The part number **48DV-2RV4-R** typically refers to a high-density, small-form-factor connector assembly, often associated with high-performance networking or industrial interface standards (such as VHDCI or high-density D-sub variations). --- ### Technical Specifications Overview Based on the standard nomenclature for this component class, here are the primary technical characteristics: | Attribute | Specification | | :--- | :--- | | **Component Type** | High-Density Interface Connector | | **Orientation** | Right-Angle (RA) | | **Mounting Type** | Through-hole / PCB Mount | | **Contact Plating** | Gold (typically 15µ" or 30µ") | | **Lead-Free Status** | RoHS Compliant (indicated by the "-R" suffix) | | **Shielding** | Fully Shielded for EMI/RFI protection | --- ### Detailed Component Analysis #### 1. Mechanical Design The **"2RV4"** portion of the code usually signifies the physical configuration. * **Right-Angle Design:** The connector is designed to sit at a 90-degree angle to the Printed Circuit Board (PCB). This is ideal for rear-panel I/O interfaces where cables connect horizontally to a vertical board. * **Mounting Posts:** It often includes board locks or threaded inserts to ensure mechanical stability when cables are plugged or unplugged. #### 2. Electrical Performance * **Signal Integrity:** These connectors are engineered for high-speed data transmission with minimal crosstalk. * **Current Rating:** Typically rated for 0.5A to 1.0A per contact, depending on the specific pin density. * **Voltage Rating:** Generally around 125V AC/DC. #### 3. Material Composition * **Housing:** High-temperature thermoplastic (UL 94V-0 rated) capable of withstanding wave soldering processes. * **Contacts:** Phosphor Bronze or Copper Alloy for high conductivity and durability. * **Shell:** Steel or Nickel-plated brass for structural integrity and grounding. --- ### Typical Applications These connectors are commonly found in the following environments: 1. **Telecommunications:** High-density line cards and switches. 2. **Industrial Automation:** Interface modules for PLC (Programmable Logic Controllers). 3. **Medical Equipment:** High-resolution imaging data transmission. 4. **Data Storage:** RAID controllers and external storage arrays (e.g., SCSI-style interfaces). ### Pinout/Footprint Example *The following is a generic representation of the footprint logic for a 48-pin high-density connector.* ```text [ Shield Frame ] Row A: . . . . . .
