Product Overview

The SICK RAY26 Reflex Array is a photoelectric retro-reflective sensor designed for reliable object detection in industrial environments. Utilizing coaxial optics with autocollimation, it operates without requiring a separate reflector, ensuring simplicity and reduced setup time. The sensor delivers position-independent detection across its light array, making it ideal for detecting objects of varying sizes starting at 3 mm. With a sensing range up to 4.5 meters depending on configuration, the RAY26 offers flexibility in application settings while maintaining consistent performance. Its visible red PinPoint LED light source ensures clear visibility and compatibility with standard detection scenarios. The sensor supports both PNP and NPN switching outputs via IO-Link, enabling seamless integration into diverse automation systems.

Key Features and Technology

The RAY26 Reflex Array leverages a photoelectric retro-reflective principle with coaxial optics to achieve autocollimation, eliminating the need for external reflectors. This technology ensures stable detection regardless of object position within the light array—factory set at 3 mm, 5 mm, or 10 mm minimum sizes—and can be adjusted via IO-Link including conveyor belt suppression. The sensor emits visible red light from a PinPoint LED, providing high visibility and precise beam targeting with a spot size of 55 mm × 9 mm at 1 meter distance. Position-independent detection ensures consistent performance across different object placements. Additionally, the sensor supports manual or IO-Link-based conveyor belt suppression to prevent false triggers during material transport.

Technical Characteristics

The RAY26 Reflex Array has dimensions of 24.6 mm (W) × 82.5 mm (H) × 53.3 mm (D), featuring a rectangular housing design optimized for compact installation. It operates within a supply voltage range of 10 V DC to 30 V DC, with ripple less than 5 V pp and current consumption at either 25 mA or 40 mA depending on configuration. The maximum sensing range varies from 0 m to 2 m, 0 m to 3 m, or 0 m to 4.5 m based on model settings. Switching outputs are available in PNP or NPN modes via push-pull technology with output functions defined at factory setting: Pin 2 (white) for normally closed NPN or normally open PNP, and Pin 4 (black) for normally open NPN or normally closed PNP. IO-Link mode enables remote configuration of switching mode and suppression settings.

Configuration and Integration

The RAY26 Reflex Array supports flexible configuration through IO-Link, allowing adjustment of minimum object size, conveyor belt suppression, and switching mode (light/dark). Switching mode can be selected via IO-Link interface, with factory default settings available for both PNP and NPN outputs. The sensor provides dual output options: QL1/C (Pin 4) or a dedicated switching output (Pin 2), though Pin 4 and Pin 2 must not be connected to another output simultaneously. Signal voltage levels in PNP mode are approximately VS– 2.5 V (high) / 0 V (low). The sensor includes reverse-polarity protection on both input and output terminals, enhancing safety during installation. IO-Link enables remote parameterization, including suppression settings and object size adjustments, ensuring adaptability to dynamic production environments.

Operating Environment

The RAY26 Reflex Array is designed for operation in industrial environments with ambient temperatures ranging from –10 °C to +70 °C. It features a detection height of 55 mm and is rated for use in standard industrial settings where exposure to dust, moisture, or vibration may occur. The sensor's robust housing ensures reliable performance under typical operating conditions. With an average service life of 100,000 hours at a temperature of +25 °C, the RAY26 offers long-term durability and minimal maintenance requirements. It is suitable for use in environments with moderate to high levels of particulate matter, provided that physical protection is maintained.

Industrial Applications

The SICK RAY26 Reflex Array is ideal for applications requiring reliable object detection without the need for external reflectors. Common uses include presence detection on conveyor lines, product counting, and alignment tasks where position-independent detection is critical. Its adjustable sensing range and suppression features make it suitable for use in packaging, assembly, and material handling processes. The sensor’s visible red light source ensures clear visibility during troubleshooting or maintenance. With support for both PNP and NPN outputs and IO-Link integration, the RAY26 fits seamlessly into existing automation systems, enabling real-time monitoring and adaptive control of production lines.
