The part number **225-510-R** generally refers to a specific series of high-performance **D-Sub connectors** or **Card Edge connectors**, most notably associated with manufacturers like **EDAC Inc** or specialized electronic hardware distributors. Below is a detailed breakdown of the technical specifications, features, and applications for this component. --- ### 1. Technical Specifications This part typically belongs to the **Card Edge** connector category, used to connect printed circuit boards (PCBs) to a backplane or another board. | Feature | Specification (Typical) | | :--- | :--- | | **Connector Type** | Card Edge / Edgeboard | | **Number of Positions** | 10 Positions (Single Row/Dual depending on suffix) | | **Pitch** | 0.156" (3.96mm) | | **Contact Gender** | Female | | **Mounting Type** | Through Hole / Right Angle / PC Tail | | **Contact Material** | Copper Alloy | | **Contact Plating** | Gold (R-suffix often indicates RoHS compliance) | | **Current Rating** | 3A to 5A | --- ### 2. Physical Construction The "225" series identifies the physical housing and spacing characteristics: * **Insulator Material:** Usually a UL 94V-0 rated thermoplastic (Polyphenylene Sulfide or Diallyl Phthalate). * **Contact Design:** Features a "Bellows" or "Cantilever" contact style. This ensures consistent pressure on the mating board even after multiple insertion cycles. * **Polarization:** Often includes slots for polarizing keys to ensure the board is inserted correctly. --- ### 3. Key Features * **RoHS Compliant:** The **-R** suffix in modern electronics nomenclature almost universally signifies that the part meets "Restriction of Hazardous Substances" standards (Lead-free). * **Durability:** Designed for high-reliability environments where vibration might occur. * **Versatility:** Can be used for wire-wrap, solder eyelet, or PC tail applications depending on the specific tail length. --- ### 4. Common Applications These connectors are "legacy" but still widely used in specific industrial sectors: 1. **Industrial Controls:** Connecting PLC modules to a main bus. 2. **Classic Computing:** Used in older bus architectures (like ISA slots or early arcade system boards). 3. **Test Equipment:** Providing a pluggable interface for replaceable sensor boards. 4. **Power Supplies:** High-current edge connections for modular power units. --- ### 5. Identification Code Breakdown While codes vary slightly by manufacturer, the 225-510-R usually follows this logic: | Segment | Meaning | | :--- | :--- | | **225** | Series designation (0.156" Pitch Card Edge) | | **510** | Specific configuration (Number of contacts & tail type) | | **-R** | RoHS Compliant / Lead-Free | ---
