The part number **M5RJ86SPJ-R** refers to a specific series of modular connectors, typically identified as an **RJ45 Modular Jack** manufactured by companies like **Methode Electronics** or similar industrial component suppliers. These are high-performance connectors used primarily in networking and telecommunications. Below is a detailed breakdown of the electronic and mechanical characteristics of this component. --- ## 1. Technical Specifications The following table summarizes the typical electronic profile for this class of RJ45 modular jack: | Feature | Specification (Typical) | | :--- | :--- | | **Connector Type** | RJ45 (8P8C - 8 Positions, 8 Contacts) | | **Mounting Type** | Through-Hole / Right Angle PCB Mount | | **Shielding** | Fully Shielded (Metal Housing) | | **Contact Plating** | Gold over Nickel (often 30µ" to 50µ") | | **Voltage Rating** | 125 VAC RMS | | **Current Rating** | 1.5 Amps | | **Insulation Resistance** | 500 MΩ Min | | **Dielectric Strength** | 1000 VAC RMS (60Hz/1 min) | --- ## 2. Key Electronic Components & Features ### A. Shielding and EMI Protection The "SP" in many of these part numbers often denotes **Shielded Protection**. * **EMI Gaskets:** The metal outer shell acts as a Faraday cage to prevent Electromagnetic Interference (EMI) from affecting the data signal. * **Grounding Tabs:** The "R" suffix often indicates "Rear Tabs" or specific grounding configurations to ensure a solid path to the PCB ground plane. ### B. Contact Integrity The internal pins are made of phosphor bronze and are plated with **Gold**. This is critical for: * **Oxidation Resistance:** Ensuring the connection does not degrade in humid environments. * **Signal Fidelity:** Providing low contact resistance for high-speed data transmission (Cat5e/Cat6 standards). ### C. Orientation (Right Angle) The "RJ86" series is usually a **Right Angle** connector. This means the cable enters parallel to the PCB. This is the standard design for routers, switches, and PC motherboards to allow the port to be accessible from the side/back of the device enclosure. --- ## 3. Physical Attributes * **Housing Material:** High-temperature thermoplastic (UL 94V-0 rated). * **LED Integration:** Some variants in this series include integrated LEDs (Green/Yellow) for link and activity status, though the base "M5RJ86" refers primarily to the mechanical housing. * **Mechanical Durability:** Rated for at least 750 mating cycles. --- ## 4. Common Applications * **Networking Gear:** Hubs, Routers, and Switches. * **Industrial PC:** Embedded motherboards and automation controllers. * **Telecommunications:** VOIP phones and broadband modems.
