Based on the standard industry naming conventions and specifications for electronic hardware, the **CONN011-R58** typically refers to a **RJ45 Modular Jack** (Ethernet connector). Below is a detailed breakdown of its electronic and mechanical parts. --- ## 1. Component Overview The CONN011-R58 is a surface-mount or through-hole connector designed for high-speed data transmission, commonly used in networking equipment like routers, switches, and network interface cards (NICs). ### Technical Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | RJ45 (Registered Jack 45) | | **Port Configuration** | 1x1 (Single Port) | | **Number of Positions** | 8 Positions, 8 Contacts (8P8C) | | **Orientation** | Right Angle (Side Entry) | | **Shielding** | Fully shielded (Metal housing for EMI/RFI protection) | | **LED Indicators** | Usually features integrated LEDs (Yellow/Green) | --- ## 2. Key Electronic & Physical Parts ### A. The Housing (Plastic Insulator) * **Material:** High-temperature thermoplastic (e.g., LCP or PBT). * **Function:** Provides the structural frame and ensures electrical isolation between the eight signal pins. It is designed to withstand wave soldering temperatures. ### B. Contact Pins (Signal Path) * **Material:** Phosphor Bronze base. * **Plating:** Gold plating (typically 6µ" to 50µ") over Nickel. * **Function:** The "fingers" that make physical contact with the RJ45 cable plug. Gold plating prevents oxidation and ensures low contact resistance over time. ### C. Shielding (Metal Shell) * **Material:** Copper alloy or Stainless steel with Nickel plating. * **Function:** Acts as a Faraday cage to protect the data signal from external Electromagnetic Interference (EMI) and reduces internal Radio Frequency Interference (RFI). ### D. Integrated Magnetics (Internal Transformer) * *Note: Many "R58" series connectors are "MagJacks".* * **Components:** Small toroidal cores, capacitors, and resistors hidden inside the plastic housing. * **Function:** * **Isolation:** Protects the PHY chip from high voltage spikes on the network line. * **Signal Integrity:** Filters noise and matches impedance (typically 100 ohms). --- ## 3. Pinout Configuration Standard RJ45 pin mapping for Ethernet applications: | Pin # | Signal (T568B) | Function | | :--- | :--- | :--- | | 1 | Transmit+ (TX+) | Differential Data Out | | 2 | Transmit- (TX-) | Differential Data Out | | 3 | Receive+ (RX+) | Differential Data In | | 4 | Unused / POE | Reserved | | 5 | Unused / POE | Reserved | | 6 | Receive- (RX-) | Differential Data In | | 7 | Unused / POE | Reserved | | 8 | Unused / POE | Reserved | --- ## 4. Typical Applications * **Networking:** Modems, Hubs, and Bridges. * **Industrial:** Programmable Logic Controllers (PLCs) and Industrial Ethernet. * **Computing:** Motherboards and Laptop docking stations.
