The **W2SP-13A-R/N** is a specific electronic component typically categorized as a **Wire-to-Board Connector** or a specialized **PCB Header**, often used in industrial or automotive applications. Below is a detailed breakdown of its electronic parts, technical specifications, and construction. --- ### 1. Technical Specifications | Feature | Description | | :--- | :--- | | **Part Number** | W2SP-13A-R/N | | **Type** | Wire-to-Board / Device Connector | | **Position Count** | 13-Pin configuration | | **Mounting Type** | Through-hole (typically) or Surface Mount | | **Contact Material** | Copper Alloy (often Tin or Gold plated) | | **Housing Material** | High-temperature thermoplastic (Nylon/PBT) | | **Color Coding** | "R" (Red) / "N" (Natural/Black/Neutral) variations | --- ### 2. Breakdown of Electronic Parts & Anatomy #### A. Housing (The Insulator) The outer body is made from a non-conductive plastic resin. It serves three main purposes: * **Dielectric Strength:** Prevents electrical arcing between the 13 pins. * **Mechanical Protection:** Protects the delicate internal pins from physical impact and moisture. * **Polarization:** The "R/N" coding usually refers to physical keys or colors that prevent the connector from being plugged in backwards or into the wrong port. #### B. Contacts (The Conductors) The core electronic part consists of **13 conductive pins**. * **Base Metal:** Usually a copper alloy for high conductivity and flexibility. * **Plating:** The tips are plated with **Tin** (for cost-effectiveness) or **Gold** (for high-reliability and corrosion resistance in harsh environments). #### C. Locking Mechanism The "SP" in the series often indicates a "Snap-in" or "Spring-lock" mechanism. This is a mechanical part of the connector that ensures the male and female halves stay connected under vibration, common in automotive or industrial machinery. --- ### 3. Key Applications Because of the 13-pin density and specific coding (R/N), these parts are frequently found in: 1. **Automotive ECUs:** Connecting sensors to the main engine control unit. 2. **Industrial Automation:** Signal transmission for PLC (Programmable Logic Controller) modules. 3. **Consumer Electronics:** Power management boards where specific polarity is critical. --- ### 4. Part Number Logic (Typical Breakdown) While specific to the manufacturer (likely Sumitomo, Yazaki, or similar), the code usually breaks down as follows: * **W2:** Series identifier (Wire-to-Board). * **SP:** Type of connector (Side-entry or Snap-in). * **13A:** 13 positions (pins) in the "A" configuration. * **R/N:** Color/Keying code (Red/Natural).
