Infrared diffuse photoelectric proximity sensor GTE10-N1221 SICK – 2 m Sensing Range, NPN, IP67
Overview:
The GTE10-N1221 is a photoelectric proximity sensor from SICK’s G10 series. It features an NPN output and a maximum sensing range of up to 2,000 mm. With IP67 protection, the sensor is designed for reliable operation in demanding industrial environments involving dust and moisture. It is an excellent choice for conveyor systems, logistics, packaging machinery, and automated production lines requiring long-range object detection with high stability.
Product Overview of the Photoelectric Proximity Sensor GTE10-N1221
The GTE10-N1221 operates on the energetic principle. The sensor emits infrared light and receives the light reflected directly from the target object without the need for a reflector. It uses an 850 nm infrared LED, which significantly reduces interference from ambient visible light and ensures stable performance at long distances.
The sensor supports sensitivity adjustment via a 270° potentiometer, Light ON / Dark ON switching, and comprehensive circuit protection (reverse polarity, short-circuit, and noise suppression). With a switching frequency of 1,000 Hz, it is well-suited for high-speed object detection in industrial automation applications.

Applications of the GTE10-N1221 in Industry
- Logistics & Automated Warehousing: The 2,000 mm infrared sensing range is ideal for monitoring goods on long conveyors, pallet detection, and automated gate control. Infrared light is minimally affected by ambient visible light conditions.
- Automotive & Heavy Machinery Manufacturing: Long sensing distance enables reliable monitoring of large components on welding, assembly, and quality inspection lines. Comprehensive circuit protection (A+B+C+D) withstands electromagnetic interference from welding robots and heavy machinery.
- Woodworking & Building Materials: The 850 nm infrared light effectively detects rough, uneven, or dark surfaces (such as raw wood or pressed boards) where red light sensors often struggle. IP67 rating protects against sawdust and debris.
- Industrial Packaging Lines: High switching frequency (1,000 Hz) and fast response time (≤ 500 µs) ensure precise detection of fast-moving products. The 270° potentiometer allows fine-tuning of the sensing range for different package sizes.
- Sorting Systems & Conveyors: The long 2,000 mm range allows flexible sensor installation away from hazardous areas, making it suitable for multi-lane sorting systems and wide conveyor belts in large manufacturing plants.
AUMI has supplied the GTE10-N1221 for numerous conveyor and sorting projects in industrial zones across Northern and Southern Vietnam, helping customers optimize installation distance and reduce maintenance costs compared to conventional sensing solutions.
