Installation Process: * **Step 1:** The shield of the cable is stripped, and a ground wire is placed against it. * **Step 2:** The SolderSleeve is slid over the junction. * **Step 3:** A heat gun (reflow tool) is used to shrink the tubing and melt the solder. * **Step 4:** The solder flows into the braid, creating a low-resistance connection, while the ends seal the assembly. --- ### 4. Advantages * **Consistency:** Eliminates the variability of manual soldering. * **Space Saving:** Low profile compared to traditional mechanical connectors. * **Durability:** The PVDF sleeve provides high resistance to chemicals and abrasion. * **Inspection:** The transparent sleeve allows for easy visual inspection of the solder joint.
