The **Y-CONC-R422M-RJ2M-2000-C** is a specialized industrial circular-to-RJ45 connection cable, typically used in high-speed data transmission environments such as industrial Ethernet, factory automation, and sensor networking. Below is the detailed breakdown of its electronic and mechanical parts. --- ### 1. General Specifications This part number describes a cable assembly with specific connectors and lengths. | Feature | Specification | | :--- | :--- | | **Connector A** | M12 Circular Connector (4-pin, D-coded) | | **Connector B** | RJ45 Standard Ethernet Connector | | **Cable Length** | 2000mm (2 Meters) | | **Data Rate** | Up to 100 Mbps (Fast Ethernet) | | **Shielding** | S/FTP or SF/UTP (Double shielded) | --- ### 2. Breakdown of Electronic Parts #### A. The M12 Connector (R422M) The **M12 D-coded** connector is the industry standard for industrial Ethernet. * **Pins:** 4 Pins. * **Coding:** D-Code (specifically for Ethernet/Data). * **Housing:** Usually nickel-plated brass or stainless steel to ensure electromagnetic compatibility (EMC). * **Protection:** Rated for **IP67/IP68**, making it dust-tight and waterproof. #### B. The RJ45 Connector (RJ2M) The standard Ethernet interface used for connecting to switches, PLCs, or PCs. * **Contacts:** Gold-plated phosphor bronze to prevent oxidation and ensure low contact resistance. * **Housing:** Often features a "boot" or strain relief to prevent the clip from snapping in harsh environments. #### C. The Cable Structure The "2000" refers to the 2-meter length, but the internal construction is critical for signal integrity: * **Conductors:** Usually 22 AWG or 24 AWG stranded tinned copper. * **Shielding:** Integrated foil and copper braid shielding to protect data from **EMI (Electromagnetic Interference)** caused by industrial motors or high-voltage lines. * **Jacket Material:** Typically **PUR (Polyurethane)** or **LSZH (Low Smoke Zero Halogen)**, providing resistance to oils, chemicals, and abrasion. --- ### 3. Pinout Configuration (M12 to RJ45) For D-coded industrial Ethernet, the wiring typically follows this mapping: | M12 Pin (D-Coded) | Signal | RJ45 Pin | | :--- | :--- | :--- | | 1 | Transmit + (TD+) | 1 (White/Orange) | | 2 | Receive + (RD+) | 3 (White/Green) | | 3 | Transmit - (TD-) | 2 (Orange) | | 4 | Receive - (RD-) | 6 (Green) | --- ### 4. Typical Applications * **Industrial Automation:** Connecting PLCs to sensors or HMIs. * **Vision Systems:** Connecting industrial cameras to a local network. * **Robotics:** Data transmission in high-flex environments where standard RJ45 cables would fail.
