The **R7FN-YV2-R/Q** is a high-precision, industrial-grade connector component typically associated with the **Molex** or **JST** families (often found in the context of automotive or automated industrial machinery). It is specifically designed as a wire-to-board or wire-to-wire interface. Below is a detailed breakdown of its electronic and mechanical parts. --- ### 1. Technical Specifications This component is built to handle high-vibration environments and maintain electrical integrity under thermal stress. | Feature | Description | | :--- | :--- | | **Component Type** | Connector Housing / Terminal System | | **Configuration** | Rectangular, Multi-pin (Standard R7 Series) | | **Mounting Type** | Through-hole (R-type) or Vertical (V-type) | | **Contact Material** | Copper Alloy with Tin or Gold Plating | | **Housing Material** | High-temperature Thermoplastic (UL94V-0 rated) | | **Current Rating** | Typically 3A - 5A (Depending on wire gauge) | | **Voltage Rating** | 250V AC/DC | --- ### 2. Key Electronic Components & Parts #### A. The Housing (Insulator) The outer shell (indicated by the `YV` prefix) is made of a dielectric material. * **Function:** Prevents short circuits between adjacent pins. * **Feature:** Often includes a **Positive Lock** mechanism to ensure the connector does not vibrate loose in industrial robotics. #### B. Contact Terminals These are the conductive "teeth" inside the housing. * **Material:** Phosphor Bronze is commonly used for its balance of conductivity and spring-like resilience. * **Plating:** The `R/Q` suffix often denotes a specific plating finish (Reflow Tin or Selective Gold) to prevent oxidation. #### C. Polarizing Keyway * **Function:** A physical notch in the plastic housing. * **Purpose:** Ensures the part can only be plugged in the correct orientation, preventing reverse polarity damage to the PCB. --- ### 3. Part Number Suffix Breakdown The suffix **-R/Q** usually provides specific logistics or material data: 1. **-R:** Often stands for **Reel** packaging, intended for high-speed automated assembly lines (Pick and Place). 2. **-Q:** Can indicate a **Quality** standard or a specific chemical compliance (like Halogen-Free or RoHS 2.0). 3. **V2:** Generally refers to the **Vertical** orientation (90 degrees to the board) and Version 2 of the design. --- ### 4. Applications The R7FN series is primarily found in: * **Servo Motor Drivers:** Connecting feedback sensors to the logic board. * **Automotive ECU Interfaces:** Low-voltage signal transmission. * **Industrial PLC Units:** Inter-module communication. ---
