The **WLS28-2X430S** is a high-performance industrial LED strip light manufactured by Banner Engineering. The "430" indicates a nominal length of 430mm, and the "S" typically denotes a built-in ON/OFF toggle switch. Below is a breakdown of the electronic specifications and components of this device. --- ### 1. Technical Specifications The following table summarizes the primary electrical characteristics of the WLS28-2 series. | Parameter | Specification | | :--- | :--- | | **Operating Voltage** | 12V DC to 30V DC | | **Current Consumption** | Max 1.0 A (at 12V) / 0.4 A (at 30V) | | **Power Consumption** | ~12 Watts (Nominal) | | **Light Color** | Cool White (standard) | | **Color Temperature** | 6000K to 7100K | | **Connection Type** | 4-pin M12/Euro-style QD (Quick Disconnect) | --- ### 2. Key Electronic Components #### A. LED Array * **Technology:** High-density Surface Mount (SMD) LEDs. * **Driver Circuitry:** Includes a constant-current driver that ensures consistent light output regardless of voltage fluctuations within the 12-30V range. This protects the LEDs from overcurrent conditions. #### B. The "S" (Switch) Mechanism * **Toggle Switch:** This model features an integrated manual rocker switch. * **Circuit Integration:** The switch is wired in series with the internal driver, allowing local control without needing to modify the PLC or external controller logic. #### C. Internal Protection * **Reverse Polarity Protection:** Prevents damage if the DC power leads are connected backwards. * **Overvoltage Protection:** Designed to withstand standard industrial electrical noise and spikes. --- ### 3. Wiring and Pinout (M12 Connector) The device uses a standard 4-pin M12 connector. While 4 pins are present, usually only two are utilized for basic operation. | Pin Number | Wire Color | Function | | :---: | :--- | :--- | | 1 | Brown | +12V DC to +30V DC | | 2 | White | Not Used (usually) | | 3 | Blue | DC Common (Ground) | | 4 | Black | Not Used (unless PWM dimming is supported) | --- ### 4. Construction & Housing * **Casing:** Clear or diffuse polycarbonate window with an aluminum inner spine for heat dissipation. * **Environmental Rating:** IP50 (due to the manual switch; non-switch versions are often IP67/IP69K). * **Daisy-Chaining:** Many versions allow for "Cascadable" wiring, where multiple units are connected in series. However, the total current must not exceed the maximum rating of the first cable (typically 4 Amps). ---
