The GTB2S-N1311 photoelectric sensor represents a significant advancement in industrial automation technology, designed to deliver reliable detection across diverse applications. This sensor utilizes modulated infrared light to detect objects, minimizing interference from ambient light and ensuring consistent performance in challenging environments. Its compact housing, constructed from durable materials, provides IP67 protection against dust and water ingress, making it suitable for use in manufacturing lines, packaging systems, and material handling equipment.
Operating on the diffuse reflective principle, the GTB2S-N1311 emits a light beam that reflects off target objects back to the receiver. This design allows for easy installation without requiring a separate reflector, reducing setup complexity. The sensor features a sensing range of up to 300 mm, adjustable via a potentiometer to accommodate various object sizes and surface properties. A stable response time of 1 ms enables detection of fast-moving items, critical for high-speed production processes.
Key technical specifications include a 12-24 VDC power supply, NPN open-collector output, and a red LED indicator for operational status. The housing incorporates M8 connectors for quick wiring, while the built-in reverse polarity protection prevents damage from incorrect connections. Environmental resilience is ensured with an operating temperature range of -25°C to 55°C, allowing deployment in unheated warehouses or outdoor settings.
In practical applications, the GTB2S-N1311 excels in detecting transparent bottles, colored labels, and metallic components. For instance, in beverage bottling plants, it accurately identifies glass containers on conveyor belts, triggering filling or capping mechanisms. Logistics centers employ these sensors to count cartons on sorting lines, with the adjustable sensitivity avoiding false triggers from dust or vibration. Maintenance requirements are minimal due to the solid-state design, though periodic lens cleaning is recommended in dusty conditions to maintain optimal performance.
Integration with programmable logic controllers (PLCs) is straightforward using the sensor’s standard output signals. Users can connect multiple units to monitor complex assembly stages, such as verifying part presence in automotive manufacturing. The device complies with international standards including CE and RoHS, ensuring safety and environmental compatibility. Compared to ultrasonic or capacitive alternatives, photoelectric sensors like the GTB2S-N1311 offer superior precision for non-contact detection of small objects, though they may require calibration for highly reflective surfaces.
Future developments in sensor technology may enhance the GTB2S-N1311’s capabilities, such as adding IO-Link communication for real-time diagnostics. Currently, its balance of cost-effectiveness and reliability makes it a preferred choice for engineers seeking to automate quality control or inventory management tasks. Proper installation involves aligning the emitter perpendicular to the target surface and testing under actual operating conditions to fine-tune detection thresholds.
