The **C165G-P16-R** is a specific electronic component typically categorized as a **Circular Connector** or a specialized **Cable Assembly/Connector system**. Based on the part numbering convention (often associated with brands like Amphenol or specific industrial connector manufacturers), it is designed for high-reliability signal or power transmission in industrial environments. --- ### 1. Key Technical Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | Circular Industrial Connector | | **Number of Positions** | 16 Pins (as indicated by "P16") | | **Contact Gender** | Male (Plug) or Female (Receptacle) depending on series suffix | | **Mounting Type** | Panel Mount or Cable Mount | | **Termination Style** | Solder or Crimp contacts | | **Housing Material** | High-grade Polymer or Metal Alloy | | **Ingress Protection** | Typically IP65 or IP67 (Dust and Water resistant) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's build: * **C16**: Refers to the series (Commonly the Amphenol Eco-Mate or similar C16 series). * **5G**: Indicates the shell size and specific housing configuration (e.g., locking mechanism). * **P16**: Specifies the contact arrangement (16 active pins). * **R**: Generally stands for **RoHS Compliant** or refers to a **Right-Angle** / **Rear-Mount** orientation. --- ### 3. Physical Components The assembly usually consists of the following electronic and mechanical parts: 1. **Inserts:** The internal block that holds the 16 pins in place, made of insulating material to prevent short circuits. 2. **Contacts:** Copper alloy pins (often gold or silver plated) that conduct the electrical signal. 3. **Coupling Ring:** A threaded or bayonet-style nut used to lock the connector to its mate, ensuring it doesn't vibrate loose. 4. **Strain Relief:** A backshell or grommet that protects the wires from being pulled out of the internal terminals. 5. **Sealing Gasket:** A rubber O-ring that provides the environmental seal (IP rating). --- ### 4. Common Applications Due to its ruggedized nature and high pin density, this part is found in: * **Industrial Automation:** Control signals for robotic arms. * **Machine Tools:** Connecting sensors and actuators to a PLC (Programmable Logic Controller). * **Medical Equipment:** High-density signal cables for diagnostic imaging. * **Energy Sector:** Power monitoring and control interfaces. ---
