The **2B16-R** typically refers to a specific series of **Wire-to-Board Connectors** or specialized electronic components often used in industrial control systems and power management. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Component Overview The 2B16-R is primarily identified as a high-density connector, often part of a modular interconnect system. It is designed to bridge the gap between a Printed Circuit Board (PCB) and external wiring. ### Key Specifications | Feature | Description | | :--- | :--- | | **Pitch** | Generally 2.0mm or 2.5mm (depending on manufacturer) | | **Pin Count** | 16 Pins (as indicated by the "16" in the part number) | | **Mounting Type** | Through-hole or Surface Mount (SMT) | | **Orientation** | Right-Angle (indicated by the "R") | | **Current Rating** | Usually 1A to 3A per pin | | **Voltage Rating** | 100V to 250V AC/DC | --- ## 2. Technical Features ### A. Right-Angle Design ("-R") The "R" suffix is critical in electronics. It indicates that the connector pins are bent at a **90-degree angle**. * **Space Saving:** Ideal for low-profile enclosures where vertical space is limited. * **Side Entry:** Allows wires to be plugged in from the side of the board rather than the top. ### B. Contact Materials * **Base Metal:** Typically Phosphor Bronze or Brass for high conductivity. * **Plating:** Usually Tin-plated or Gold-flash to prevent oxidation and ensure low contact resistance. ### C. Housing Materials * **Material:** Thermoplastic (e.g., Nylon 66 or LCP). * **Flammability:** Often rated **UL94V-0**, meaning it is self-extinguishing in case of a fire. --- ## 3. Applications The 2B16-R is commonly found in the following sectors: 1. **Industrial Automation:** Used in PLC (Programmable Logic Controller) modules for signal routing. 2. **Consumer Electronics:** Found in internal power distributions for appliances. 3. **Computing:** Used as headers for peripheral connections on motherboards or expansion cards. 4. **Automotive:** Low-current signal transmission for dashboard displays. --- ## 4. Typical Wiring Diagram (16-Pin) While pinouts vary by specific device implementation, a standard 16-pin header follows this physical layout: ```text [ 1 3 5 7 9 11 13 15 ] <-- Top Row [ 2 4 6 8 10 12 14 16 ] <-- Bottom Row (90-degree bend to PCB) ``` ---
