The SICK GRSE18-N1121V (part number 1085939) is a high-performance retro-reflective photoelectric sensor designed for precise and reliable object detection in medium-range industrial automation applications. Part of the GRSE18 series, this sensor combines advanced optical technology with a durable M18 cylindrical housing, ensuring consistent and dependable performance across a variety of industrial environments.

A key feature of the GRSE18-N1121V is its medium-range sensing capability, capable of detecting objects from 50 mm up to 6 m when used with a suitable reflector. This makes it ideal for applications such as conveyor monitoring, packaging systems, material handling, and automated production lines. The retro-reflective detection principle ensures stable and dependable sensing even when detecting dark, reflective, or irregularly shaped objects, providing reliable operation in demanding 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 accurately position the sensor while quickly verifying proper alignment. The visible LED ensures consistent detection performance throughout the sensor’s range, reducing setup time and improving operational efficiency.

Electrically, the GRSE18-N1121V features dual NPN outputs with configurable light-on and dark-on switching modes, enabling flexible integration into a wide range of control systems. The dual-output configuration allows engineers to adapt detection logic to specific application requirements. Built-in protective features, including reverse polarity, short-circuit, and overload protection, enhance the sensor’s reliability and longevity 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 GRSE18-N1121V delivers a fast response time, making it suitable for high-speed production lines and automated machinery where rapid and precise detection is essential. 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 GRSE18-N1121V 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 solutions for material handling, packaging, and automated manufacturing applications.
