The **WL50SWSSL5PWMQ** is a high-performance LED work light manufactured by **Banner Engineering**. It belongs to the WL50 series, specifically designed for industrial environments requiring high-intensity illumination with dimming capabilities. --- ### 1. Technical Specifications The part number breaks down into specific electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Light Color** | Cool White (SWS) | | **Input Voltage** | 12V DC to 30V DC | | **Control Interface** | Pulse Width Modulation (PWM) | | **Connection Type** | 5-pin M12 Quick Disconnect (Q) | | **Lens Material** | Polycarbonate (L5 - 5-degree lens) | | **Environment Rating** | IP67, IP69K | --- ### 2. Electronic Component Breakdown #### A. PWM Dimming Interface The "PWM" designation is the most critical electronic feature. This allows the light intensity to be controlled via a Square Wave signal. * **Duty Cycle Control:** By varying the percentage of "on" time versus "off" time in the signal, the brightness can be adjusted from 0% to 100%. * **Integration:** This is typically interfaced with a PLC (Programmable Logic Controller) or a dedicated PWM dimmer module. #### B. LED Driver Circuitry Inside the housing, the device contains a constant-current driver. * **Voltage Regulation:** It accepts a wide range of DC input (12-30V), ensuring consistent brightness even if the power supply fluctuates. * **Thermal Management:** The internal electronics include thermal foldback protection to prevent the LEDs from overheating, extending the lifespan of the unit. #### C. Optical Design (L5) The "L5" refers to the **5-degree lens**. Electronically, this means the light output is concentrated into a tight, high-intensity spot beam rather than a wide flood. This is ideal for long-distance illumination or precision inspection. --- ### 3. Pinout Configuration (5-pin M12) To integrate this part into a circuit, the following wiring logic is standard for Banner 5-pin PWM lights: | Pin | Wire Color | Function | | :--- | :--- | :--- | | 1 | Brown | +12V DC to 30V DC | | 2 | White | Not Used / Control (Depending on model) | | 3 | Blue | DC Common (Ground) | | 4 | Black | PWM Control Input | | 5 | Gray | Not Used | --- ### 4. Key Advantages * **Ruggedness:** The electronics are fully encapsulated (potted), making the light resistant to vibration, shock, and high-pressure water washdowns. * **Efficiency:** Uses high-efficacy LEDs that provide significant lumens-per-watt compared to traditional halogen work lights.
