In the intricate world of industrial automation, where precision and reliability are non-negotiable, the choice of sensing technology can dictate the efficiency of an entire production line. Among the myriad of components, photoelectric switches stand as silent sentinels, ensuring seamless operations. The OBE2000-R3-E2-0.2M-V31 photoelectric switch emerges as a standout performer in this critical category, engineered to meet the rigorous demands of modern manufacturing and process control environments.
The OBE2000-R3-E2-0.2M-V31 is a through-beam photoelectric sensor, a design known for its superior detection range and high immunity to environmental interference. The "0.2M" in its designation specifies a 0.2-meter sensing distance, making it ideal for applications requiring accurate object detection within a compact space. Its core functionality is based on a modulated infrared LED light source and a separate receiver. The transmitter projects a focused beam of light to the receiver unit. When an object interrupts this beam, the receiver triggers a switching signal. This fundamental principle allows for highly reliable detection of virtually any material, regardless of color, surface texture, or reflectivity.
What sets the OBE2000-R3-E2-0.2M-V31 apart is its robust construction and advanced features tailored for industrial durability. The housing is typically built from high-grade, reinforced plastic or metal, offering significant resistance to dust, moisture, and mechanical impact, aligning with IP67 protection standards. This ensures consistent performance in challenging conditions, from packaging lines to woodworking machinery. The "V31" suffix often relates to specific electrical characteristics, such as a voltage range and output configuration (like NPN or PNP transistor output), providing compatibility with a wide array of PLCs (Programmable Logic Controllers) and control systems.
The application scope for this sensor is vast. It is indispensable in material handling for detecting the presence or absence of boxes on a conveyor, ensuring proper spacing and preventing jams. In automated assembly, it verifies if components are correctly positioned before a robotic arm engages. It serves as a critical safety interlock in machinery, preventing operation when guards are open. Furthermore, its through-beam design makes it perfect for counting tasks, where high-speed and error-free detection of small items is paramount. The precise 0.2-meter range is particularly useful in confined robotic cells or on compact machinery where space optimization is crucial.
Installation and alignment of the OBE2000-R3-E2-0.2M-V31 are straightforward, thanks to its clear optical axis indicators. However, for through-beam sensors, precise alignment of the transmitter and receiver is essential for optimal function. Many models feature alignment LEDs that provide visual confirmation of beam reception, drastically reducing setup time and potential errors. Maintenance is minimal, primarily involving periodic lens cleaning to ensure the infrared beam is not attenuated by accumulated dirt or grime.
When selecting a photoelectric switch, engineers must consider factors like sensing distance, response time, environmental robustness, and output type. The OBE2000-R3-E2-0.2M-V31 addresses these needs with a balanced and specialized specification sheet. Its defined 0.2-meter range offers a focused solution, eliminating the uncertainty and potential interference issues that can come with overly long-range sensors in tight spaces. Its fast response time ensures it can keep pace with high-cycle production lines without missing a detection event.
In conclusion, the OBE2000-R3-E2-0.2M-V31 photoelectric switch represents a focused tool for precision industrial sensing. It is not a generic sensor but a specific solution designed for applications where reliable beam-breaking detection at a short, defined distance is required. By offering durability, environmental resistance, and easy integration, it enhances system reliability, reduces downtime, and contributes to the smooth, automated flow of modern industry. For system integrators and maintenance engineers seeking a dependable through-beam sensor for precise object detection, the OBE2000-R3-E2-0.2M-V31 stands as a proven and effective component.
