The **M6SPP-A1PR-R** is a high-performance, shielded M12 D-Code to RJ45 industrial Ethernet cable assembly, typically manufactured by companies like **METZ CONNECT**. It is designed for reliable data transmission in harsh industrial environments. --- ### 1. Key Technical Specifications The following table highlights the primary electronic and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Connector A** | M12 Plug (Male), D-Coded, 4-Pole | | **Connector B** | RJ45 Plug (Shielded) | | **Data Rate** | Fast Ethernet (10/100 MBit/s) | | **Shielding** | S/FTP (Braided shield + foil wrapped pairs) | | **Cable Jacket** | PUR (Polyurethane) - Halogen-free | | **IP Rating** | IP67 (M12 side) / IP20 (RJ45 side) | | **Standard** | Cat5e | --- ### 2. Electronic Component Breakdown #### A. M12 D-Coded Connector The M12 interface is the industrial standard for sensor/actuator connectivity. The **D-Coding** specifically designates it for Ethernet use, featuring 4 pins that handle transmit and receive signals. * **Mechanical Integrity:** Threaded locking prevents accidental disconnection due to vibration. * **Protection:** Provides a dust-tight and waterproof seal (IP67). #### B. S/FTP Cable Construction The "S/FTP" designation is critical for electrical performance: * **S (Screened):** An outer braid shield protects against low-frequency electromagnetic interference (EMI). * **FTP (Foiled Twisted Pair):** Each pair is wrapped in foil to prevent crosstalk between the internal wires, ensuring signal integrity over longer distances. #### C. PUR (Polyurethane) Jacket Unlike standard PVC cables, the PUR jacket is electronically significant because it prevents degradation in environments with high oil, chemical, or mechanical stress, which could otherwise lead to short circuits or signal leakage. --- ### 3. Pinout Mapping (Typical) Since this is a D-Coded 4-pole to RJ45 cable, the wiring follows a specific cross-over or straight-through pattern for Ethernet: | M12 Pin | Signal | RJ45 Pin | | :--- | :--- | :--- | | 1 | TD+ (Transmit +) | 1 | | 2 | RD+ (Receive +) | 3 | | 3 | TD- (Transmit -) | 2 | | 4 | RD- (Receive -) | 6 | --- ### 4. Common Applications * **Industrial Automation:** Connecting PLCs (Programmable Logic Controllers) to switches. * **Robotics:** Used in drag chains due to the flexible PUR jacket. * **Vision Systems:** Transferring data from industrial cameras to processing units. ---
