SICK Background Suppression Photoelectric Sensor Barrel Style 20 mm to 150 mm Detection Range PNP Output IP67 GRTB18S-P2412V

The SICK GRTB18S-P2412V Background Suppression Photoelectric Sensor is a barrel-style cylindrical sensor designed for challenging industrial detection tasks requiring hygienic wash-down capabilities and operation under harsh conditions.

Operating over a voltage range of 10V to 30V DC, it provides a reliable PNP output signal suitable for seamless integration with common control systems.

This sensor offers a detection range adjustable from 20 mm up to 150 mm, utilizing a visible red LED light source to distinctly identify objects against complex backgrounds, optimizing detection accuracy.

Constructed with a stainless steel housing, it resists corrosion and mechanical wear, making it ideal for application in food and beverage industries, automated sorting lines, and conveyor monitoring systems where fast switching and compact mounting are essential.

The device supports high-speed detection thanks to its rapid 0.5 ms response time, while rated ingress protections IP67, IP68, and IP69K ensure resilience against dust, water jetting, and high-temperature wash-downs.

Installation is facilitated by an M18 x 1 threaded mount, complete with two fastening nuts, and connection is made through a robust 4-pin male M12 connector. Operators benefit from multiple LED indicators - a green LED for power and a yellow LED signaling the presence of an object via received light status.

The sensing range can be finely tuned using a 270° potentiometer, allowing precise adjustments based on the target's reflectance. Enables high-speed object detection with a fast 0.5 ms response time. Equipped with PNP output for easy integration with switching controls.

Operates reliably in temperatures from -25 °C to 55 °C. Stainless steel housing provides excellent corrosion resistance in harsh industrial environments. Rated for wash-down and immersion resistance with IP67, IP68, and IP69K certifications.

Uses a visible red LED light source for effective background suppression detection. Features threaded mounting with M18 x 1 thread and includes two fastening nuts for secure installation. Connects via a 4-pin male M12 connector for secure and straightforward wiring.

Visual feedback via multiple LEDs indicates power status and object detection.

This sensor is widely used for automated sorting requiring background suppression, hygienic food and beverage washing processes, conveyor object presence monitoring, and machinery with compact threaded mounting needs.
