The **M2UDS2-K0-R** is a specific part number typically associated with **IDEC Corporation’s** line of miniature electronic components, specifically within their **M2 series of pilot lights and indicators**. Below is a detailed breakdown of the electronic and mechanical characteristics of this component. --- ### 1. Component Overview The M2UDS2-K0-R is a **Square LED Indicator/Pilot Light**. These are commonly used in control panels, instrumentation, and industrial machinery to provide visual feedback to operators. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | M2 Series (Miniature) | | **Shape** | Square (S2 designation) | | **Mounting Hole** | 8mm Diameter | | **Input Voltage** | Typically 24V DC (Standard for K0 series) | | **Illumination Type** | LED (High brightness) | | **Color** | Red (R suffix) | | **Termination** | Solder terminals | | **Current Draw** | Low (Approx. 7mA - 15mA depending on voltage) | --- ### 3. Electronic Architecture The internal electronic structure of the M2UDS2-K0-R consists of three primary elements: 1. **Light Emitting Diode (LED):** The core light source. Unlike incandescent bulbs, this is solid-state, vibration-resistant, and has a long lifespan (approx. 50,000+ hours). 2. **Current-Limiting Resistor:** Built into the housing to ensure the LED operates safely at the rated voltage without burning out. 3. **Reverse Polarity Protection:** Most IDEC LED units include a diode to protect the component if the DC leads are connected backwards. ### 4. Part Number Breakdown (Nomenclature) Understanding the alphanumeric code helps in identifying the specific electronic requirements: * **M2:** The series name (Miniature 8mm). * **U:** Indicates the unit type (Indicator). * **D:** LED Illumination. * **S2:** 10mm x 10mm Square bezel size. * **K0:** Voltage rating (Commonly represents 24V DC for this series). * **R:** Lens color (Red). --- ### 5. Installation & Wiring The device is designed for panel mounting. Below is a simple representation of the electrical connection: ```text [Positive Terminal (+)] ----> [Internal Resistor] ----> [LED] ----> [Negative Terminal (-)] ``` * **Terminal Type:** Solder terminals require heat-shrink tubing for industrial safety to prevent short circuits. * **Panel Thickness:** Typically supports panels from 0.5mm to 6mm.
