The GTB6-N1211 is a compact NPN Photo Sensor from Sick, designed for precise and reliable object detection in industrial automation. Known for its robust design and stable optical performance, this Sick Photoelectric Sensor ensures dependable detection even in demanding environments such as packaging, robotics, and assembly lines.
The Sick GTB6-N1211 operates on a photoelectric proximity sensing principle with background suppression, enabling it to detect targets accurately while ignoring reflective surfaces behind the object. It uses a high-intensity PinPoint LED light source that emits visible red light at 650 nm, forming a sharp 6 mm light spot at 100 mm for precise alignment. With a sensing range of 35 mm to 140 mm (and up to 250 mm maximum), it offers flexible performance for short- and mid-range detection tasks. This sensor provides an NPN digital output and supports both light and dark switching modes, selectable via a dedicated mode switch. Operating at a response time of less than 625 Β΅s and a switching frequency of 1,000 Hz, the GTB6-N1211 Photo Sensor ensures high-speed detection in fast-moving production lines. It runs efficiently on a 10β30 V DC power supply with a low current consumption of 30 mA, maintaining energy efficiency and reliability. Built in a durable ABS/PC rectangular housing with a PMMA optical window, this sensor provides strong protection against dust and moisture with its IP67-rated enclosure. The compact form factor (12 Γ 31.5 Γ 21 mm) and pre-wired 3-wire, 2-meter cable connection make installation fast and convenient in tight automation setups.
The Sick GTB6-N1211 NPN Photo Sensor is ideal for packaging machinery, conveyor systems, labeling applications, and robotic detection tasks. In industrial production lines, it offers stable detection of transparent films, small components, or colored materials without being affected by background reflectivity. The fast response time and high switching frequency allow accurate object counting and position control in high-speed conveyors. Maintenance engineers appreciate its long operational life, easy setup, and consistent signal output, which reduce downtime and calibration needs. The GTB6-N1211 also performs reliably in challenging environments, with an operating temperature range from β25 Β°C to +55 Β°C and resistance to vibration, oil, and dust. Whether used in precision assembly, bottling lines, or automated inspection systems, the Sick GTB6-N1211 Photo Sensor delivers the performance, stability, and endurance required in modern automation environments.
For engineers seeking additional technical information, the GTB6-N1211 datasheet and GTB6-N1211 manual provide complete details on wiring, installation, and configuration. The GTB6-N1211 price offers excellent value, combining Sickβs globally trusted build quality with advanced sensing performance. With decades of innovation in industrial sensor technology, Sick continues to set benchmarks in reliability, making the Sick GTB6-N1211 NPN Photo Sensor a proven solution for precise, efficient, and trouble-free automation.
