The **L2CE-12-R/Q** is a specific variant of an industrial connector, typically associated with the **L-Series** circular connectors often manufactured by brands like **LEMO** or equivalent high-precision manufacturers. These parts are designed for high-reliability applications including medical, aerospace, and test instrumentation. ### 1. Component Overview This component is a circular push-pull connector designed for secure, vibration-resistant connections in compact environments. | Feature | Specification | | :--- | :--- | | **Series** | L-Series (Circular) | | **Contact Type** | Solder or Crimp (Depending on suffix) | | **Shell Material** | Chrome-plated brass or Anodized Aluminum | | **Contact Gender** | Male/Female (Defined by R/Q suffix) | | **Ingress Protection** | Often IP50 or IP68 (when mated) | --- ### 2. Breakdown of the Model Code While naming conventions can vary slightly by manufacturer, the code generally follows this logic: * **L2:** Refers to the shell size (Size 2). This dictates the outer diameter and the number of contacts that can fit inside. * **CE:** Indicates the insulator configuration. "C" often stands for a specific contact arrangement (e.g., Coaxial or Mixed contacts), and "E" may denote the environmental sealing level. * **12:** The number of electrical pins/poles. This unit has **12 contacts**. * **R / Q:** These are keying and gender identifiers: * **R:** Usually denotes a fixed receptacle (socket) with specific keying to prevent accidental cross-mating. * **Q:** Often denotes a straight plug or a specific insert type (like a female contact in a male shell). --- ### 3. Electrical Characteristics These connectors are engineered for low signal loss and high durability. * **Rated Current:** Typically between 2A to 7A per contact (depending on wire gauge). * **Test Voltage:** Usually rated for 800V - 1.5kV DC. * **Contact Resistance:** < 5 mΩ (milliohms). * **Durability:** Rated for > 5,000 mating cycles. --- ### 4. Common Applications Due to its robust 12-pin configuration and small footprint, it is used in: 1. **Medical Imaging:** Connecting hand-held probes to main consoles. 2. **Audio/Video:** Professional microphone or camera control links. 3. **Industrial Sensors:** Multi-channel data acquisition systems. 4. **Robotics:** Control signals for robotic arms requiring high-density cabling. --- ### 5. Technical Assembly Tip When working with the **L2CE-12-R/Q**, ensure the use of the correct **Collet** (the internal sleeve that grips the cable). If the cable diameter does not match the collet size, the IP rating will be compromised, and the cable may pull out under tension.
