Photoelectric sensors are essential components in modern industrial automation, offering non-contact detection capabilities for various applications. The GRSE18S-N1121V photoelectric sensor represents a reliable solution for object detection, positioning, and counting tasks across multiple industries. This through-beam type sensor operates by emitting an infrared light beam from the transmitter to the receiver, detecting interruptions in the beam path with high precision.
The GRSE18S-N1121V features an 18mm diameter cylindrical housing constructed from nickel-plated brass, providing durability in challenging industrial environments. With IP67 protection rating, this sensor withstands dust exposure and temporary immersion in water, making it suitable for manufacturing floors, packaging lines, and outdoor installations. The device operates on a 10-30V DC power supply and delivers both NPN and PNP output configurations through its 4-pin M12 connector, offering compatibility with various control systems including PLCs and relay modules.
Technical specifications reveal a sensing distance of 15 meters between transmitter and receiver units, with response time under 1 millisecond. The stable detection performance remains consistent regardless of object surface characteristics, detecting transparent materials like glass or plastic with equal reliability as opaque objects. Built-in sensitivity adjustment allows operators to fine-tune detection parameters for specific applications, while the red LED indicator provides clear operational status at a glance.
Industrial applications span multiple sectors including automotive manufacturing, where the sensor monitors component presence on assembly lines. In packaging facilities, GRSE18S-N1121V sensors count products moving on conveyor belts and verify package sealing. Material handling systems utilize these sensors for pallet positioning and inventory management, while automated storage systems depend on them for item tracking and retrieval operations. The food processing industry benefits from their hygienic non-contact design for container detection on filling lines.
Installation requires proper alignment between transmitter and receiver units, typically mounted on opposite sides of the detection area. Maintenance involves periodic lens cleaning to prevent dust accumulation that could affect performance. Environmental considerations include operating temperature range from -25°C to +55°C, with resistance to vibration and electrical noise common in industrial settings. Compared to proximity sensors, photoelectric variants like GRSE18S-N1121V offer longer detection ranges and ability to sense non-metallic objects, though they may require more precise alignment.
Future developments in sensor technology continue to enhance performance characteristics, but the fundamental reliability of through-beam photoelectric sensors ensures their ongoing relevance in industrial automation. The GRSE18S-N1121V maintains its position as a versatile detection solution through robust construction, consistent performance, and broad compatibility with industrial control architectures. Proper selection involves considering detection distance, environmental conditions, and output requirements to ensure optimal system integration.
