Product Specification
1. High-Precision Diffuse Reflection with Background Suppression
The SICK GTB6-N4212 is a compact photoelectric proximity sensor engineered for industrial automation applications requiring reliable object detection in challenging environments. Leveraging background suppression technology, it distinguishes objects from their surroundings by measuring the triangulation of reflected light, ensuring accurate detection even in cluttered or reflective settings . With a detection range of 5–250 mm for natural objects and a visible red PinPoint LED light source (650 nm), it offers a precise light spot size of ø6 mm at 100 mm, enabling detection of small parts or irregular surfaces . The sensor supports PNP output with light/dark switching modes, providing flexibility for diverse applications like conveyor belt monitoring, packaging quality control, or automotive assembly line automation. Its IP67-rated housing (IP69K for stainless steel variants) ensures resistance to dust, water, and chemicals, making it suitable for washdown environments in food processing or pharmaceutical industries .
2. Rugged Design and Easy Integration
Built with ABS/PC plastic housing and reinforced metal inserts for secure mounting, the GTB6-N4212 combines durability with space-saving design (12 x 31.5 x 21 mm). The sensor features a 5-turn mechanical potentiometer for quick distance adjustment and visible LED indicators for real-time status monitoring . It operates on 10–30 VDC power supply with reverse polarity protection, consuming ≤30 mA while delivering a response time of 625 µs and 1,000 Hz switching frequency . The M8 male connector simplifies installation, and the sensor includes a stainless steel mounting bracket (1.4301/304) for stable positioning in confined spaces. Compliant with CE and RoHS standards, it meets global safety requirements for industrial use .
3. Versatile Applications and Advanced Features
Ideal for material handling and logistics, the GTB6-N4212 excels in detecting empty pallets, tracking package alignment, or monitoring fill levels in bulk storage systems. Its background suppression capability eliminates false triggers from reflective backgrounds, making it indispensable for automotive part sorting or electronics assembly lines . The sensor’s PinPoint LED technology ensures high immunity to ambient light interference, while the SICK ASIC chip enhances signal processing for consistent performance . Optional stainless steel housing variants (e.g., G6 Inox) further extend its usability in corrosive environments, supporting industries like chemical processing or marine automation. With short-circuit protection and a 100,000-hour lifespan, the GTB6-N4212 balances reliability with low maintenance costs, delivering long-term value for industrial automation projects .
