The GLV18-8-200/59/102/115 is a compact, high-performance photoelectric switch characterized by its robust construction and advanced sensing capabilities. Typically, such switches operate based on the modulation of light beams—either through through-beam, retro-reflective, or diffuse reflection methods—to detect objects without physical contact. The numerical designation "GLV18-8-200/59/102/115" often corresponds to specific technical parameters: for instance, "18" may refer to the housing diameter in millimeters, "8" could indicate the sensing distance in meters, and "200/59/102/115" might denote voltage ratings, output configurations, or environmental tolerances. However, exact interpretations can vary by manufacturer, so consulting the official datasheet is essential for accurate application.
Key features of the GLV18-8-200/59/102/115 model include a durable housing resistant to dust, moisture, and mechanical shocks, making it suitable for harsh industrial environments like manufacturing plants, packaging lines, and material handling systems. Its sensing range is optimized for medium to long-distance detection, often up to several meters, with high repeat accuracy and fast response times. The switch typically supports various output types, such as NPN or PNP transistor outputs, and may integrate LED indicators for status monitoring. Additionally, it operates across a wide voltage range, ensuring compatibility with different control systems, from 12V DC to 240V AC setups.
In practice, the GLV18-8-200/59/102/115 photoelectric switch excels in scenarios requiring non-contact detection. For example, in conveyor belt systems, it can count products, monitor positioning, or trigger automated actions when an object passes its beam. In automotive assembly lines, it ensures precise part placement by detecting components without interference. The switch's immunity to ambient light and electromagnetic interference enhances reliability, reducing false triggers in noisy environments. Maintenance is straightforward, with periodic lens cleaning and voltage checks recommended to sustain optimal performance.
When selecting a photoelectric switch like the GLV18-8-200/59/102/115, consider factors such as the detection method, sensing distance, environmental conditions, and electrical requirements. Through-beam variants offer the longest range and highest accuracy but require separate emitter and receiver units. Retro-reflective models use a reflector for easier installation, while diffuse reflection types are ideal for close-range detection of varied surfaces. Always verify the switch's IP rating for protection against ingress and its temperature range to ensure durability in specific settings.
In summary, the GLV18-8-200/59/102/115 photoelectric switch represents a versatile tool for automation, combining precision, durability, and adaptability. By understanding its technical nuances and aligning them with application needs, users can enhance system efficiency and reduce downtime.
