In electronic assembly, sensors must recognize tiny and often reflective parts that move quickly across compact work areas. The SICK GTB2S-E1331 provides precise detection with its narrow, focused red LED beam, allowing robotic grippers to identify the presence and position of each component. Its background suppression minimizes interference from conveyor surfaces, while the ultra-fast response time ensures accurate timing for pick-and-place operations. The compact body fits easily on robotic arms or feeders, helping manufacturers increase throughput without sacrificing accuracy.
In plastic molding or metal stamping lines, detecting items with shiny or dark surfaces can be challenging. The GTB2S-E1331 overcomes this with strong background suppression and a stable PinPoint LED that differentiates between reflective materials and conveyor belts. Even in dusty or oily factory environments, its IP67-rated design maintains reliable operation. This stability minimizes false triggers and ensures consistent product flow, making it a dependable choice for packaging and sorting equipment running at high speeds.
Semiconductor fabrication requires extreme accuracy when handling thin wafers or films. The GTB2S-E1331’s small optical spot enables precise edge detection and alignment verification without affecting delicate materials. Its rapid signal response allows smooth synchronization with robotic handling systems, improving overall process accuracy. Compact size and vibration resistance make it ideal for integration inside production tools where space and precision are equally critical. This results in reduced waste, better alignment, and consistent production yield.
Modern robotic cells demand sensors that are both lightweight and powerful. The GTB2S-E1331 fits seamlessly into these systems, providing dependable part presence or tool-position feedback. Its rugged ABS housing withstands vibration and temperature changes, while the fast switching capability supports continuous movements. With its small mounting footprint, it can be placed near moving arms or end effectors to detect items in tight zones. This enables precise coordination between motion and sensing, improving safety and efficiency in compact automation setups.
