The **M2RS1-1F-R** is a specific electronic component, typically categorized as a **modular connector** or a **network interface component** (often associated with RJ45 MagJack or high-speed data connectors). These parts are designed to integrate physical connection ports with internal signal conditioning. --- ### 1. Key Technical Specifications Below is a breakdown of the typical physical and electrical characteristics for this series: | Parameter | Description | | :--- | :--- | | **Component Type** | Modular Jack (RJ45) / Magnetic Connector | | **Configuration** | Single Port (1x1), Right Angle | | **Shielding** | Metal Shielded (EMI protection) | | **Mounting Type** | Through-hole (THT) | | **LEDs** | Often features integrated Status LEDs (Green/Yellow) | | **Termination** | Solder | --- ### 2. Functional Electronic Parts The "R" in the suffix usually denotes **RoHS Compliance**, while the "1F" identifies the internal circuitry configuration. The internal architecture typically includes: #### A. Magnetics (Transformers) Inside the housing, there are tiny toroidal transformers. These provide: * **Galvanic Isolation:** Protects the rest of the PCB from external voltage surges. * **Impedance Matching:** Ensures the signal integrity between the PHY (Physical Layer) chip and the cable. #### B. Common Mode Chokes Used to suppress Electromagnetic Interference (EMI). They filter out high-frequency noise while allowing the data signals to pass through cleanly. #### C. Integrated Resistors/Capacitors These passive components are built-in to handle "Bob Smith Termination," which helps reduce common-mode noise and manages emissions on unused wire pairs in Ethernet applications. --- ### 3. Pinout and Physical Layout While specific pinouts can vary by manufacturer (like Pulse, Bel, or Abracon), the layout generally follows this logic: ```text [ Front View ] [ PCB Footprint ] ______________ 8 7 6 5 4 3 2 1 | __________ | o o o o o o o o | | | | | | RJ45 | | [LED Pins] [Shield Tabs] |_|__________|_| o o [ ] [ ] ``` --- ### 4. Typical Applications * **Networking Gear:** Switches, routers, and hubs. * **Industrial PC:** Motherboards and embedded systems. * **IoT Devices:** Providing wired internet connectivity to smart controllers. ---
