The term **CN-R** typically refers to a standardized series of **circular connectors** or **ribbon cable connectors** used in electronic assemblies. In many industrial contexts (especially within Asian electronics manufacturing like Panasonic or Misumi), it designates high-reliability interface components. --- ### 1. Common Types of CN-R Components Depending on the specific manufacturer, the "CN-R" prefix usually falls into one of these two categories: | Part Type | Description | Common Use Case | | :--- | :--- | :--- | | **Ribbon Connectors** | Rectangular connectors designed for flat ribbon cables. | Internal PC wiring, PLC interfaces. | | **Circular Connectors** | Round, metal or plastic shells with threaded or bayonet locking. | Industrial sensors, motor power, aviation. | | **Right-Angle (R)** | The "R" often signifies a **Right-Angle** PCB mount orientation. | Compact enclosures where space is limited. | --- ### 2. Key Technical Specifications When dealing with CN-R series electronics, engineers look at these four primary metrics: 1. **Pin Count:** Usually ranges from 2 pins (power) up to 50+ pins (data signal). 2. **Pitch:** The distance between the center of one pin and the next (e.g., 1.27mm, 2.0mm, or 2.54mm). 3. **Current Rating:** Typically 1A to 5A for signal types, and higher for power-specific R-series. 4. **Termination Style:** * **Through-hole (THT):** Pins go through the PCB. * **Surface Mount (SMT):** Soldered directly onto the board surface. * **IDC:** Insulation-displacement contact for quick ribbon cable attachment. --- ### 3. Application Examples * **PLC Modules:** CN-R connectors are frequently used as the I/O interface between a Programmable Logic Controller and external sensors. * **Medical Equipment:** Used in diagnostic machines for secure, vibration-resistant data transmission. * **Robotics:** The "R" (Right-Angle) version is critical for joints where cables must exit parallel to the circuit board to avoid strain. --- ### 4. Typical Material Composition ```yaml Components: Contacts: Phosphor Bronze or Brass Plating: Gold (for high conductivity) or Tin (cost-effective) Insulator: PBT Plastic (UL94V-0 rated for fire safety) Shell: Nickel-plated Zinc alloy (for Circular R-series) ```
