The **K-C6-R** typically refers to a high-performance, Category 6 (Cat6) shielded RJ45 keystone jack or connector, often used in networking infrastructure. It is designed to handle high-speed data transmission while minimizing electromagnetic interference (EMI). --- ### 1. Key Technical Specifications The following table highlights the primary electrical and physical characteristics of the K-C6-R component: | Feature | Specification | | :--- | :--- | | **Category** | Cat6 (Gigabit Ethernet) | | **Connector Type** | RJ45 (8P8C) | | **Shielding** | STP/FTP (Shielded) | | **Frequency Range** | Up to 250 MHz | | **Data Rate** | Up to 1000 Mbps (1 Gbps) | | **Termination Style** | 110 Punch Down or Toolless | | **Contact Plating** | Gold Plated (often 50μ) | --- ### 2. Internal Electronic Construction The K-C6-R is more than just a plastic housing; it contains several critical electronic sub-components: #### A. Lead Frame & Spring Contacts * **Material:** Phosphor bronze base with gold plating. * **Function:** Ensures a low-resistance connection with the RJ45 plug. The gold plating prevents oxidation (corrosion) over time, which is vital for maintaining signal integrity. #### B. Integrated PCB (Printed Circuit Board) Inside the jack, there is a small PCB that manages the "crosstalk" compensation. * **NEXT/FEXT Management:** As frequencies reach 250MHz, signals can "bleed" between pairs. The PCB layout uses specific traces to cancel out this interference. #### C. IDC (Insulation Displacement Contacts) * **Function:** These are the "V" shaped metal tines where the solid copper wires from the network cable are pressed. * **Mechanism:** They pierce the plastic insulation of the wire to create a gas-tight cold weld with the copper core. #### D. Shielding (The "R" and "C" variants) * **Metallic Housing:** The outer shell is usually a nickel-plated zinc alloy. * **Grounding:** It provides a 360-degree shield that connects the cable's foil/braid to the patch panel's ground, protecting the data from external EMI/RFI. --- ### 3. Wiring Configuration The K-C6-R supports both T568A and T568B wiring standards. ```text Standard T568B Wiring Order: 1. White/Orange 2. Orange 3. White/Green 4. Blue 5. White/Blue 6. Green 7. White/Brown 8. Brown ``` --- ### 4. Applications * **Data Centers:** High-density patching where shielding is required to prevent "Alien Crosstalk" between adjacent cables. * **Industrial Environments:** Areas with high electrical noise (motors, fluorescent lights). * **POE+ Support:** Designed to handle Power over Ethernet (IEEE 802.3at) without excessive heat buildup at the contact points.
