The **LPA-14MA-R** is a specific electronic component, typically categorized as a **Panel Mount LED Indicator** or a specialized signal lamp. These parts are commonly used in industrial control panels, telecommunications equipment, and consumer appliances to provide visual status feedback. --- ### 1. Technical Specifications Below are the typical technical parameters associated with this component series: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | LED Indicator Light | | **Color** | Red (indicated by the "-R" suffix) | | **Mounting Type** | Panel Mount (Snap-in or Threaded) | | **Terminal Type** | Solder Tabs or Wire Leads | | **Body Material** | Plastic (often Polycarbonate or Nylon) | | **Lens Style** | Round / Domed | --- ### 2. Electronic Characteristics To integrate this part into a circuit, you must consider its electrical requirements: * **Forward Voltage ($V_f$):** Typically ranges from **1.8V to 2.2V** for the Red LED element, though many panel indicators include an internal resistor for 12V or 24V applications. * **Operating Current ($I_f$):** Standard operation is usually at **20mA**. * **Polarity:** As a Diode-based part, it is polarity sensitive. The longer lead or the marked terminal is the Anode (+), and the shorter/flat-side terminal is the Cathode (-). * **Luminous Intensity:** Designed for high visibility even in ambient light, providing a focused "point source" of red light. --- ### 3. Structural Components The "LPA" designation often refers to the assembly housing: 1. **LED Die:** The semiconductor material that emits red light. 2. **Internal Resistor (Optional):** Some versions include a built-in current-limiting resistor to allow direct connection to DC power supplies. 3. **Housing:** A protective shell that secures the LED to a chassis or panel. 4. **Diffuser/Lens:** The red-tinted cap that protects the LED and disperses the light for a wider viewing angle. --- ### 4. Common Applications * **Power Indicators:** Showing when a device is "ON." * **Fault Alarms:** Indicating a system error or emergency stop. * **Status Monitors:** Used in rack-mounted servers or industrial PLCs.
