The **M2UDS2-A5W-R** is a specific model of an **Industrial Indicator Light** (Pilot Light) manufactured by **IDEC**. It belongs to the **M2 series** of miniature indicators, typically used in control panels for status signaling. --- ### 1. Technical Specifications The following table outlines the primary electronic and physical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Series** | M2 Series (Miniature) | | **Mounting Hole Size** | 10mm (Round) | | **Voltage (Input)** | 12V - 24V AC/DC | | **Illumination Type** | LED (High-brightness) | | **Lens Shape** | Square | | **Lens Color** | White (W) | | **Terminal Type** | Solder Terminal | | **Housing Color** | Black | --- ### 2. Detailed Electronic Components The device is not a single electronic part but an assembly consisting of several sub-components: #### A. The LED Unit The "A5" designation usually refers to the internal LED lamp. Unlike incandescent bulbs, this LED unit includes: * **Current Limiting Resistor:** Built-in to allow direct connection to the rated voltage without burning out the diode. * **Rectifier Circuit:** Allows the unit to operate on both AC and DC polarity. #### B. Housing & Terminals * **Terminals:** Usually gold-plated or silver-plated to ensure low contact resistance and prevent oxidation. * **Insulation:** The body is made of high-grade plastic (polyamide or polycarbonate) with high dielectric strength to prevent short-circuiting to the panel. #### C. Optical Lens * The "W" in the part number stands for **White**. * The lens acts as a diffuser to spread the LED light evenly across the square surface, preventing "hot spots" (intense bright dots). --- ### 3. Part Number Breakdown Understanding the suffix helps in identifying the exact electronic configuration: * **M2:** Series identifier (10mm mounting). * **U:** Unit type (Indicator). * **DS2:** Square lens shape. * **A5:** Integrated LED lamp for 12-24V range. * **W:** White lens color. * **R:** This often denotes a specific packaging or a minor revision in IDEC's catalog (Red LEDs sometimes use R, but in this specific sequence, it usually identifies a series revision or terminal style). --- ### 4. Circuit Implementation When integrating this into a system, the wiring is straightforward: ```python # Conceptual Wiring Diagram [Power Source (+)] ---- [Switch/PLC Output] ---- [Terminal 1] (M2UDS2) [Power Source (-)] ------------------------------ [Terminal 2] ```
