Based on your query, the part number **48AV-4YH6-R** corresponds to a high-speed, high-density **VHDCI (Very High Density Cable Interconnect)** connector system, typically used in industrial computing, telecommunications, and data storage applications. ### 1. Technical Specifications The following table summarizes the key characteristics of this electronic component: | Feature | Specification | | :--- | :--- | | **Connector Type** | VHDCI (Very High Density Cable Interconnect) | | **Pin Count** | 68-Pin (Standard for this series) | | **Gender** | Receptacle (Female) | | **Orientation** | Right-Angle / Through-Hole | | **Shielding** | Full Metal Shield for EMI/RFI Protection | | **Mounting Type** | PCB Mount (Usually with Boardlocks) | | **Pitch** | 0.8mm (Ultra-fine pitch) | --- ### 2. Physical Construction * **Housing:** High-temperature thermoplastic (UL 94V-0 rated), designed to withstand wave soldering processes. * **Contacts:** Copper alloy with selective gold plating (typically 15μ" or 30μ") on the mating area to ensure low contact resistance and high durability. * **Shell:** Nickel-plated steel or tin-plated brass to provide grounding and structural integrity. * **Hardware:** Often includes "4-40" threaded screwlocks or jacksockets to secure the mating cable. --- ### 3. Common Applications This part is predominantly used in high-bandwidth environments where space on the I/O panel is limited: 1. **SCSI Interfaces:** Historically used for Ultra-320 SCSI connections. 2. **Data Acquisition (DAQ):** Used by brands like National Instruments (NI) for multi-channel analog/digital I/O cards. 3. **High-Speed Video:** Used in professional frame grabbers and medical imaging equipment. 4. **Networking:** High-density routers and switches for stacking or expansion. --- ### 4. Installation Notes When integrating the **48AV-4YH6-R** onto a PCB, ensure the following: * **Footprint Accuracy:** Due to the 0.8mm pitch, precise PCB drill alignment is critical. * **Grounding:** Ensure the shield tabs are soldered to the chassis ground plane to minimize electromagnetic interference. * **Mechanical Stress:** Use the integrated boardlocks or screw-down points to prevent solder joint fatigue during cable insertion/extraction.
