The **AP2N-R** is a specific model within the series of industrial-grade pilot lights (indicator lamps), typically manufactured by companies like **IDEC**. These components are essential in control panels to provide visual feedback regarding the status of a machine or process. --- ### 1. Technical Specifications The "AP" series generally refers to miniature pilot lights. Below is a breakdown of the typical specifications for an AP2N-R model: | Feature | Specification | | :--- | :--- | | **Series** | AP Series (Miniature Pilot Lights) | | **Mounting Hole Size** | 12mm (Diameter) | | **Lens Color** | **Red** (Indicated by the "R" suffix) | | **Illumination Type** | LED (Integrated) | | **Lens Shape** | Round / Dome | | **Terminal Type** | Solder Terminal or Tab Terminal | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying the exact variant: * **AP**: Miniature Pilot Light series. * **2**: Designates the physical size and mounting style (12mm). * **N**: Represents the specific body style or revision. * **R**: **Red** lens color. (Other options usually include G: Green, A: Amber, W: White, S: Blue). --- ### 3. Key Electronic Characteristics These parts are designed for reliability in industrial environments. Key electronic features include: 1. **Operating Voltage:** They are typically available in specific voltage ratings such as 6V, 12V, or 24V DC. Some AC versions exist, but DC is most common for the 12mm size. 2. **Built-in Current Limiting:** Unlike a raw LED, the AP2N-R contains internal resistors, allowing it to be connected directly to the rated power source without burning out. 3. **Polarity:** As an LED-based device, polarity usually matters (Positive to Anode, Negative to Cathode), though some industrial versions include bridge rectifiers to make them non-polar. 4. **Longevity:** Rated for approximately 50,000+ hours of continuous operation. --- ### 4. Common Applications * **Status Indicators:** Showing "Fault" or "Stop" conditions (common for Red). * **Control Panels:** Used in compact PLC interfaces and operator stations. * **Medical Equipment:** Due to their small 12mm footprint. * **Testing Rigs:** Providing visual confirmation of circuit activity.
