SICK Background Suppression Photoelectric Sensor, Barrel Style, 20 mm to 150 mm Detection Range, NPN Output GRTB18S-N2412V

SICK GRTB18S-N2412V Background Suppression Photoelectric Sensor is a high-performance barrel-style sensor designed for precise background suppression with a detection range from 20 mm to 150 mm. The sensor features an industrial-grade stainless steel housing (1.4404 / 316L) which offers robust mechanical strength and resistance against harsh chemicals including acidic and alkaline cleaning agents, making it well-suited for demanding environments such as the food and beverage, pharmaceutical, and automotive industries.

The sensor is equipped with an M12 male connector and is available with a 2 meter cable variant, allowing for straightforward electrical integration and flexible installation options. Its M18 threaded design ensures easy, fast, and space-efficient mounting. The sensor’s NPN output type and IP67 rating guarantee reliable operation in harsh ambient conditions with protection against dust and water ingress.

With a fast response time of 0.5 milliseconds, it enables efficient object detection and reduces false detections, thereby increasing operational throughput. The sensor operates within a temperature range of -25°C to 55°C and supports a maximum DC voltage of 30 V at a maximum current of 30 mA. It is CE certified and cULus listed, confirming its compliance with international safety standards.

This photoelectric sensor is ideal for applications in consumer goods manufacturing, food processing lines including breweries and dairies, pharmaceutical production, mechanical construction, automotive manufacturing, building automation, and other industrial uses. The stainless steel front screen is only 3 mm thick and chemically resistant, offering a long service life and reduced maintenance requirements.
