The **L58D-R2-W** is a specific model identifier typically associated with **Indicator Lights** or **LED Pilot Lamps**, often used in industrial control panels, medical devices, and instrumentation. Based on technical specifications for this series (often manufactured by companies like Leecraft or VCC), here is the breakdown of its electronic components and characteristics. --- ### 1. General Specifications The "L58" series denotes a rectangular, snap-fit indicator designed for easy mounting. | Feature | Specification | | :--- | :--- | | **Component Type** | LED Indicator / Pilot Light | | **Lens Shape** | Rectangular | | **Termination** | Wire Leads (indicated by the "-W") | | **Mounting Type** | Snap-in (Panel Mount) | | **Standard Hole Size** | ~0.500" x 0.600" (approximate) | --- ### 2. Part Number Breakdown The suffixing in these parts usually follows a specific logic: * **L58D**: The base series model (rectangular body). * **R2**: Typically refers to the **Resistor** configuration. In LED indicators, an internal resistor is required to limit current so the LED doesn't burn out when connected to specific voltages (e.g., 12V, 24V, or 125V). * **W**: Stands for **Wire Leads**. This means the part comes with pre-attached insulated copper wires (usually 6 inches) rather than quick-connect terminals or solder lugs. --- ### 3. Key Electronic Characteristics #### A. Internal Circuitry Unlike a bare LED, the L58D-R2-W is a complete assembly. It contains: 1. **The LED Chip:** The light source. 2. **Current Limiting Resistor:** Integrated inside the housing to allow direct connection to a power source. 3. **Rectifier Diode (Optional):** Some models include a diode if they are rated for AC (Alternating Current) usage to prevent reverse voltage damage. #### B. Electrical Ratings * **Voltage:** Depending on the exact "R2" sub-spec, these are commonly rated for **12V DC**, **28V DC**, or **125V AC**. * **Current Draw:** Usually very low, ranging from **10mA to 20mA**. * **Polarity:** If the unit is DC-rated, the wire leads will usually be color-coded (Red for Positive, Black for Negative). --- ### 4. Materials and Durability * **Housing:** Typically Nylon or Polycarbonate. * **Lens:** Translucent Polycarbonate, designed to diffuse the LED light for wide-angle visibility. * **Compliance:** Usually UL recognized and RoHS compliant for industrial safety. ---
