SICK GRTE18-N2447 Photoelectric Sensor – M18 Red Light

The Applications of the SICK GRTE18-N2447

1. Fast Conveyor Presence Detection in Warehouses

In busy warehouse conveyor systems, items of mixed colors and surface textures move quickly toward sorting or labeling stations. The GRTE18-N2447 performs well in this environment because its concentrated red-light beam stays stable even when packages have reflective tape, dark printing, or uneven surfaces. Mounted at key checkpoints, it confirms that each item is correctly positioned before the next machine action occurs. Its rapid response time reduces the chance of missed reads when conveyors run at high speed. With adjustable sensitivity, technicians can fine-tune the sensor to ignore light reflections from rollers or metal guards, keeping the flow uninterrupted.

2. Small-Part Detection in Precision Assembly Lines

Compact assembly fixtures used in electronics, automotive parts, or mechanical subassemblies often require reliable detection of tiny components. The GRTE18-N2447 helps address this by producing a focused light spot that easily identifies the presence of small, low-profile parts. Its M18 cylindrical body allows integration into tight jigs without compromising alignment. When used for assembly verification, it ensures a component is present before operators or automated tools proceed to the next step. This reduces assembly errors, lowers rework, and helps maintain a consistent production rhythm, even when handling items with varying surface finishes or shapes.

3. Packaging Machine Material Alignment

Packaging equipment such as pouch formers, wrapping systems, and carton folders depends on accurate position sensing to avoid material jams. The GRTE18-N2447 is effective here because it can detect diverse packaging materials—from glossy laminated films to matte cardboard—without requiring constant recalibration. Its high switching frequency provides timely feedback when a material edge is misaligned or when a fold is not fully formed. Maintenance teams can quickly adjust the sensing range using the built-in potentiometer, allowing the sensor to distinguish between intentional material movement and unwanted slack or flutter, ultimately reducing stoppages and improving production stability.

4. Object Confirmation for Robotic Pick Stations

Robotic picking cells often need a fast, dependable way to verify whether a part is present before a gripper engages. The GRTE18-N2447 offers this reliability with its precise axial beam that isolates the target area from background clutter. Because of its quick reaction time, the robot can maintain high cycle rates without waiting for delayed confirmation signals. The sensor can be positioned close to trays, nests, or feeder chutes thanks to its compact design, making it suitable for dense workstation layouts. Its resistance to dust and splashes ensures performance remains consistent, even in manufacturing zones with frequent tool activity or coolant mist.
