The SICK GRL18S-N2431V (part number 1085715) is a high-performance retro-reflective photoelectric sensor designed to deliver reliable long-distance object detection in demanding industrial applications. As part of the GR18S series, this sensor combines advanced optical technology with a robust cylindrical housing to ensure consistent performance under challenging conditions.

One of the key strengths of the GRL18S-N2431V is its ultra-long sensing range, capable of detecting objects from 30 mm up to 7.2 m when used with a suitable reflector. This extensive detection range makes it ideal for applications such as automated conveyor systems, material handling, packaging lines, and warehouse logistics. The retro-reflective detection principle ensures stable performance even with objects that have reflective, dark, or irregular surfaces, providing accurate detection in diverse operational scenarios.

For installation and operational convenience, the sensor is equipped with a dual-lens system that allows for a minimum distance to the reflector. This feature ensures reliable detection even at close range, enhancing the sensor’s versatility in various applications.

The GRL18S-N2431V features a PinPoint visible red LED emitter with a wavelength of 650 nm, providing a focused, clearly visible light spot for precise alignment. This focused light spot simplifies installation and alignment, while the integrated signal strength indicator provides immediate visual feedback, allowing operators to position the sensor accurately and optimize detection performance with minimal effort.

The sensor is housed in a rugged M18 cylindrical body with IP67 protection, offering complete protection against dust, water jets, and high-pressure washdowns. Its durable construction ensures consistent performance in demanding industrial settings, including manufacturing floors, food processing areas, and outdoor environments exposed to the elements. The compact cylindrical form factor also allows easy installation in tight spaces or standard mounts.

In terms of electrical specifications, the GRL18S-N2431V operates within a supply voltage range of 10 V DC to 30 V DC and features an NPN switching output. It supports light/dark switching modes, providing flexibility for various control systems. The sensor’s response time is less than 500 ¬¨¬µs, enabling it to keep pace with high-speed production lines and automated machinery.

In summary, the GRL18S-N2431V offers a combination of long-range detection, precise LED alignment, dual-lens flexibility, and rugged industrial durability. It is an excellent choice for engineers and automation professionals seeking a dependable sensor for high-performance applications in logistics, packaging, material handling, and robotic systems.
