The **FP2-S082-R** is a specific electronic component, typically categorized as a **D-Sub high-density connector** or a specialized **PCB mounting socket**, often associated with the Panasonic FP2 series PLC (Programmable Logic Controller) expansion or similar industrial automation hardware. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Technical Specifications The FP2-S082-R is designed for high-density signal transmission and robust electrical connectivity. | Feature | Description | | :--- | :--- | | **Component Type** | D-Sub Connector / Interface Terminal | | **Pin Configuration** | 82-Pin (High Density) | | **Mounting Type** | Through-hole / PCB Mount | | **Orientation** | Right Angle (indicated by the "-R" suffix) | | **Application** | Industrial Control, PLC I/O Expansion, Data Interfacing | | **Contact Plating** | Gold over Nickel (standard for reliability) | --- ### 2. Key Electronic Characteristics #### A. Signal Integrity Due to the high pin density (82 pins), the component is engineered to minimize cross-talk and electromagnetic interference (EMI). It is frequently used to bridge a PLC CPU or I/O module to an external terminal block. #### B. Contact Resistance * **Maximum Resistance:** Usually rated at ≤ 15mΩ. * **Purpose:** Low resistance ensures that low-voltage logic signals (5V/24V DC) are transmitted without significant voltage drops. #### C. Insulation and Dielectric Strength * **Insulation Resistance:** Typically ≥ 1000MΩ at 500V DC. * **Dielectric Withstanding Voltage:** Designed to withstand 500V - 1000V AC for one minute to prevent arcing between adjacent pins. --- ### 3. Physical & Mechanical Parts 1. **Housing:** Made of Thermoplastic (UL94V-0 rated) to ensure heat resistance during soldering and operation. 2. **Shell:** Steel or Brass with Tin or Nickel plating for grounding and structural shielding. 3. **Contacts:** Copper alloy base for high conductivity. 4. **Right-Angle Pins:** The "R" designation means the pins are bent at 90 degrees to allow the connector to sit flush on the edge of a PCB, saving vertical space in industrial enclosures. --- ### 4. Implementation Example (PLC Context) In a Panasonic FP2 PLC system, this part acts as the physical interface between: * The **Internal Logic Circuitry** (Motherboard). * The **External Wiring** (Ribbon cables or Discrete wires via a terminal converter). ```cpp // Example: Conceptual mapping of pins for an 82-pin connector struct FP2_Connector { int input_pins[32]; // Pins 1-32: Digital Inputs int output_pins[32]; // Pins 33-64: Digital Outputs int power_rails[8]; // Pins 65-72: VCC/GND int reserved[10]; // Pins 73-82: Shield/NC }; ``` ---
