The **W2SP-14B-R2/UL** is a specialized high-density electrical connector, primarily utilized in industrial automation, telecommunications, and power distribution systems. It is part of a series often associated with reliable board-to-board or cable-to-board interfacing. --- ### ## Technical Specifications Below are the primary electronic and physical characteristics of the W2SP-14B-R2/UL: | Characteristic | Specification Detail | | :--- | :--- | | **Number of Pins** | 14 Pins | | **Configuration** | Dual Row (usually 2x7 layout) | | **Mounting Type** | Through-hole or SMT (depending on specific R2 variant) | | **Pitch** | Typically 2.0mm or 2.54mm | | **Safety Rating** | UL Recognized (UL94V-0 Flame Retardant) | | **Material** | High-temperature thermoplastic / Phosphor Bronze contacts | | **Plating** | Gold or Tin-Lead over Nickel | --- ### ## Key Electronic Components & Features #### 1. Contact Resistance The internal metal pins (Phosphor Bronze) are engineered for low contact resistance (typically $<20m\Omega$). This ensures minimal voltage drop across the connection, which is critical for signal integrity in logic circuits. #### 2. Dielectric Withstanding Voltage The housing material is designed to prevent electrical arcing between adjacent pins. It generally supports a breakdown voltage of **500V AC/minute** or higher, ensuring safety in power-sensitive applications. #### 3. Insulation Resistance The W2SP series uses high-grade insulators that provide a resistance of over **1000M\Omega**, preventing leakage current between signals, which is vital for high-frequency or high-impedance circuits. #### 4. Current Capacity Each pin is typically rated to handle between **1A to 3A** of current. If the application requires higher amperage, multiple pins are often grouped together. --- ### ## Common Applications * **PLC Modules:** Used for internal data routing within Programmable Logic Controllers. * **Power Supplies:** Acts as a bridge between the transformer secondary and the main PCB. * **Networking Gear:** Used for mezzanine card connections in routers and switches. ---
