The **CA3N-R** is a specific type of industrial connector, typically classified as a **Circular Connector** or a **Power/Signal Connector** often used in automotive, marine, or heavy equipment industries. It is frequently associated with brands like **Bulgin** or **Amphenol** (specifically within the CA series). --- ### 1. Technical Specifications The "CA" series generally refers to high-reliability connectors designed for harsh environments. Below are the typical electronic and mechanical characteristics for a CA3N-R variant: | Feature | Specification | | :--- | :--- | | **Connector Type** | Circular Bayonet or Screw-on | | **Contact Arrangement** | 3-Pole (typically 3 contacts) | | **Rated Voltage** | 250V - 400V AC/DC | | **Rated Current** | 10A to 16A (depending on wire gauge) | | **Protection Class** | IP67 / IP68 (Waterproof & Dustproof) | | **Mounting Type** | Panel Mount or Cable Mount | | **Termination** | Solder or Screw terminals | --- ### 2. Key Components The CA3N-R consists of several internal electronic and structural parts: 1. **Contacts (Pins/Sockets):** Usually made of gold or silver-plated brass to ensure high conductivity and resistance to oxidation. 2. **Inserts:** Made of high-grade thermoplastics (like Polyamide) to provide electrical insulation between the pins and the outer shell. 3. **Coupling Ring:** The mechanical "R" designation often refers to a **Right-angle** orientation or a **Retaining** ring that locks the connection in place to prevent accidental disconnection due to vibration. 4. **Seals/O-Rings:** High-performance rubber gaskets that ensure the "R" (Ruggedized) rating and environmental sealing. --- ### 3. Application Use Cases Due to its robust design, the CA3N-R is found in the following electronic systems: * **Industrial Automation:** Connecting sensors and actuators to control boxes. * **Marine Electronics:** Used in onboard power systems where salt spray and moisture are present. * **Medical Equipment:** For secure, easy-to-clean power connections. * **Lighting Systems:** Frequently used in outdoor LED stage lighting and architectural power distribution. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, the code usually breaks down as follows: * **CA:** Circular Series / Connector Assembly. * **3:** Number of active contacts (3-pole). * **N:** Neutral/Standard coding or specific shell size. * **R:** Right-angle backshell or Reverse gender/configuration.
