The RL31-8-H-800-RT/73c/136 photoelectric switch represents a sophisticated component in industrial automation, designed for precise object detection across various applications. This device operates on the principle of light beam interruption or reflection to identify the presence, absence, or position of objects. With a sensing range of up to 800 meters, it is particularly suited for long-distance detection in harsh environments, such as manufacturing lines, material handling systems, and outdoor installations.
Constructed with a rugged housing, the RL31-8-H-800-RT/73c/136 ensures durability against dust, moisture, and mechanical impacts, meeting IP67 protection standards. The "RT" suffix indicates a retro-reflective model, which uses a reflector to bounce light back to the sensor, enabling reliable detection even in low-visibility conditions. The "73c" and "136" codes refer to specific electrical configurations and output types, typically including NPN or PNP transistor outputs for seamless integration with PLCs (Programmable Logic Controllers) and other control systems.
Key features of this photoelectric switch include high immunity to ambient light interference, thanks to modulated infrared LED technology. This allows stable performance under varying lighting conditions, from bright sunlight to complete darkness. The device also offers adjustable sensitivity, enabling users to fine-tune detection thresholds to avoid false triggers from background objects or environmental factors. Installation is straightforward, with mounting brackets and alignment indicators provided for quick setup.
In practical use, the RL31-8-H-800-RT/73c/136 excels in applications like conveyor belt monitoring, where it detects items for sorting or counting, and in safety systems, where it acts as a barrier to prevent machinery accidents. Its long-range capability makes it ideal for large-scale operations, such as warehouse automation and agricultural equipment, where traditional sensors may fall short. Maintenance is minimal, with self-diagnostic functions alerting users to issues like lens contamination or alignment shifts.
When selecting a photoelectric switch, factors like response time, beam type, and environmental resistance are critical. The RL31-8-H-800-RT/73c/136 addresses these with a fast response time of under 1 millisecond, ensuring real-time detection for high-speed processes. Compared to ultrasonic or inductive sensors, it offers non-contact operation without wear, reducing long-term costs. Users should verify compatibility with their voltage supply (commonly 10-30V DC) and load requirements to optimize performance.
Overall, the RL31-8-H-800-RT/73c/136 photoelectric switch is a versatile and reliable solution for industrial sensing needs. Its combination of long range, robust design, and advanced features supports efficient automation, contributing to improved productivity and safety in diverse sectors. For specific technical details, always refer to the manufacturer's datasheet to ensure proper application and compliance with industry standards.
