The **WJM-14W2-R** is a specific electronic connector component, typically categorized as a **D-Sub Mixed Contact Connector**. These connectors are designed to combine standard signal pins with specialized "Coaxial" or "High Power" cavities within a single housing. Below is a detailed breakdown of its electronic and physical specifications. --- ### 1. General Specifications The part number follows a standard nomenclature for high-density and mixed-layout connectors. | Feature | Description | | :--- | :--- | | **Connector Type** | D-Sub (Mixed Layout) | | **Contact Arrangement** | 14W2 (14 total positions: 12 Signal + 2 Power/Coax) | | **Gender** | Receptacle (Female Socket) | | **Mounting Type** | Through-Hole / Right Angle (indicated by 'R') | | **Shell Material** | Steel (typically Tin or Nickel plated) | --- ### 2. Contact Configuration The "14W2" designation is the most critical part of its electronic design: * **12 Signal Pins:** Standard 5A rated pins for data or low-current signals. * **2 Special Cavities:** These oversized holes are designed to house either: * **High-Power Contacts:** (Up to 20A or 40A depending on the specific insert). * **Coaxial Contacts:** For Radio Frequency (RF) signals requiring shielding. --- ### 3. Electrical Characteristics These values are standard for industrial-grade WJM series connectors. | Parameter | Typical Value | | :--- | :--- | | **Current Rating (Signal)** | 5 Amperes | | **Current Rating (Power)** | 20A to 40A (insert dependent) | | **Dielectric Withstanding Voltage** | 1000V AC at sea level | | **Insulation Resistance** | > 5000 MΩ | | **Contact Resistance** | < 10 mΩ | | **Operating Temperature** | -55°C to +125°C | --- ### 4. Common Applications Due to its ability to carry both power and data, the WJM-14W2-R is frequently used in: * **Telecommunications:** Base stations and switching equipment. * **Industrial Automation:** Connecting PLCs to motors where both control logic and power are needed. * **Medical Electronics:** Imaging equipment requiring high-voltage/high-current paths alongside sensor data. * **Military/Aerospace:** Robust interconnections for ruggedized computers. --- ### 5.
