SICK GRSE18S-N1136 Long-Range Through-Beam Sensor

SICK GRSE18S-N1136 Through-Beam Photoelectric Sensor – Long-Range, High-Precision Detection

The SICK GRSE18S-N1136 through-beam photoelectric sensor is designed for applications requiring dependable detection over long distances, delivering a working range of up to 15 meters. Its focused red LED emission creates a bright and easily visible spot, helping installers achieve precise alignment with minimal effort. The compact M18 cylindrical housing and sealed IP67 construction ensure stable operation even in challenging factory environments. This model is ideal for solving issues where inconsistent detection, long sensing distances, or fast-moving targets create difficulties in production lines. With its straightforward design and no adjustment requirements, it is ready for rapid installation and reliable, repeatable performance.

The GRSE18S-N1136 provides fast, accurate switching with a response time well under a millisecond, making it suitable for high-speed processes where timing is critical. Its complementary NPN output supports integration with a wide range of control systems, while two clear LED indicators assist technicians during setup and operation by showing power and detection status at a glance. Built with a durable ABS housing and robust optical components, the sensor maintains consistent operation despite vibration, dust, or changing temperatures. Its wide DC supply range and built-in protection circuits contribute to long service life, offering a dependable detection solution without the need for complex configuration.

Why GRSE18S-N1136?

The GRSE18S-N1136 stands out because it delivers long-range, high-accuracy detection in a compact M18 design that installs effortlessly. Its sharply defined red light spot makes alignment simple, while its rugged IP67 housing keeps performance consistent even in harsh production areas. It’s a sensor built for speed, reliability, and minimal maintenance—perfect for demanding automation tasks.

What Problem Does It Solve?

This model eliminates unreliable detection over long distances, a common issue in fast-moving or space-constrained applications. It overcomes false triggers caused by vibration, dust, or inconsistent lighting by using a powerful through-beam design that maintains signal clarity. When production lines need dependable, repeatable detection without constant adjustment, the GRSE18S-N1136 is the ideal solution.

The Applications for the GRSE18S-N1136

1. High-Speed Conveyor Item Detection

In fast-moving conveyor systems, products can pass by in rapid succession, making consistent detection difficult. The GRSE18S-N1136 excels here because its long optical reach and concentrated red beam allow it to identify objects cleanly even when spacing is tight or motion is erratic. The through-beam design ensures that background surfaces, color differences, or changing ambient light do not influence the reading. This creates reliable triggering for counting, sorting, and routing tasks. Even when conveyors vibrate or carry mixed product types, the sensor maintains stable performance, helping production lines operate smoothly without constant manual tuning or recalibration.

2. Transparent Bottle Verification on Filling Machines

Many filling processes depend on confirming that a container is in position before liquid dispensing begins. Transparent or reflective bottles can confuse weaker sensing methods, but the GRSE18S-N1136’s strong optical signal penetrates these materials effectively. Its quick switching response ensures the filling cycle starts only when a container is truly present, lowering the risk of spills or wasted product. Moisture, cleaning sprays, and machine vibration do not easily disrupt the beam, allowing for dependable operation throughout the workday. This makes the sensor particularly effective for beverage and chemical production lines where clarity or shape variations often introduce detection challenges.

3. Carton Position Feedback in Robotic Palletizing

Robotic palletizers need accurate confirmation of carton positions before performing lifts or placements. Dust, diverse packaging textures, and wide working areas often interfere with detection. The GRSE18S-N1136 counters these issues through a stable long-distance beam that provides precise feedback even across several meters of operating space. Its rapid response ensures the robot receives timely status updates, avoiding misplaced stacks or dropped items. The robust housing allows it to function reliably in environments where cardboard fibers, debris, or continuous motion are present. By improving positional certainty, the sensor helps reduce rework and enhances the speed and safety of palletizing operations.

4. Industrial Gate and Vehicle Access Monitoring

Facilities that manage frequent vehicle movement—such as forklifts, warehouse shuttles, or delivery trucks—require dependable sensors to trigger gates or safety interlocks. The GRSE18S-N1136 provides a clear interruption signal whenever a vehicle crosses its beam, regardless of lighting reflections or large metal surfaces. Its extended sensing range ensures early detection, allowing automated doors or barriers to react smoothly. Temperature shifts, dust, and outdoor exposure do not significantly impact performance thanks to the rugged enclosure. This reliable operation helps maintain safe traffic flow, reduces accidental barrier impacts, and supports efficient entry control in busy industrial yards or loading zones.
