The **LR5-102LENW-R** is a high-performance LED signal tower (stack light) manufactured by **Patlite**. It is part of the LR5 series, which is designed for industrial automation to provide visual and audible status indications for machinery. --- ## Technical Specifications The model number can be broken down to understand its specific electronic configuration: | Component Code | Specification | Description | | :--- | :--- | :--- | | **LR5** | 50mm Diameter | The outer diameter of the lens/body units. | | **1** | 1 Tier | This specific model comes with one LED module. | | **02** | 24V DC | Operates on standard industrial direct current. | | **LE** | LED Unit | High-intensity LED module (Multi-color capable or single). | | **NW** | Off-White Body | Non-flashing (Continuous light) and no buzzer. | | **R** | Red | The color of the LED module. | --- ## Electronic Characteristics ### 1. Power and Control * **Rated Voltage:** 24V DC. * **Operating Voltage Range:** 21.6V to 26.4V DC. * **Current Consumption:** Typically around **40mA** to **55mA** for the red LED unit. * **Input Type:** Bi-polar (NPN/PNP open collector compatible), allowing it to interface with various PLC outputs. ### 2. LED Technology * **Light Source:** High-brightness LEDs arranged to provide 360-degree visibility. * **Lens Design:** The "LE" designation refers to an enhanced lens design that diffuses light more effectively than older models (like the LME series). ### 3. Protection and Durability * **IP Rating:** **IP65** (Dust-tight and protected against water jets), provided it is installed correctly with the O-rings. * **Vibration Resistance:** Designed to withstand industrial environments with a resistance of up to 19.6 $m/s^2$. --- ## Wiring Diagram (General Logic) The device uses a color-coded wiring system to simplify integration with control panels. ```yaml Wiring Logic: - Red Wire: Connect to Red LED Signal (+24V for PNP / 0V for NPN) - Yellow/Gray Wire: Common Power Supply (Depends on NPN/PNP setup) - Protection: Internal diode protection against reverse polarity. ``` --- ## Key Features * **Modular Design:** The "Twist-and-Lock" system allows the electronic modules to be reconfigured or replaced without tools. * **Environmental Compliance:** RoHS compliant and CE marked for global industrial standards.
