Based on the part number **47NLDY-YR-R**, this component is a high-performance **LED Indicator / Industrial Pilot Light** manufactured by **IDEC**. It belongs to the **CW series** or similar industrial signaling lines. --- ### 1. Component Specifications This part is designed for industrial control panels, providing visual feedback for machine states. | Feature | Specification | | :--- | :--- | | **Series** | IDEC CW / Miniature Industrial Series | | **Component Type** | LED Pilot Light (Indicator) | | **Mounting Diameter** | 22mm (Standard industrial cutout) | | **Lens Shape** | Round / Dome | | **Color Code (YR)** | Yellow / Amber | | **Input Voltage** | Typically 24V AC/DC (standard for this series) | | **Termination** | Finger-safe screw terminals | --- ### 2. Part Number Breakdown The suffixing and prefixing identify specific physical and electrical attributes: * **47**: Often refers to the internal illumination module or specific bezel style. * **NL**: Indicates a "Neon-Like" or High-Brightness LED illumination type. * **DY**: Refers to the "Diffused" lens type for better wide-angle visibility. * **YR**: The color code for **Yellow** (Amber). * **R**: Indicates the RoHS compliance or a specific revision of the housing. --- ### 3. Key Electronic Characteristics * **Integrated Resistor:** The unit contains internal circuitry to drop the voltage for the LED, allowing it to be connected directly to 24V power sources without an external resistor. * **Polarity Protection:** Most modern IDEC units include a bridge rectifier, making them non-polar (operates on both AC and DC). * **Low Power Consumption:** Uses significantly less current (approx. 15-20mA) compared to traditional incandescent bulbs. * **Inrush Current Protection:** Designed to handle standard industrial power fluctuations without burning out the LED. --- ### 4. Typical Applications * **Control Panels:** Status indication (e.g., "Standby" or "Warning"). * **Automation:** Feedback for PLC (Programmable Logic Controller) outputs. * **Safety:** Visual signaling in manufacturing environments.
