The **LEDA70SWD** is a high-performance industrial LED bar light typically used in machine vision applications. It is designed to provide intense, uniform linear illumination for inspection tasks. --- ### 1. Key Technical Specifications The electronics of the LEDA70SWD are engineered for durability and precise control. | Feature | Specification | | :--- | :--- | | **Input Voltage** | 24V DC | | **Current Consumption** | ~500mA to 700mA (model dependent) | | **Light Color** | White (W) | | **Illumination Length** | 70mm | | **Connector Type** | M12 4-pin or 5-pin male (standard industrial) | | **IP Rating** | IP50 (standard) / IP67 (optional water-resistant) | --- ### 2. Electronic Components & Functionality #### A. The LED Array The "70" in the model name refers to the 70mm active area. This contains a high-density row of Surface Mount Device (SMD) LEDs. * **Phosphor Coating:** Since it is a "White" LED, it uses Blue LED dies coated with yellow phosphor. * **Circuit Topology:** LEDs are usually arranged in series-parallel strings to balance current draw and ensure that a single LED failure doesn't kill the entire bar. #### B. Built-in Driver (Constant Current) Unlike consumer LED strips, the LEDA70SWD includes an internal **Constant Current Driver**. * **Regulation:** It stabilizes the current despite fluctuations in the 24V DC input. * **Thermal Protection:** Includes circuitry to throttle power if the internal temperature exceeds safe limits, preventing premature LED degradation. #### C. Control & Dimming (The "D" Suffix) The "D" in the model often signifies **Dimming** or **Digital control** capabilities. * **Strobe Support:** The electronics are designed to handle high-speed switching. * **Analog/PWM Control:** It can typically be dimmed via a 0-10V analog signal or a Pulse Width Modulation (PWM) signal through the control pin. --- ### 3. Pinout Configuration (M12 Connector) Typical wiring for industrial vision lights like the LEDA70 series: | Pin Number | Color | Function | | :--- | :--- | :--- | | **1** | Brown | +24V DC | | **2** | White | Control/Dimming (0-10V or PWM) | | **3** | Blue | DC Common (GND) | | **4** | Black | Strobe/Trigger (Active High/Low) | --- ### 4. Integration Example To control this part using a PLC or Vision Controller, you would typically use a simple output circuit: ```python # Conceptual logic for strobing the LEDA70SWD if camera_trigger == TRUE: set_pin_4(HIGH) # Turn on Light wait(exposure_time) set_pin_4(LOW) # Turn off Light ```
