The **M2UDS-A1B-R** is a specific part number from **Omron**, belonging to their **M2UJ** series of indicators. These are commonly used in industrial control panels to provide visual feedback for automated systems. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Indicator / Pilot Light | | **Model Series** | M2UJ / M2UDS | | **Shape** | Square (Body/Lens) | | **Illumination Method** | LED (Standard) | | **Input Voltage** | 24 VDC/VAC (Typical for A1B-R configuration) | | **Color** | Red (Indicated by the "R" suffix) | | **Mounting Hole Size** | Approx. 16mm (Standard industrial cut-out) | --- ### 2. Detailed Electronic Characteristics #### A. Internal Circuitry The device consists of a high-efficiency **LED array** protected by internal current-limiting resistors. This allows it to be connected directly to a power source without requiring external resistance, provided the voltage matches the rated specification. #### B. Terminal Configuration * **Polarity:** Since it is often designed for both AC and DC, the terminals are usually non-polarized or clearly marked for DC applications depending on the internal rectification. * **Connection Type:** Typically uses solder terminals or quick-connect tab terminals. #### C. Power Consumption * **Current Draw:** Low power consumption, usually ranging between **10mA to 20mA**. * **Heat Dissipation:** Minimal, making it ideal for dense control panels where thermal management is a concern. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying replacement parts: 1. **M2UDS:** The series designation (Square type indicator). 2. **A1B:** Specifies the specific body design, terminal style, and operating voltage. 3. **R:** Specifies the **Red** lens and LED color. --- ### 4. Typical Applications * **Status Indicators:** To show that a machine is "Running" or in an "Error" state. * **Control Panels:** Integrated into PLC (Programmable Logic Controller) outputs to provide visual cues to operators. * **User Interfaces:** Used in kiosks or industrial machinery where ruggedness and long life (due to LED technology) are required.
