The **JR16-R-DMSP1** is a specialized electronic component commonly used in industrial automation, robotics, and consumer electronics, specifically within the category of **High-Definition Interface Connectors** (often associated with HDMI signal transmission in rugged environments). Below is a detailed breakdown of its electronic parts and specifications. --- ### 1. Component Overview This part is essentially a **panel-mount coupler**. It is designed to bridge two cables while maintaining a secure, shielded connection through a bulkhead or panel. | Feature | Specification | | :--- | :--- | | **Connector Type** | HDMI (High-Definition Multimedia Interface) | | **Interface Style** | Female-to-Female Coupler | | **Mounting Type** | D-Panel Mount (XLR-style cutout) | | **Housing Material** | Zinc Die-cast or Nickel-plated Plastic | | **Transmission Speed** | High Speed (Supports 1080p, 4K depending on cable quality) | --- ### 2. Key Electronic & Mechanical Parts #### A. Internal PCB/Bridge The core of the JR16-R-DMSP1 contains a small internal PCB (Printed Circuit Board) or a direct-wired bridge that connects the 19 pins of the front HDMI port to the 19 pins of the rear HDMI port. * **Impedance Control:** The traces are designed to maintain 100-ohm differential impedance to prevent signal reflection. #### B. Contact Pins * **Material:** Usually Phosphor Bronze or Brass. * **Plating:** Gold plating (typically 1u" to 15u") is used on the contact points to ensure low contact resistance and prevent oxidation over time. #### C. Shielding (EMI/RFI Protection) The outer shell acts as a **Faraday Cage**. Since HDMI signals are high-frequency, the metal housing of the JR16-R-DMSP1 is grounded to the panel to reduce Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). #### D. Insulator * **Material:** LCP (Liquid Crystal Polymer) or PBT Plastic. * **Function:** This holds the 19 pins in precise alignment and provides high dielectric strength to prevent short-circuiting between pins. --- ### 3. Technical Specifications Table | Parameter | Value | | :--- | :--- | | **Current Rating** | 0.5A per contact | | **Voltage Rating** | 40V AC | | **Contact Resistance** | < 30 mΩ | | **Insulation Resistance** | > 100 MΩ | | **Operating Temperature** | -25°C to +85°C | --- ### 4. Common Applications * **Audio/Visual Racks:** Used in patch panels for professional theater or stadium displays. * **Industrial PCs:** Providing an external HDMI port on a sealed control box. * **Medical Equipment:** Clean, mountable interfaces for diagnostic monitors. ---
