SICK Background Suppression Photoelectric Sensor Cylindrical 3 mm to 300 mm PNP IP67/IP68/IP69K Stainless Steel GRTB18-P2412V

SICK GRTB18-P2412V Background Suppression Photoelectric Sensor delivers advanced object detection using background suppression technology, making it ideal for industrial environments where precise and reliable sensing is critical. The cylindrical sensor is equipped with a stainless steel V4A housing, providing excellent resistance to chemical cleaning agents and mechanical wear. With its detection range of 3 mm to 300 mm, the sensor is suitable for various applications including conveyor presence detection, object sorting, and machine vision pre-trigger systems.

Configured for background suppression, the sensor ensures stable detection even in complex environments with reflective backgrounds. The PNP output type allows for flexible integration with PLCs and automated control circuits.

Rated IP67, IP68, and IP69K, the sensor withstands washdowns, immersion, and high-pressure cleaning, supporting hygienic operations in food processing and pharmaceutical plants. Threaded mounting combined with dual stainless steel fastening nuts simplifies installation and improves mechanical stability.

Pin point LED light source ensures visible and accurate alignment during setup. Fast 500 µs response time enhances performance in high-speed sorting and packaging lines. Wide operating temperature range from -25°C to +55°C enables deployment in warm process environments.

Reverse-polarity, short-circuit, and overcurrent protections preserve sensor and control circuit integrity.

The GR18 Inox series leverages SICK’s renowned expertise in industrial sensor design for demanding applications. Suitable for use in presence detection, quality assurance, and level sensing of stacked pallets or containers. Its easy-to-adjust sensing range, via an on-device potentiometer, allows rapid configuration and adaptation to different tasks.

A green LED indicates power status, while a yellow LED signals object detection. Connections are made via a straight male M12, 4-pin connector, ensuring compatibility with common sensor cabling standards.

Hygienic and washdown machinery requiring frequent cleaning benefit from the robust build and multiple IP certifications. This sensor is not certified for hazardous zones, but meets CE and UL standards for general industrial use.
