The **LR5-102WENW-R** is a specific model from the Patlite LR5 series of modular signal towers (stack lights). This model is designed for industrial automation to provide visual status indication. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Number** | LR5-102WENW-R | | **Diameter** | 50mm | | **Number of Tiers** | 1 Tier (Red LED) | | **Rated Voltage** | 24V DC | | **Mounting Style** | Direct Mount (W) | | **Wiring Connection** | Lead Wire (E) | | **Body Color** | Off-white (N) | | **Lens Type** | No Flashing / No Buzzer (W) | --- ### 2. Electronic Components & Design The internal electronics of the LR5-102WENW-R are engineered for durability in harsh industrial environments: #### A. LED Unit Architecture * **High-Intensity LEDs:** Uses multi-die LED chips arranged to provide 360-degree visibility. * **Internal Reflector:** A specialized "inner lens" design enhances light diffusion, ensuring the light is visible even from long distances or under bright factory overhead lights. #### B. Protection Circuitry * **Reverse Polarity Protection:** Prevents damage to the internal LEDs if the 24V DC wires are connected incorrectly. * **Voltage Regulation:** Built-in resistors and regulating circuits ensure the LEDs operate at a constant current, preventing flickering and extending the lifespan (rated for approx. 50,000 hours). #### C. Control Interface * **Dry Contact / Open Collector:** The unit is compatible with NPN or PNP transistor outputs from PLCs (Programmable Logic Controllers). * **Current Consumption:** This model is highly efficient, typically drawing around **50mA** for the single red tier. --- ### 3. Build & Environmental Rating The electronic housing is designed to meet strict industrial standards: * **IP Rating:** **IP65** (Dust-tight and protected against water jets), provided it is installed correctly. * **Vibration Resistance:** Tested to withstand up to **0.7G**, making it suitable for mounting directly on heavy machinery. * **Operating Temperature:** Effective from **-20°C to +50°C**. --- ### 4. Wiring Information The unit uses a color-coded lead wire system for simple integration: | Wire Color | Signal / Function | | :--- | :--- | | **Red** | Red LED Tier Control | | **Yellow** | Common Line (Power) | | **Gray/Other** | Internal ground/logic (depending on specific NPN/PNP setup) | ---
