The **WLS28-2..285S** is a part of the Banner Engineering WLS28-2 series of industrial LED strip lights. This specific model is a **285mm (stand-alone)** version, designed for rugged industrial environments. Below is the technical breakdown of its electronic components and specifications. --- ### 1. Key Electronic Specifications The "S" suffix indicates a **Stand-alone** model with an integrated ON/OFF switch. | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 12V DC to 30V DC | | **Current Consumption** | ~0.33A at 12V DC / ~0.14A at 30V DC | | **Power Consumption** | Approx. 4 Watts | | **Light Color** | Cool White (standard) | | **Lumens** | Approx. 475 Lumens | | **Connection Type** | 4-pin M12 Quick Disconnect (Euro-style) | --- ### 2. Internal Electronic Components #### A. LED Array The unit features high-intensity surface-mount LEDs mounted on a linear PCB. These LEDs are binned for color consistency and are driven by a constant current circuit to ensure uniform brightness regardless of voltage fluctuations (within the 12-30V range). #### B. Integrated Driver Unlike simple LED strips, the WLS28-2 contains an **internal switching regulator**. - **Regulation:** It maintains constant light output even if the supply voltage drops or spikes. - **Protection:** Includes reverse polarity protection and transient voltage suppression to survive industrial electrical noise. #### C. Switching Mechanism (The "S" Feature) The "S" in the part number denotes an **integrated physical toggle switch**. - The switch is a sealed, industrial-grade component located at the end of the housing. - It interrupts the internal DC circuit to provide manual control independent of the PLC or external controller. --- ### 3. Wiring Configuration (M12 Connector) The device uses a standard 4-pin M12 male connector. Even though it is a DC device, it follows a specific pinout for industrial standardization. | Pin | Wire Color | Function | | :--- | :--- | :--- | | **1** | Brown | +12 to 30V DC | | **3** | Blue | DC Common (Ground) | | **4** | Black | Not Used (usually) | | **2** | White | Not Used (usually) | --- ### 4. Environmental Protection The electronics are encased in a rugged housing that provides significant protection: - **IP Rating:** IP50 (Standard models with switch). - **Housing:** Clear or diffuse polycarbonate window with an aluminum inner spine for heat dissipation. - **Operating Temp:** -40°C to +70°C (-40°F to +158°F). ---
