The **LA112B-GX-R1-AS-PF** is a specialized electronic component primarily categorized as an **LED (Light Emitting Diode) Indicator** or an **Optical Sensor Housing**. While the specific internal configurations can vary based on the manufacturer's sub-series (often associated with brands like Kingbright or specialized Taiwanese optoelectronics firms), here is the technical breakdown of its parts and characteristics. --- ### 1. Technical Specifications This component is typically a surface-mount (SMD) or through-hole infrared/visible light assembly. | Feature | Specification | | :--- | :--- | | **Part Type** | Optoelectronic / LED Module | | **Color/Wavelength** | Usually Green (GX suffix often denotes Green) | | **Mounting Type** | R1 (Right Angle) or Standard Vertical | | **RoHS Status** | Lead-Free (PF - Pb Free) | | **Housing Material** | Black Thermoplastic (UL94V-0 Rated) | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a specific engineering nomenclature: * **LA**: Often represents the series code for a specific lamp assembly or indicator style. * **112B**: Refers to the physical dimensions and lens geometry (Square/Rectangular profile). * **GX**: Designates the color and chemical composition of the semiconductor chip (e.g., GaP for Green). * **R1**: Indicates a variation in lead forming, often "Right Angle" for side-view applications. * **AS**: Anti-Static treatment or specific assembly style. * **PF**: **Pb-Free** (Lead-Free), indicating compliance with environmental regulations. --- ### 3. Internal Component Structure The device consists of three primary electronic sub-parts: 1. **Semiconductor Die (The Chip):** The heart of the part, typically made of Gallium Phosphide (GaP) or Indium Gallium Nitride (InGaN), which converts electrical energy into light. 2. **Lead Frame:** The metal structure (usually tin-plated copper) that provides mechanical support and electrical conductivity from the PCB to the chip. 3. **Encapsulant/Lens:** An epoxy resin that protects the die. The "B" in the part number often indicates a specific lens tint or diffusion level to ensure uniform light output. --- ### 4. Applications These parts are commonly found in: * **Network Equipment:** Link/Activity status lights on routers and switches. * **Industrial Panels:** Status indicators for PLC (Programmable Logic Controllers). * **Consumer Electronics:** Power-on indicators for appliances. ---
