Based on the terminology provided, it appears you are inquiring about a specific configuration of a **Category 5e (Cat5e)** ethernet component, likely a patch panel or a modular connector assembly, featuring **RMS** (Rack Mount Space) dimensions and **Shielded** (SLASHD/Shielded) characteristics. In electronics and networking infrastructure, these parts are defined by their physical construction and electrical shielding. ### Component Breakdown | Feature | Specification | Description | | :--- | :--- | :--- | | **Cat5e** | Category 5 Enhanced | Supports frequencies up to 100 MHz and speeds up to 1000 Mbps (Gigabit Ethernet). | | **Shielded (S)** | STP / FTP | Wrapped in conductive foil to protect against Electromagnetic Interference (EMI) and Crosstalk. | | **RMS** | Rack Mount Space | Standardized sizing for 19-inch equipment racks (1 RMS = 1.75 inches in height). | | **Connector** | RJ45 | The physical interface for 8P8C modular plugs. | --- ### Internal Electronic Parts & Materials A shielded Cat5e assembly (like a patch panel or jack) consists of the following internal electronic elements: 1. **Printed Circuit Board (PCB):** * Acts as the medium between the front RJ45 ports and the rear termination points. * Designed with specific trace widths to maintain impedance matching (typically 100 ohms). 2. **IDC Terminals (Insulation Displacement Contacts):** * Usually made of **Phosphor Bronze** with tin plating. * These "punch down" points cut through the wire insulation to create a gas-tight connection with the copper conductor. 3. **Gold-Plated Contacts:** * The pins inside the RJ45 port are typically plated with **50 micro-inches of gold**. * This prevents oxidation and ensures low contact resistance over thousands of insertion cycles. 4. **Shielding Enclosure:** * A nickel-plated or tin-plated brass/steel housing that surrounds the plastic housing. * It provides a continuous ground path from the cable shield to the rack chassis to drain ESD (Electrostatic Discharge). ### Technical Specifications Table | Parameter | Standard Value | | :--- | :--- | | **Contact Resistance** | < 20 mΩ | | **Insulation Resistance** | > 500 MΩ | | **Dielectric Strength** | 1000V AC/DC peak | | **Current Rating** | 1.5 Amps | | **Housing Material** | High-impact, Flame-retardant Plastic (UL 94V-0) | --- ### Implementation Note When using **Shielded (SLASHD)** parts, it is electronically critical that the entire path—from the NIC (Network Interface Card) to the Cable, to the Patch Panel—is shielded and properly grounded. If the ground loop is broken, the shield can act as an antenna, actually increasing interference rather than decreasing it.
