Product Description

SICK GRL18-N1137 Photoelectric Retro-Reflective Sensor – Long-Range, Stable Detection

The SICK GRL18-N1137 photoelectric retro-reflective sensor is designed to deliver dependable object detection across long distances, making it well-suited for automated systems that rely on consistent presence monitoring. It uses a focused red PinPoint LED and a dual-lens arrangement to maintain stable detection performance even at close range. The M18 cylindrical housing provides mechanical strength while staying compact for tight installations. Clear LED indicators help operators identify operating status immediately, and the IP67 enclosure rating ensures resistance to dust and moisture. Offering a sensing range of up to 7.2 meters with compatible reflectors, the GRL18-N1137 is built for demanding industrial environments.

The GRL18-N1137 provides fast, consistent switching in high-speed production setups thanks to its rapid response time and complementary NPN output. Its sensitivity can be easily adjusted using the built-in potentiometer, allowing it to handle varying reflector sizes or challenging material surfaces. The bright optical spot improves alignment during installation, reducing setup time. Its rugged ABS construction and wide operating temperature range support long-term reliability on conveyors, packaging stations, and automated transport systems. Because the sensor maintains strong optical performance across extended distances, machine builders can reduce the number of sensing points required, ultimately lowering maintenance and integration costs.

Why SICK GRL18-N1137?

The SICK GRL18-N1137 stands out for its long-range performance, bright pinpoint LED, and reliable switching even in fast-moving industrial environments. Its compact M18 body fits almost anywhere, while its rugged build ensures stable operation for years. It delivers precise, repeatable detection that helps automate processes with confidence.

What Problem Does It Solve?

The GRL18-N1137 solves the challenge of detecting objects consistently across varying distances, surfaces, and lighting conditions. It eliminates false triggers caused by glossy materials, unstable reflections, and rapid motion. By offering fast response, strong optical power, and simple alignment, it keeps automated lines running smoothly with fewer stoppages and less need for manual intervention.

The Applications of the SICK GRL18-N1137

1. High-Speed Parcel Tracking on Conveyor Systems

Modern parcel-handling lines operate with constant movement and items of unpredictable shapes. The GRL18-N1137 helps maintain accuracy by projecting a bright, narrow red beam that remains stable even when packages have glossy tape or uneven surfaces. Its extended sensing range allows one sensor to cover wider conveyor gaps, reducing installation points. When parcels rush past the detection zone, the fast response time ensures each item is reliably registered without delay. By preventing missed detections or overlapping reads, the sensor helps avoid routing mistakes and keeps throughput steady during peak processing periods.

2. Position Confirmation for Automated Barriers and Sliding Gates

Access control systems need immediate, reliable confirmation of gate position to prevent accidental contact with vehicles or machinery. The GRL18-N1137 provides this stability thanks to its strong optical output and dependable switching performance across long distances. Its IP67-rated housing remains unaffected by dust or moisture, making it suitable for semi-outdoor industrial environments. The rapid switching response ensures gate controllers receive real-time status updates, allowing quick stopping actions if something interrupts the beam. By maintaining consistent alignment and performance throughout various lighting conditions, the sensor contributes to safer, more predictable gate operations.

3. Reflective Packaging and Label Verification in Production Lines

Packaging lines often use reflective labels, metallic foils, and glossy films that confuse conventional sensors. The GRL18-N1137 tackles these issues with its polarization filter, which discriminates between the reflector and unintended reflections from packaging materials. Its adjustable sensitivity allows fine-tuning to suit different label sizes or carton textures. As products move quickly toward labeling or sealing stations, the fast response time ensures that every item is evaluated consistently. This reduces the risk of unlabelled or improperly wrapped goods moving downstream, supporting quality assurance and minimizing rework.

4. Container Presence Detection in Bottling and Filling Machines

Filling systems rely on precise confirmation that each container is correctly positioned before dispensing begins. Clear, colored, or curved bottles can be challenging for ordinary sensors, especially under wet or steamy conditions. The GRL18-N1137 provides a bright, focused beam that maintains reliable detection despite transparency or condensation. Its high switching frequency ensures no container is skipped, even during rapid production cycles. The durable design withstands cleaning routines and fluctuating temperatures common in food and beverage environments. This contributes to smoother operations, fewer filling errors, and improved line efficiency.
