Photoelectric Proximity Sensor GTB10-N1211 SICK – 950 mm Sensing Range, NPN, IP67
Overview:
The GTB10-N1211 from SICK is a photoelectric proximity sensor with background suppression (BGS) offering a maximum sensing distance of 950 mm. It features NPN output, a PinPoint red LED (625 nm), and an IP67 protection rating. Its compact design and 5-turn potentiometer adjustment make it suitable for conveyors, packaging machines, logistics systems, and industrial automation applications.
Product Overview of the Photoelectric Proximity Sensor GTB10-N1211
The GTB10-N1211 belongs to SICK’s G10 series and utilizes background suppression technology. This enables highly reliable object detection with minimal influence from the background or variations in object surface color and reflectivity.
With a focused light spot of Ø 8 mm at 700 mm and precise 5-turn potentiometer adjustment, the sensor delivers excellent performance in demanding industrial environments. Its compact dimensions (20 × 50 × 39 mm), IP67 rating, and wide operating temperature range (–30 °C to +60 °C) ensure stable operation even under dust, moisture, and mechanical vibration.

Applications of the GTB10-N1211 in Industry
- Packaging & Food Processing Lines: Background suppression allows precise differentiation between products and the conveyor belt or background, preventing false detections. The 1,000 Hz switching frequency and ≤ 500 µs response time support high-speed packaging, labeling, and bottling lines.
- Logistics & Material Sorting: The long 950 mm sensing range is ideal for wide conveyor systems, pallet detection, and automated sorting. Light/dark switching can be easily configured for bright or dark packaging materials.
- Automotive & Mechanical Parts Manufacturing: The precise Ø 8 mm PinPoint light spot and 5-turn potentiometer enable accurate detection of metal parts on jigs, fixtures, or assembly lines—even on gray (18% remission) or black (6% remission) surfaces.
- Electronics & Semiconductor Industry: The focused light spot ensures reliable detection of small components on SMT lines or presence checking of PCBs without interference from surrounding backgrounds.
- Pharmaceutical & Chemical Machinery: IP67 protection guards against dust and water splash in cleanroom-adjacent environments. The wide temperature range supports cold storage and temperature-controlled production areas.
