SICK GRTE18-N2442 Photoelectric Proximity Sensor with PinPoint LED Precision Detection
The SICK GRTE18-N2442 photoelectric proximity sensor is a compact M18 cylindrical sensor designed for accurate, non-contact object detection in automated industrial systems. Using an energetic photoelectric sensing principle combined with a focused PinPoint LED, it ensures stable detection of objects with different surface colors and reflectivity. Its adjustable sensing range and rugged metal housing address common challenges such as unreliable switching, limited mounting space, and harsh operating conditions. This makes the GRTE18-N2442 a dependable choice for packaging machinery, conveyor systems, and automated production equipment where consistent detection performance is critical.
The SICK GRTE18-N2442 provides precise and repeatable detection thanks to its concentrated red light spot, which improves target recognition on dark, glossy, or uneven surfaces. Sensitivity can be easily adjusted via an integrated potentiometer, allowing quick setup and fine control directly at the sensor. With fast response behavior, it supports high-speed operations without missed signals. The durable metal construction and high ingress protection rating ensure reliable operation in dusty, humid, or vibration-prone environments, helping manufacturers maintain process stability while reducing unplanned downtime.
Why SICK GRTE18-N2442?
The SICK GRTE18-N2442 is chosen when detection reliability must remain stable despite changing targets, tight installation spaces, and demanding industrial environments. Its focused PinPoint LED delivers a clearly defined sensing spot, enabling precise object recognition even on dark or low-reflectivity surfaces. The adjustable sensing range allows one sensor to adapt across multiple applications, reducing spare-part complexity. Combined with fast response time and a robust metal housing, it offers a balanced solution for engineers who value accuracy, durability, and long-term operational consistency.
What problem does it solve?
The SICK GRTE18-N2442 solves the common issue of inconsistent object detection caused by surface color variation, ambient light interference, or mechanical vibration. Traditional sensors often struggle with false switching or missed objects in fast-moving processes. This model provides stable detection through controlled light emission and fine sensitivity adjustment, ensuring reliable switching at high speeds. Its rugged construction also addresses premature sensor failure in dusty, humid, or high-temperature environments, helping production lines maintain uptime and predictable performance.

The Applications of the SICK GRTE18-N2442 Photoelectric Sensor
1. Consistent Carton Detection on High-Speed Conveyors
In conveyor-based logistics systems, products often vary in size, color, and surface texture, making reliable detection difficult. The SICK GRTE18-N2442 addresses this by using a focused light spot that detects carton edges without interference from surrounding conveyor structures. Its fast response supports high-speed movement without missed signals. The adjustable sensing range allows the same sensor to be used across different conveyor widths, while the rugged housing ensures stable operation in dusty distribution environments, helping maintain continuous and predictable material flow.
2. Small Component Presence Checking in Assembly Automation
Automated assembly processes rely on accurate confirmation that each component is correctly positioned before further operations. The GRTE18-N2442 is effective for detecting small or dark components that are typically difficult to sense. Fine sensitivity adjustment enables precise tuning for specific materials, reducing false negatives. Its compact cylindrical design fits easily near fixtures and tooling. This reliable presence verification helps prevent assembly errors, improves product quality, and reduces scrap caused by incomplete or incorrect builds.
3. Product Detection for Timing Control in Packaging Machines
Packaging and labeling equipment require precise detection to synchronize cutting, sealing, or labeling actions. The SICK GRTE18-N2442 delivers stable switching at high cycle rates, ensuring consistent timing even when products are closely spaced. The visible red light simplifies alignment during setup, shortening changeover times. Its durable construction withstands vibration and regular cleaning, supporting long-term reliability. This stability helps packaging lines operate at higher speeds while maintaining accuracy and minimizing unplanned stops.
4. Position Confirmation in Palletizing and End-of-Line Handling
End-of-line automation often depends on accurate confirmation of product or pallet position before robotic handling. The GRTE18-N2442 supports this by offering a long, adjustable sensing range and consistent detection across varied surface finishes. Controlled light emission reduces sensitivity to changing ambient lighting in warehouse settings. Its robust build ensures dependable performance under mechanical stress, contributing to safer robot movements and more reliable pallet stacking operations.
