The **M2AS1-6143-R** is a specific electronic component typically categorized as a **Modular Jack (RJ45)** connector, often featuring integrated magnetics (MagJack). These are commonly used in networking hardware to provide physical connectivity and signal conditioning for Ethernet interfaces. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications | Property | Description | | :--- | :--- | | **Component Type** | RJ45 Connector with Integrated Magnetics | | **Ports** | Single Port (1x1) | | **Orientation** | Side Entry (Right Angle / Horizontal) | | **Shielding** | Shielded with EMI fingers | | **Speed Support** | Typically 10/100/1000 Base-T (Gigabit Ethernet) | | **Mounting Type** | Through-hole (THT) | --- ### 2. Key Electronic Features #### A. Integrated Magnetics (MagJack) Unlike a "dumb" plastic jack, the M2AS1-6143-R contains internal components: * **Isolation Transformers:** Provides electrical isolation (usually up to 1500Vrms) between the PHY chip and the cable, protecting circuitry from static and surges. * **Common Mode Chokes:** Used to suppress electromagnetic interference (EMI) and noise on the differential pairs. * **Termination Resistors:** Usually includes 75Ω resistors (Bob Smith termination) to improve signal integrity and reduce reflections. #### B. LED Indicators Most variations of this part number include integrated LEDs (e.g., Green/Yellow) built directly into the front of the housing. * **Purpose:** Visual feedback for Link status and Data Activity. * **Drive:** Usually requires 20mA current-limiting resistors on the PCB side. #### C. Shielding and Grounding * **Metal Shell:** The outer copper-alloy shell provides a Faraday cage to minimize RFI/EMI. * **EMI Tabs:** Spring-loaded metal tabs ensure a low-impedance connection to the chassis/panel ground. --- ### 3. Pinout and Circuit Schematic The internal wiring follows standard Ethernet mapping. While you must consult the specific datasheet for the manufacturer (often associated with brands like **Maglayers** or **UDE**), the general internal structure looks like this: ```mermaid graph LR A[RJ45 Pins] -- Transformer/Choke -- B[PCB Pins/PHY Side] C[LED Anode/Cathode] -- Internal -- D[LED Control Pins] ``` #### Typical Pin Configuration: 1. **Input (Cable Side):** 8 positions / 8 contacts. 2. **Output (PCB Side):** 10 to 12 pins (including signal pairs, center taps, and LED leads). --- ### 4. Environmental & Material Specs * **Contact Plating:** Gold plating (typically 6µ", 15µ", or 30µ") on the contact area to prevent oxidation. * **Housing:** High-temperature thermoplastic (UL94V-0 rated), suitable for wave soldering. * **Operating Temperature:** Generally -40°C to +85°C (Industrial Grade). ---
