The **M8R12FCJ-R** is a specific electronic component, typically categorized as a **Circular Connector** or a specialized interface cable assembly, often used in industrial automation and sensor applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The "M8" designation refers to the metric thread size, which is a standard in industrial environments for space-constrained applications. | Feature | Specification | | :--- | :--- | | **Connector Type** | M8 Series | | **Gender** | Female (often indicated by "F") | | **Number of Pins/Poles** | Typically 3, 4, or 8 (specific to the model variant) | | **Coupling Type** | Threaded Nut (Screw-lock) | | **Orientation** | Right-Angle (indicated by the "R" or "CJ" suffix in many catalogs) | | **Shielding** | Often shielded to prevent EMI (Electromagnetic Interference) | --- ### 2. Electrical Characteristics These parts are engineered to handle signal transmission and low-power distribution in harsh environments. * **Rated Voltage:** Usually rated for **30V to 60V AC/DC**, depending on the pin count. * **Rated Current:** Typically **1A to 4A** per contact. * **Contact Resistance:** Low resistance (usually $< 5m\Omega$) to ensure signal integrity. * **Insulation Resistance:** High threshold (usually $> 100M\Omega$) to prevent leakage between pins. --- ### 3. Material and Mechanical Design The construction of the M8R12FCJ-R focuses on durability and environmental protection. * **Housing Material:** Often made of Nickel-plated brass or high-performance TPU/PA. * **Contact Plating:** Gold-plated copper alloy for superior conductivity and corrosion resistance. * **IP Rating:** Generally **IP67 or IP68**, meaning it is dust-tight and protected against immersion in water. * **Operating Temperature:** Rated for industrial ranges, typically **-25°C to +85°C**. --- ### 4. Typical Applications The M8 series is a staple in "Factory 4.0" and robotics due to its compact size. 1. **Sensors:** Connecting proximity switches, photoelectric sensors, and ultrasonic transducers. 2. **Actuators:** Driving small solenoid valves or motors. 3. **Data Transmission:** Used in fieldbus systems where space is at a premium. 4. **Robotics:** Used in end-of-arm tooling where weight and size must be minimized. --- ### 5. Part Number Breakdown (Generalized) While manufacturers vary slightly, the nomenclature usually follows this logic: * **M8:** Thread size/Standard. * **R:** Right-angle orientation (for tight spaces). * **12:** Often refers to the cable length (e.g., 1.2 meters) or a specific series code. * **F:** Female connector. * **CJ:** Connector Jacket or specific molding type.
