The part number **Y-CONC-R40CU-RJ2M-2000-C** refers to a high-speed data transmission cable assembly, typically used in industrial automation, machine vision, or specialized telecommunications. Below is a breakdown of the electronic components and technical specifications associated with this type of assembly. ### 1. Component Breakdown | Segment | Component Type | Description | | :--- | :--- | :--- | | **Connector A** | Round 40-Pin (R40) | A high-density circular connector, often used for PLC (Programmable Logic Controller) or I/O module interfaces. | | **Connector B** | RJ45 (RJ) | Standard 8P8C modular connector, likely used for Ethernet or serial communication protocols. | | **Cable Core** | Copper (CU) | Multi-core copper wiring designed for low-impedance and reliable signal integrity. | | **Length** | 2000mm | The assembly is 2 meters (approx. 6.5 feet) in length. | | **Shielding** | C (Shielded) | Indicates the cable features EMI/RFI shielding (likely Braided or Foil) to prevent signal interference. | --- ### 2. Technical Specifications This cable is engineered to bridge high-density control equipment with standard networking or terminal equipment. #### Electrical Characteristics * **Conductor Material:** High-purity Copper. * **Insulation:** Polyethylene (PE) or PVC, depending on the environmental rating. * **Shielding:** STP (Shielded Twisted Pair) configuration to minimize crosstalk and external noise. * **Pin Mapping:** Typically follows a proprietary mapping from the 40-pin circular interface to the 8 pins of the RJ45 (often used for splitting signals or specific bus protocols like CC-Link or Profinet). #### Mechanical & Environmental * **Jacket Material:** Industrial-grade PVC or PUR (Polyurethane) for oil and abrasion resistance. * **Operating Temperature:** Generally rated for -20°C to +75°C. * **Connector Housing:** Metal or high-impact plastic with locking mechanisms (screw-on or bayonet for the R40 side). --- ### 3. Application Use Cases This specific part is most commonly found in the following electronic environments: 1. **Industrial Robotics:** Connecting robotic controllers to local area networks or vision sensors. 2. **PLC Interfacing:** Transitioning from a high-density I/O card (40-pin) to a standard diagnostic port or network switch. 3. **Automated Testing:** Used in test benches where high-density signal routing needs to be converted to standard RJ45 patch panels. --- ### 4. Wiring Diagram Example (Generic) While the exact pinout is manufacturer-specific (likely Yamaichi or a similar industrial brand), the logical structure follows this pattern: ```text [ 40-Pin Circular ] <---- (Shielded Multi-Core) ----> [ RJ45 Plug ] Pins 1-8 --------------------------> Pins 1-8 Pins 9-40 --------------------------> (NC or Grounded) ```
