The **FJT-56-R** is an electronic component primarily classified as a **RJ45 Modular Jack Connector**. It is designed for PCB (Printed Circuit Board) mounting and is commonly used in networking hardware for Ethernet connectivity. --- ### 1. Technical Specifications The "FJT-56-R" typically follows standard industry specifications for 8P8C (8 positions, 8 contacts) connectors. | Feature | Specification | | :--- | :--- | | **Type** | RJ45 Modular Jack | | **Configuration** | 8P8C (8 Positions, 8 Contacts) | | **Orientation** | Side Entry (Right Angle / Horizontal) | | **Mounting Type** | Through-Hole (THT) | | **Shielding** | Non-Shielded (Usually) | | **Contact Plating** | Gold over Nickel | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Physical Characteristics * **Housing Material:** High-temperature thermoplastic (usually UL 94V-0 rated). * **Contacts:** Phosphor bronze base with selective gold plating to ensure high conductivity and corrosion resistance. * **PCB Tail:** Solder tails designed for standard PCB thickness (approx. 1.6mm). * **Tab Direction:** Typically "Tab Down," meaning the locking clip of the RJ45 cable points downward when inserted. --- ### 3. Key Electronic Functions * **Signal Integrity:** Designed to handle data rates consistent with Category 5 (Cat5) or Category 5e (Cat5e) cabling. * **Insulation Resistance:** Usually rated at a minimum of 500MΩ to prevent leakage between pins. * **Contact Resistance:** Low resistance (approx. 20mΩ - 30mΩ max) to minimize signal loss. * **Voltage/Current Rating:** Typically rated for 125V AC/DC at 1.5 Amps. --- ### 4. Common Applications The FJT-56-R is found in various telecommunication and networking devices: 1. **Network Switches/Routers:** Providing the physical port for LAN cables. 2. **Industrial Controllers:** Enabling Ethernet communication for PLCs or IoT gateways. 3. **Consumer Electronics:** Smart TVs, game consoles, and desktop motherboards. 4. **Modems:** For broadband internet input/output. --- ### 5. Identification Code Breakdown While naming conventions vary by manufacturer (such as Full Rise or similar vendors), the code generally breaks down as follows: * **FJT:** Series identifier (Modular Jack). * **56:** Specific mechanical body style/size. * **R:** Usually denotes **RoHS Compliance** (Lead-free).
