The SICK GRL18-N2431V (part number 1085826) is a high-performance retro-reflective photoelectric sensor designed for precise and reliable object detection in medium- to long-range industrial automation applications. As part of the GRL18 series, it integrates advanced optical sensing technology with a robust M18 cylindrical housing, providing consistent and accurate performance across diverse industrial environments.

A standout feature of the GRL18-N2431V is its ultra-long sensing range, capable of detecting objects from 50 mm up to 16 m when used with a suitable reflector. This extended range makes it ideal for applications such as conveyor monitoring, automated packaging lines, material handling, and warehouse automation. The retro-reflective detection principle ensures stable and dependable sensing even for dark, reflective, or irregularly shaped objects, providing reliable performance in demanding industrial conditions.

The sensor utilizes 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 and allows operators to position the sensor accurately while quickly verifying alignment. The visible LED ensures consistent detection across the sensor’s full range, minimizing setup time and enhancing operational efficiency.

Electrically, the GRL18-N2431V features dual NPN outputs with support for light-on and dark-on switching modes, allowing versatile integration into a wide range of control systems. The dual-output configuration enables engineers to customize detection logic according to specific application requirements. Built-in protective measures, including reverse polarity, short-circuit, and overload protection, ensure reliable and long-term 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 environments such as factory floors, robotic automation systems, and automated packaging operations. The compact M18 form factor allows installation in tight spaces without compromising durability or performance.

Performance-wise, the GRL18-N2431V delivers a fast response time of under 500 µs, making it suitable for high-speed production lines and automated machinery where rapid and accurate detection is critical. Its wide operating voltage range and low power consumption allow seamless integration into industrial control systems while maintaining consistent and dependable performance over time.

In summary, the GRL18-N2431V combines medium- to long-range detection, precise LED alignment, dual-output flexibility, and rugged industrial durability, making it an excellent choice for engineers and automation professionals seeking reliable, high-performance sensing for material handling, packaging, and robotic automation applications.
