Based on the part number **M8YV-C44-R/Q**, this component belongs to the **M8 Series** of industrial circular connectors, typically used for sensor and actuator connectivity in automation environments. Below is a detailed breakdown of the electronic and mechanical specifications for this specific configuration. --- ### 1. Technical Specifications The "M8" designation refers to the 8mm metric locking thread. This specific variant is often a 4-pole (4-pin) connector. | Feature | Specification | | :--- | :--- | | **Connector Type** | M8 Circular Connector | | **Gender** | Male (Plug) or Female (Socket) - Depending on manufacturer suffix | | **Number of Poles** | 4-Pin | | **Current Rating** | 3A to 4A (Standard for M8) | | **Voltage Rating** | 30V AC / 60V DC | | **Contact Resistance** | ≤ 5 mΩ | | **Insulation Resistance** | ≥ 100 MΩ | | **IP Rating** | IP67 (Dust tight and water immersion) | --- ### 2. Part Number Breakdown While naming conventions can vary slightly between manufacturers (like OMRON, Phoenix Contact, or TE), the code generally follows this logic: * **M8**: Indicates the 8mm thread diameter. * **YV**: Often denotes the cable material (usually **PVC** - Polyvinyl Chloride) or a specific "Y-type" distribution if applicable. * **C44**: * **4**: 4-wire/4-pin configuration. * **4**: Length indicator (often 0.4m or 4m depending on the series). * **R/Q**: * **R**: Robot-grade cable (High flexibility/torsion resistant). * **Q**: Quick-lock or specific orientation/shielding feature. --- ### 3. Internal Wiring (Standard Color Code) For a 4-pin M8 connector, the electronic signals are typically assigned according to the **IEC 61076-2-104** standard: | Pin Number | Wire Color | Typical Function | | :--- | :--- | :--- | | 1 | Brown | Positive (+) Power Supply | | 2 | White | Secondary Signal / NC / Analog | | 3 | Blue | Negative (-) Power Supply | | 4 | Black | Primary Signal / Digital Out (PNP/NPN) | --- ### 4. Application Areas * **Sensors:** Inductive, capacitive, and photoelectric sensors. * **Actuators:** Small solenoid valves and motor feedback. * **Robotics:** The "R" rating suggests it is designed for use in cable tracks or robotic arms where repetitive bending occurs. * **Factory Automation:** Small-footprint IO-Link devices. ---
