The **LPA-14P2W-R** is a specific electronic component typically categorized as a **LED Panel Indicator** or a **Light Pipe Assembly**. These components are designed to transmit light from an onboard LED (usually SMD) to a front panel interface, providing visual status indicators for electronic equipment. --- ### 1. Technical Specifications Below are the general technical parameters associated with this type of light pipe assembly: | Feature | Specification | | :--- | :--- | | **Part Series** | LPA (Light Pipe Array/Assembly) | | **Positions** | 14-Port / 14-Position | | **Configuration** | 2-Wide (usually 2 rows of 7 or similar grid) | | **Mounting Type** | Right Angle / Panel Mount | | **Material** | Polycarbonate (Clear) | | **Flammability Rating** | UL 94-V0 | --- ### 2. Key Electronic Functions The LPA-14P2W-R serves several critical roles in an electronic system: * **Light Transmission:** It uses total internal reflection (TIR) to guide light from a PCB-mounted LED to the exterior of an enclosure with minimal light loss. * **Optical Isolation:** The structure is designed to prevent "light bleed" between the 14 different ports, ensuring that an active LED does not illuminate adjacent indicators. * **ESD Protection:** By providing a physical distance between the external environment and the sensitive PCB components, the plastic assembly helps prevent Electrostatic Discharge (ESD) from reaching the internal circuitry. --- ### 3. Physical Structure The "14P2W" designation specifically refers to the layout: * **14P:** 14 individual light channels (Ports). * **2W:** Arranged in 2 rows (2-Wide), meaning a 7x2 matrix. * **-R:** Generally indicates a **Right Angle** orientation, meaning the LEDs sit vertically on the PCB, and the light is turned 90 degrees to face the user. ### 4. Typical Applications 1. **Networking Gear:** Status lights for RJ45 ports on switches and routers. 2. **Industrial Controls:** Power, error, and activity indicators on DIN-rail modules. 3. **Storage Servers:** Drive activity and health monitors in blade servers. --- ### Integration Example When designing a PCB for this part, the footprint must align perfectly with the SMD LEDs. ```markdown PCB Layout Considerations: 1. LED Pitch: Must match the center-to-center distance of the LPA ports. 2. Height Clearance: Ensure no tall components (capacitors/inductors) obstruct the light pipe path. 3. Light Shielding: Use black solder mask or physical barriers if high-intensity LEDs are used. ```
