The **JAPD2-BJ-R** is a specific electronic component commonly used in industrial automation, particularly within the ecosystem of **IDEC Corporation**. It belongs to the **AP Series** of miniature pilot lights. Below is a detailed breakdown of its electronic characteristics and specifications. ### 1. Product Overview The JAPD2-BJ-R is a **12mm miniature LED pilot light**. Its primary function is to provide visual status indication for control panels, machinery, and electronic circuits. | Feature | Specification | | :--- | :--- | | **Series** | AP Series (Miniature Pilot Lights) | | **Mounting Hole** | 12mm (Round) | | **Illumination Type** | LED (High-brightness) | | **Lens Color** | Red (indicated by the "-R" suffix) | | **Lens Shape** | Dome / Round | | **Termination** | Solder Terminals | --- ### 2. Electronic Characteristics This component is designed for low-voltage DC applications and incorporates internal circuitry to protect the LED element. * **Operating Voltage:** Typically rated for **24V DC**. * **Current Consumption:** Low power consumption, usually between **7mA to 15mA**. * **Internal Protection:** It generally includes a built-in current-limiting resistor and a protection diode to prevent damage from reverse polarity. * **Life Expectancy:** Being LED-based, it offers a long operational life (approx. 50,000+ hours) compared to incandescent bulbs. --- ### 3. Structural Components The device is composed of three main electronic and physical sections: 1. **The Head (Lens):** A translucent red polycarbonate cover that diffuses light for wide-angle visibility. 2. **The Light Engine:** A high-efficiency LED chip soldered to a small internal PCB. 3. **The Housing/Terminals:** A flame-retardant plastic body with two gold-plated or silver-plated solder terminals for electrical connection. --- ### 4. Technical Drawing & Dimensions | Dimension | Value | | :--- | :--- | | Front Bezel Diameter | 15mm | | Mounting Depth | ~20mm to 25mm | | Panel Thickness | 0.5mm to 6mm | | Degree of Protection | IP65 (Waterproof/Dustproof from the front) | --- ### 5. Application Wiring Because this is a polarized DC device, wiring must be observed: * **Anode (+):** Connect to the positive 24V supply. * **Cathode (-):** Connect to the common/ground. ```circuit [+24V DC] ---- [Switch/PLC Output] ---- [Anode (+) JAPD2-BJ-R (-)] ---- [GND] ```
