The part number **M8YV-F4W4W-R/BL** typically refers to a specialized **M8 Circular Connector Cable Assembly**, commonly used in industrial automation, sensor technology, and robotics. Based on the nomenclature, this is an industrial-grade interface designed for rugged environments. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Component Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | M8 (8mm Threaded) | | **Gender/Orientation** | Field-wireable or Molded (likely Female to Male/Open) | | **Pin Configuration** | 4-Pin (Standard for Sensors/Actuators) | | **Coding** | A-Coded (Standard DC signal/power) | | **Voltage Rating** | 30V AC / 60V DC (Typical) | | **Current Rating** | 3A - 4A per contact | | **Cable Jacket** | PUR (Polyurethane) or PVC (Blue/Black variant) | | **Ingress Protection** | IP67 / IP68 (Dust tight, waterproof) | --- ### 2. Electronic Characteristics * **Signal Integrity:** The 4-pin configuration is optimized for carrying DC power and digital/analog signals from sensors (e.g., proximity sensors, photoelectric eyes). * **Color Coding (`/BL`):** The suffix `/BL` often denotes a **Blue** jacket or specific wiring color code compliant with **NAMUR** standards (intrinsically safe environments) or simply a color-coded identifier for easier cable management in dense control cabinets. * **Shielding:** Depending on the specific sub-variant, these cables often feature foil or braided shielding to prevent Electromagnetic Interference (EMI) in high-voltage industrial environments. --- ### 3. Pinout Diagram (Standard A-Coding) Most M8 4-pin connectors follow this standard electronic pinout: | Pin Number | Wire Color | Typical Function | | :--- | :--- | :--- | | **1** | Brown | +VDC (Power) | | **2** | White | Digital Output 2 / NC | | **3** | Blue | -VDC (Ground) | | **4** | Black | Digital Output 1 (Signal) | --- ### 4. Common Applications 1. **Factory Automation:** Connecting inductive or capacitive proximity sensors to a PLC (Programmable Logic Controller). 2. **Robotics:** End-of-arm tooling where space is limited and a small M8 form factor is required. 3. **IO-Link Devices:** Standard 4-pin M8 cables are the primary interface for IO-Link communication modules.
