The OBT200-18GM60-E5 represents a significant advancement in industrial sensing technology, offering reliable performance in diverse automation environments. As a photoelectric switch, it utilizes modulated infrared light to detect objects without physical contact, making it ideal for applications where precision and durability are paramount. This device operates on the through-beam principle, where a separate emitter and receiver are aligned. When an object interrupts the light beam between them, the switch triggers an output signal. The OBT200-18GM60-E5 features an 18mm threaded barrel housing constructed from nickel-plated brass, providing robust resistance to mechanical stress and environmental factors such as dust, moisture, and oil splashes. Its IP67 protection rating ensures reliable operation in harsh conditions, common in manufacturing, packaging, and material handling industries.
One of the key specifications of the OBT200-18GM60-E5 is its sensing range of up to 60 meters, which allows for flexible installation in large-scale setups. The switch supports both light-on and dark-on operating modes, enabling customization based on specific control logic requirements. It incorporates a built-in potentiometer for sensitivity adjustment, allowing users to fine-tune detection thresholds to avoid false triggers from ambient light or background interference. The device operates on a 10-30V DC supply voltage and provides a complementary NPN output, ensuring compatibility with a wide range of programmable logic controllers (PLCs) and industrial automation systems. A red LED indicator simplifies commissioning and diagnostics by providing visual feedback on the switch's status.
In practical applications, the OBT200-18GM60-E5 excels in scenarios requiring long-range object detection. For instance, in conveyor belt systems, it can monitor the presence or absence of items, triggering sorting mechanisms or stopping the belt to prevent jams. In automated storage and retrieval systems, it ensures precise positioning of pallets or containers by detecting reflective markers. The switch's high switching frequency of up to 1kHz makes it suitable for high-speed counting tasks, such as monitoring production lines where components move rapidly. Additionally, its resistance to vibration and temperature fluctuations from -25°C to 55°C allows deployment in outdoor settings or unheated warehouses.
Installation and maintenance of the OBT200-18GM60-E5 are straightforward due to its standardized design. The 18mm diameter enables easy mounting using standard nuts, while the integrated cable or connector options (depending on the variant) simplify wiring. To optimize performance, it is recommended to align the emitter and receiver accurately, ensuring the light beam is perpendicular to the target path. Regular cleaning of the lenses prevents accumulation of dirt or debris that could attenuate the signal. Users should also verify the electrical connections periodically to avoid voltage drops or loose contacts that might affect reliability.
Compared to other sensing technologies like inductive or capacitive proximity switches, the OBT200-18GM60-E5 offers distinct advantages for non-metallic object detection. Its ability to sense transparent or colored materials—such as glass bottles or plastic wrappers—makes it versatile in industries like food and beverage or pharmaceuticals. However, in environments with heavy fog or steam, supplementary shielding or alternative sensor types may be necessary to maintain accuracy. The switch complies with international standards including CE and RoHS, ensuring safety and environmental compatibility.
Looking ahead, the integration of smart features such as IO-Link communication could enhance the OBT200-18GM60-E5's capabilities, enabling real-time diagnostics and parameter adjustments via network interfaces. For now, its proven track record in reliability and precision continues to make it a preferred choice for engineers seeking cost-effective automation solutions. By understanding its specifications and best practices for deployment, users can maximize efficiency and reduce downtime in their operations.
