The **SBSI-B-AF-R3B-F6-R** is a specific part number belonging to the **Festo SBSI series** of vision sensors. These devices are integrated electronic systems that combine an image sensor, lighting, and processing logic into a single industrial housing. Below is an explanation of its electronic components and specifications. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Sensor Type** | CMOS Monochrome | | **Resolution** | 752 x 480 Pixels (Wide VGA) | | **Lens Focal Length** | 6 mm (Integrated) | | **Focus Type** | Autofocus (Electronic Control) | | **Light Color** | Infrared (IR) | | **Operating Voltage** | 24 V DC (+/- 10%) | | **Digital Inputs** | 2 (Configurable) | | **Digital Outputs** | 4 (Configurable) | | **Communication** | Ethernet (10/100 Mbit/s) | --- ### 2. Key Electronic Systems #### A. Image Sensing & Processing The core of the unit is a **CMOS global shutter sensor**. Unlike rolling shutters, a global shutter captures the entire frame at once, which is critical for high-speed industrial lines to avoid "motion blur" or skewing of moving parts. #### B. Integrated Lighting (Infrared) The **"R3"** in the part number designates **Infrared light (850 nm)**. * **Electronic Advantage:** IR is less sensitive to ambient light changes in a factory and does not distract human operators with flashing lights. * **Pulse Control:** The electronics synchronize the light pulse with the sensor's exposure time to maximize contrast while minimizing power consumption. #### C. Electronic Autofocus The **"AF"** signifies an internal liquid lens or voice-coil motor mechanism that allows the focal plane to be adjusted via software. This eliminates the need for manual mechanical adjustments if the distance to the target object changes. #### D. Input/Output (I/O) Logic The device features an M12 12-pin connector for power and I/O. * **Opto-isolation:** The digital inputs are typically opto-isolated to protect internal circuitry from voltage spikes common in industrial environments. * **Logic Switching:** It supports PNP/NPN switching logic through configuration. --- ### 3. Connectivity & Protocols The electronic interface supports industrial communication for integration into PLCs (Programmable Logic Controllers): * **Ethernet/IP:** For high-speed data exchange with Allen-Bradley or similar controllers. * **TCP/IP & UDP:** For sending raw image data or result strings to a PC or server. * **FTP/SMB:** For electronic archiving of images (Pass/Fail logs). ---
