In the demanding world of industrial automation, the reliability and accuracy of sensing components are non-negotiable. The RLK31-8-2500-IR/31/115 photoelectric switch stands out as a premier choice for engineers and system integrators seeking unwavering performance in diverse and challenging environments. This device exemplifies the pinnacle of German engineering, designed to deliver consistent, long-range detection where other sensors might falter.
At its core, the RLK31-8-2500-IR/31/115 is a through-beam photoelectric sensor. This model utilizes an infrared light beam with a wavelength of 880 nm, ensuring superior immunity to ambient light interference from factory lighting or sunlight. The "2500" in its designation is a key feature: it offers an exceptional sensing range of up to 25 meters. This makes it ideal for applications requiring detection across wide conveyors, large warehouse aisles, or extensive material handling systems. The robust housing, rated at IP67, provides complete protection against dust ingress and temporary immersion in water, guaranteeing operation in harsh conditions found in woodworking, automotive, or packaging industries.
The technical specifications of this sensor are tailored for precision. It operates on a 10-30V DC supply, making it compatible with standard industrial control voltages. The output is a solid-state NPN normally-open configuration, providing a reliable switching signal to PLCs, counters, or safety relays. Its high switching frequency allows it to keep pace with fast-moving production lines without missing a beat. A critical advantage is its precise optical alignment, facilitated by a clear signal strength indicator, which drastically reduces installation and commissioning time.
Real-world applications for the RLK31-8-2500-IR/31/115 are vast. In logistics, it is deployed for pallet detection on high-bay storage systems and for controlling the gap between containers on conveyor lines. In the automotive sector, it ensures precise positioning of vehicle bodies on assembly lines. Within the paper and printing industries, it reliably detects the edge of large material rolls or monitors web breaks over long distances. Its through-beam design offers the highest level of reliability for object detection because the receiver only sees the light from the opposed emitter, making it less susceptible to false triggers from reflective or glossy target surfaces.
Choosing the RLK31-8-2500-IR/31/115 translates to tangible operational benefits. Its extended range reduces the number of sensors needed for a given area, lowering overall system cost and complexity. The durability inherent in its design minimizes unplanned downtime and maintenance costs, contributing to a higher overall equipment effectiveness (OEE). For system designers, its standardized mounting options and clear documentation simplify integration into both new and existing automation frameworks.
When selecting a photoelectric switch for critical detection tasks, the decision often comes down to proven performance under stress. The RLK31-8-2500-IR/31/115 has established a reputation for delivering exactly that. Its combination of long-range capability, environmental resilience, and precise electrical output makes it more than just a component; it is a foundational element for building reliable and efficient automated systems. For projects where detection failure is not an option, this sensor provides the confidence and data integrity that modern industry demands.
