Product Overview

The SICK FlexChain Automation Light Grid is a compact, reliable infrared light grid sensor designed for precise object detection in industrial automation environments. Based on a sender/receiver light grid system, it detects objects with a minimum detectable object (MDO) of 15 mm across a maximum range of 9.1 m. With ten beams spaced 10 mm apart and a detection height of 100 mm, the sensor provides accurate and consistent detection in dynamic settings. Its small footprint—measuring 11.8 mm x 99.2 mm x 24.1 mm—and lightweight design (93 g) make it ideal for integration into tight spaces or automated systems requiring minimal physical intrusion. The sensor operates via a FlexChain host system, enabling seamless communication and real-time monitoring in industrial control setups.

Key Features and Technology

The FlexChain Automation Light Grid uses an infrared light beam system with ten beams separated by 10 mm to detect objects with a minimum detectable object size of 15 mm. The sensor operates using a sender/receiver principle, ensuring high reliability in detecting presence or absence of objects within its operating range of 6.5 m. It is immune to indirect ambient light up to 50,000 lx, making it suitable for environments with moderate lighting conditions. The system includes UV connections, reverse polarity protection, and interference pulse suppression to ensure robust performance under electrical stress. Outputs are protected against overcurrent and short-circuit conditions, enhancing safety and longevity in demanding industrial applications.

Technical Characteristics

The sensor features a detection height of 100 mm and operates within an ambient temperature range of –25 °C to +55 °C. The maximum detection range is 9.1 m, with a minimum range of ≥0 m, ensuring flexibility in installation. It supports supply voltage via the FlexChain host system and has output load capabilities of 100 nF (capacitive) and 1 H (inductive). Light source type is infrared, providing reliable detection without visible light interference. The enclosure rating is IP65 or IP67 when used in outdoor conditions with an external protection housing. Protection class is III, ensuring compliance with safety standards for high-voltage environments.

Configuration and Integration

The FlexChain Automation Light Grid connects via a 0.5 m cable with M8 male connector or a cable with M8 female connector, both featuring a 4-pin configuration. It is designed to integrate directly into FlexChain systems, enabling simple setup and real-time data transmission. The sensor includes circuit protection such as reverse polarity protection, UV connections, interference pulse suppression, and overcurrent/short-circuit protection on outputs—ensuring safe operation even under adverse electrical conditions. This plug-and-play design reduces installation time and minimizes the risk of system failure during integration.

Operating Environment

The sensor is designed for use in industrial environments with ambient temperatures ranging from –25 °C to +55 °C. It operates reliably within a detection range of 6.5 m, and its performance remains stable under varying environmental conditions. Ambient light immunity up to 50,000 lx ensures consistent operation even in moderately lit areas. When used outdoors, the sensor must be installed with an external protection housing due to its IP65 or IP67 rating being applicable only under such conditions. This makes it suitable for both indoor and outdoor applications where environmental exposure is a concern.

Industrial Applications

The FlexChain Automation Light Grid is ideal for use in automated assembly lines, packaging systems, and material handling processes where object presence detection is required. Its high reliability, compact size, and immunity to ambient light make it suitable for detecting small objects or parts with a minimum detectable size of 15 mm. Applications include position sensing, safety monitoring, and product counting in environments with moderate lighting and temperature fluctuations. The sensor’s robust protection features ensure long-term performance in harsh industrial settings where electrical noise and environmental exposure are common.
