The **Y-CONC-R426M-RJ2S-2000-A** is a specialized industrial networking cable assembly, typically produced by manufacturers like **Yamaichi Electronics**. It is designed for high-reliability Ethernet connectivity in harsh environments. ### 1. Part Number Breakdown & Specifications The nomenclature of this part typically refers to the following configuration: | Component Segment | Description | Detail | | :--- | :--- | :--- | | **Y-CON** | Series Name | Yamaichi's industrial RJ45 series | | **R426M** | Connector Type | Industrial Grade RJ45 (usually IP20 or IP67 rated) | | **RJ2S** | Plug Configuration | RJ45 shielded 2-pair or 4-pair connector | | **2000** | Cable Length | 2000mm (2.0 Meters) | | **A** | Revision/Coding | Specific wiring standard or version | --- ### 2. Key Technical Features #### A. Physical Construction * **Shielding:** The "S" in the suffix often denotes a shielded construction (S/FTP or SF/UTP), providing protection against Electromagnetic Interference (EMI) common in factory floors. * **Strain Relief:** Features an over-molded boot or a metal locking mechanism to prevent mechanical stress on the wire terminations. * **Gold Plating:** The internal pins are usually plated with 50μ" of gold to ensure long-term conductivity and prevent oxidation. #### B. Electrical Performance * **Transmission Speed:** Generally supports **Cat 5e** or **Cat 6** standards, allowing for data rates up to 1 Gbps. * **Contact Resistance:** Typically rated < 20 mΩ. * **Voltage Rating:** Standard 125V AC/DC for signal integrity. #### C. Industrial Durability * **Vibration Resistance:** Designed to withstand the constant movement of robotic arms or CNC machinery. * **Mating Cycles:** Rated for > 750 insertion cycles. * **Temperature Range:** Often rated for operation between **-20°C to +80°C**. --- ### 3. Application Use-Cases This cable is primarily found in the following sectors: 1. **Industrial Ethernet:** Connecting PLCs (Programmable Logic Controllers) to HMIs (Human Machine Interfaces). 2. **Machine Vision:** High-speed data transfer for industrial cameras. 3. **Robotics:** Used in cable tracks where flexibility and shielding are mandatory. --- ### 4.
