Photoelectric sensors play a crucial role in modern industrial automation, offering non-contact detection capabilities for various applications. The GRTE18S-N2412V represents a specific model within this category, designed to meet demanding operational requirements. This guide explores the technical specifications, working principles, installation considerations, and typical use cases for this sensor, providing practical information for engineers and technicians.
The GRTE18S-N2412V is typically a diffuse reflective photoelectric sensor operating on a 24V DC power supply. It utilizes a modulated infrared light source to detect objects within its sensing range. The "N" in its model number often indicates a normally open output configuration, while "2412" specifies the voltage rating. These sensors convert light signals into electrical outputs, triggering responses in connected control systems when an object interrupts or reflects the light beam.
Key technical parameters include sensing distance, response time, output type, and environmental ratings. The exact sensing distance varies by model variant but generally falls within 0-2 meters for diffuse reflective types. Response times are typically in the millisecond range, enabling high-speed detection. The output is usually a transistor-based switch (PNP or NPN) compatible with PLCs and other controllers. Many industrial photoelectric sensors feature IP67 protection, making them resistant to dust and water ingress—a critical factor for the GRTE18S-N2412V in harsh environments.
Installation requires attention to mounting position, alignment, and environmental factors. Proper mounting ensures consistent detection and avoids false triggers. Factors like background objects, material color, surface texture, and ambient light can affect performance. For instance, shiny or dark objects may reflect light differently, requiring sensitivity adjustment. The sensor's housing often includes mounting brackets or threaded barrels for easy integration into machinery. Electrical connections follow standard color codes: brown for positive, blue for negative, and black for output signal.
Application areas for the GRTE18S-N2412V span multiple industries. In packaging lines, it detects product presence on conveyors. In automotive assembly, it verifies component placement. Material handling systems use such sensors for position sensing and counting. The 24V DC operation makes it compatible with most industrial control voltages, while its compact design allows installation in space-constrained locations.
Maintenance involves periodic lens cleaning to prevent dust accumulation, which can reduce sensitivity. Diagnostic LEDs often indicate power status and output activation, aiding troubleshooting. Common issues include misalignment, dirty lenses, or electrical interference—addressed through systematic checks of mounting, cleanliness, and wiring.
Compared to other sensor types like inductive or capacitive, photoelectric sensors offer advantages in detecting non-metallic objects and providing longer ranges. However, they may be affected by transparent materials or environmental contaminants. The GRTE18S-N2412V balances these factors with robust construction and reliable performance.
When selecting a photoelectric sensor, consider object properties, required sensing distance, environmental conditions, and output needs. The GRTE18S-N2412V suits applications needing moderate-range detection of solid objects. For precise requirements, consult manufacturer datasheets detailing exact specifications for this model variant.
In summary, the GRTE18S-N2412V photoelectric sensor provides a versatile solution for object detection in industrial settings. Its design emphasizes reliability under typical operating conditions, contributing to automated system efficiency. Proper selection, installation, and maintenance ensure optimal performance across its service life.
