The SICK GRL18-N1131V (part number 1085965) is a high-performance retro-reflective photoelectric sensor engineered for precise and reliable object detection in medium-range industrial automation applications. Part of the GRL18 series, this sensor combines advanced optical technology with a durable M18 cylindrical housing, ensuring consistent and accurate performance across a variety of industrial environments.

A key feature of the GRL18-N1131V is its medium-range sensing capability, capable of detecting objects from 50 mm up to 6 m when used with an appropriate reflector. This makes it ideal for applications such as conveyor monitoring, automated packaging lines, material handling, and robotic automation. The retro-reflective detection principle provides stable and dependable sensing even when detecting dark, reflective, or irregularly shaped objects, ensuring reliable operation in challenging industrial conditions.

The sensor incorporates a PinPoint visible red LED emitter with a wavelength of 650 nm, producing a sharply focused and highly visible light spot for precise alignment. This feature simplifies installation, allowing operators to position the sensor accurately while quickly verifying proper alignment. The visible LED ensures consistent detection performance across the sensor’s full range, reducing setup time and minimizing potential errors.

Electrically, the GRL18-N1131V features dual NPN outputs with configurable light-on and dark-on switching modes, enabling flexible integration into a wide variety of control systems. The dual-output design allows engineers to adapt detection logic to specific application requirements. Built-in protective measures, including reverse polarity, short-circuit, and overload protection, ensure long-term reliable operation in industrial environments.

Mechanically, the sensor is housed in a robust M18 cylindrical body with an IP67 rating, providing protection against dust, water ingress, and mechanical impacts. Its rugged construction guarantees stable performance in harsh industrial settings such as factory floors, robotic automation systems, and automated packaging lines. The compact M18 form factor allows installation in tight spaces without compromising durability or functionality.

Performance-wise, the GRL18-N1131V delivers a fast response time, making it suitable for high-speed production lines and automated machinery where rapid and precise detection is critical. Its wide operating voltage range and low power consumption allow seamless integration into industrial control systems while maintaining consistent and dependable operation over time.

In summary, the GRL18-N1131V combines medium-range detection, precise LED alignment, dual-output flexibility, and rugged industrial durability, making it an excellent choice for engineers and automation professionals seeking high-performance sensing for material handling, packaging, and automated manufacturing applications.
