The SICK 1059536 (GRL18S-P1338) is a reliable retro-reflective photoelectric sensor designed to deliver precise and efficient object detection in industrial automation settings. Belonging to the GR18 series, it combines a compact cylindrical design with advanced optical performance, making it an ideal choice for applications in logistics, packaging, material handling, and manufacturing.

At the heart of the sensor is a dual-lens retro-reflective system, enabling dependable detection from as close as 30 mm to as far as 7.2 m. This extended operating distance ensures flexibility across different automation processes, whether detecting objects at short range for presence verification or monitoring long distances on conveyors. The dual-lens technology enhances stability and reduces the risk of false detections, even in environments with varying ambient light.

The GRL18S-P1338 uses a visible red PinPoint LED emitter operating at 650 nm. The beam produces a well-defined, concentrated spot, allowing quick and accurate sensor alignment during setup. With a spot size of around 175 mm at 7 m, it ensures consistent performance when detecting small or large targets, providing high accuracy even under challenging conditions.

Performance is another key advantage of this model. The sensor features a PNP light-switching output, which means the output is activated when the beam detects the presence of an object. With a maximum load of 100 mA, a rapid response time of less than 500 µs, and a switching frequency of up to 1,000 Hz, the GRL18S-P1338 is well suited for high-speed applications. This makes it particularly effective for sorting, counting, and object tracking in fast-moving production lines.

In addition to its strong sensing performance, the sensor is engineered for durability and ease of installation. Its M18-threaded ABS housing measures just 18 √ó 18 √ó 38.1 mm, providing a compact profile that fits easily into restricted spaces. Rated to IP67, it withstands dust and water ingress, ensuring reliable operation in demanding industrial environments. Supplied with a 2 m PVC cable and mounting nuts, it integrates quickly into new or existing systems.

The device also features clear visual indicators: a green LED to confirm power status and a yellow LED to show the switching state. These indicators simplify alignment and troubleshooting, reducing downtime during setup and maintenance.

Overall, the SICK GRL18S-P1338 delivers a blend of long sensing range, pinpoint accuracy, high switching speed, and rugged housing. It is a versatile and dependable sensor for engineers seeking reliable performance in compact industrial automation solutions
