Product Overview

The SICK AS30 is a compact array sensor designed for precise web guiding and positioning applications. Operating in reflector mode, it delivers reliable detection of thin materials through its proximity sensing technology. With a small footprint and optimized housing design, the AS30 integrates seamlessly into automated production lines where accurate material alignment is critical. The sensor features a white LED light source with a defined light spot size of 38.9 mm x 11.1 mm, enabling consistent detection across a working range of 20 mm to 30 mm. Its high resolution of 1 µm and minimum detectable object (MDO) of 0.2 mm ensure precise positioning even for very thin or small features. Ideal for applications requiring fine control over material movement, the AS30 offers reliable performance with minimal maintenance.

Key Features and Technology

The AS30 leverages a proximity system in reflector mode to detect objects based on reflected light, ensuring stable operation during dynamic web handling. Its functional principle is optimized for web guiding and positioning tasks, providing accurate feedback for material alignment. The sensor operates with a default setting of web guiding, making it intuitive for integration into existing systems. With a sensing distance of ≤ 25 mm and a measurement range of 30 mm, the AS30 maintains consistent performance within defined limits. Its high resolution (1 µm) and repeatability of 0.03 mm ensure precise and repeatable positioning. The sensor also features an output time of just 1 ms and a cycle time greater than 1.1 ms, enabling fast response times suitable for high-speed production environments.

Technical Characteristics

The AS30 has dimensions of 31 mm (W) x 62 mm (H) x 52.2 mm (D), making it a compact solution for space-constrained installations. It operates within a supply voltage range of 18 V to 30 V, with ripple tolerance of ≤ 5 V. The current consumption remains low at less than 3.1 W, contributing to energy efficiency. The sensor uses a white LED light source and has a light spot size of 38.9 mm x 11.1 mm for consistent detection. Its working range is 20 mm to 30 mm, with a sensing distance limited to ≤ 25 mm. The minimum detectable object (MDO) is 0.2 mm, and the resolution is 1 µm. Repeatability of 0.03 mm ensures consistent performance over time. All electrical connections are protected against reverse polarity via U V connections.

Configuration and Integration

The AS30 supports IO-Link communication with VendorID 26 and DeviceID HEX 0x80020B (DEC 8389131), enabling seamless integration into modern industrial automation systems. This allows for real-time parameter monitoring, diagnostics, and configuration via a connected controller or HMI. The sensor is designed to be easily installed in standard mounting configurations with its middle housing design. IO-Link connectivity ensures reliable data exchange while maintaining low cable requirements. The output time of 1 ms and cycle time exceeding 1.1 ms support high-speed control loops. Proper installation requires adherence to supply voltage tolerances (18 V to 30 V), ensuring stable operation within defined limits.

Operating Environment

The AS30 is designed for use in industrial environments with ambient temperatures and humidity conditions typical of production lines. It operates reliably under standard environmental conditions, provided supply voltage remains within the specified range of 18 V to 30 V. The sensor must not be exposed to voltages that fall below or exceed these tolerances, as this may compromise performance or safety. Reverse polarity protection is built into the U V connections, ensuring safe operation even in case of accidental wiring errors. While specific environmental ratings are not provided, the sensor is engineered for robustness in typical industrial settings where consistent and reliable detection is required.

Industrial Applications

The SICK AS30 is specifically suited for web guiding and positioning tasks in industries such as packaging, printing, and material handling. Its ability to detect objects with a minimum detectable size of 0.2 mm makes it ideal for aligning thin films, tapes, or sheets during automated processing. The sensor’s compact dimensions and precise resolution support integration into high-speed production lines where accurate positioning is essential. Applications include roll-to-roll operations, label placement, and material feeding systems. Its IO-Link capability enables direct communication with automation systems, allowing real-time feedback for closed-loop control. With a sensing distance of ≤ 25 mm and a working range up to 30 mm, the AS30 delivers consistent performance in dynamic environments where precision is paramount.
