The part number **M8YV-4W44-R/F** belongs to the **M8 Series** of industrial circular connectors, typically manufactured by companies like **Hirose (HRS)** or specialized industrial sensor cable providers. These connectors are primarily used for sensor/actuator connections in automation. --- ### 1. Technical Specification Breakdown The alphanumeric code describes the physical and electrical characteristics of the connector: | Code Segment | Description | Specific Detail | | :--- | :--- | :--- | | **M8** | Connector Size | Metric 8mm thread diameter (Standard size). | | **YV** | Coupling Type | Often denotes a specialized locking or Y-junction variant. | | **4W** | Wire/Pin Count | 4-Wire (4-Pole) configuration. | | **44** | Contact Mapping | Standard pin-to-pin wiring (Straight through). | | **R/F** | Gender/Form | **R** usually denotes Right-Angle; **F** denotes Female (Socket). | --- ### 2. Electrical Characteristics These parts are designed for low-voltage signal transmission in harsh environments. * **Rated Voltage:** Typically 30V to 60V AC/DC. * **Rated Current:** Usually 3A to 4A per contact. * **Contact Resistance:** < 10 mΩ. * **Insulation Resistance:** > 100 MΩ. * **IP Rating:** Generally **IP67** (dust-tight and protected against water immersion). --- ### 3. Physical Construction * **Housing Material:** Typically TPU (Thermoplastic Polyurethane) or PBT. * **Contact Material:** Brass or Phosphor Bronze with **Gold Plating** to prevent oxidation. * **Coupling Nut:** Nickel-plated brass or stainless steel for corrosion resistance. * **Cable Jacket:** Often PUR (Polyurethane) or PVC, depending on the specific sub-model (R/F versions often use PUR for high-flex applications). --- ### 4. Common Applications These electronic parts are critical components in the following sectors: 1. **Factory Automation:** Connecting Proximity Sensors, Photoelectric Cells, and Limit Switches. 2. **Robotics:** End-of-arm tooling where compact, right-angled (R) connectors save space. 3. **Data Acquisition:** Connecting I/O modules to PLC (Programmable Logic Controller) systems. --- ### 5. Pinout Configuration (Standard 4-Pole) Most M8 4-pin connectors follow this standard industrial wiring: ```text Pin 1: Brown (+) 24V DC Pin 2: White (I/O) Reserved/Signal 2 Pin 3: Blue (-) 0V / Common Pin 4: Black (OUT) Switching Signal 1 ```
