The **M2UDS2-FWB-R** is a specific part number typically associated with **IDEC Corporation’s** line of miniature pilot lights and switches. This particular component belongs to the **M2 series**, known for its compact design and high reliability in industrial control panels. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Component Overview The M2UDS2-FWB-R is an **LED-illuminated Pilot Light**. These are used as status indicators on machinery to notify operators of power status, faults, or process completion. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | IDEC M2 Series (Miniature Indicator) | | **Body Shape** | Square (S2) | | **Illumination Type** | LED | | **Color** | Red (R) | | **Input Voltage** | Typically 24V AC/DC (Standard for FWB suffix) | | **Mounting Hole** | 12mm diameter | | **Protection Rating** | IP40 (Dustproof) | | **Termination** | Solder terminals / Tab terminals | --- ### 3. Part Number Breakdown (Nomenclature) To understand the electronic function, we can dissect the part number: * **M2**: The series designation (IDEC 12mm Miniature series). * **U**: Unit type (Indicator/Pilot light). * **D**: LED Lamp type. * **S2**: Square bezel/operator shape (approx. 18mm x 18mm). * **FWB**: This designates the **Full Voltage** type with a specific internal resistor/circuitry (usually rated for 24V). * **R**: Lens and LED color (Red). --- ### 4. Key Electronic Characteristics * **Integrated Resistor:** Unlike bare LEDs, this unit includes internal current-limiting circuitry, allowing it to be connected directly to a power source (e.g., 24V) without burning out. * **Low Power Consumption:** Because it utilizes LED technology rather than incandescent bulbs, it has a very low current draw (typically <20mA) and a long operational life (approx. 50,000 hours). * **Polarity:** For DC applications, polarity must be observed at the terminals, although many modern IDEC units include bridge rectifiers for AC/DC compatibility. --- ### 5. Common Applications 1. **Control Panels:** Small-scale industrial interfaces where space is limited. 2. **Medical Equipment:** Due to its compact 12mm mounting footprint. 3. **Alarm Systems:** Visual signaling for error states or safety warnings.
