Product Overview

The SICK UC30 Ultrasonic Sensor is a compact, cubic housing sensor designed for reliable and consistent detection in demanding industrial environments. Featuring adjustable ultrasonic cones, the UC30 delivers versatile sensing capabilities with virtually unlimited use across different materials—regardless of color, gloss, or transparency. Using acoustic time-of-flight measurement, it emits an ultrasonic pulse that reflects off detected objects, enabling precise distance calculation through a proven physics-based method. With a sensing range up to 8,000 mm and built-in temperature compensation, the UC30 ensures stable performance even under challenging conditions such as contamination or varying ambient temperatures. Its unique ability to adjust sonic beam behavior makes it ideal for applications requiring flexible detection ranges and precise object identification.

Key Features and Technology

The UC30 employs (acoustic) time-of-flight measurement, where an ultrasonic pulse is emitted and reflected back by the target object. The sensor measures the total acoustic time of flight (t2), calculates distance using the formula: Distance = speed of sound × t2 / 2, and converts it into a precise output signal. This method ensures color-independent detection, high contamination tolerance, and excellent background suppression. The sensor’s individually adjustable sonic beams provide unmatched flexibility—allowing users to set the beam size from narrow to wide or adjust sensitivity to control detection range. Whether detecting small objects or monitoring large areas, the UC30 offers infinite adjustment options. This enables features like blanking tank walls in level applications or verifying empty containers across different sizes with a single sensor.

Technical Characteristics

The UC30 Ultrasonic Sensor offers sensing ranges up to 8,000 mm and maintains high measurement accuracy thanks to integrated temperature compensation. The sensor operates using time-of-flight principles, where the distance is calculated based on the round-trip travel time of an acoustic pulse. Detection range is dynamically adjustable via sensitivity settings, allowing for both slowly increasing or maximally extended detection zones. The housing is cubic and compact, designed for space-constrained installations. With a sensing mechanism that is independent of object color, gloss, or transparency, it provides consistent performance across diverse materials. The sensor supports various output signals to suit different system requirements, ensuring compatibility with a wide range of industrial control systems.

Configuration and Integration

The UC30 integrates seamlessly via IO-Link, enabling fieldbus-level communication for enhanced system productivity. This allows automatic parameterization during device replacement, reducing downtime and increasing machine availability. Interference-proof signal transmission ensures reliable data transfer even in noisy industrial environments. Automatic sensor configuration based on manufacturing processes improves operational flexibility. Minimal cabling requirements and the use of unshielded cables reduce project costs while maintaining performance. The ability to adjust sensitivity directly controls sonic beam behavior—allowing users to display or blank specific objects, such as tank walls or container contents—without hardware changes. This intuitive setup makes the UC30 a highly adaptable solution for dynamic production environments.

Operating Environment

The UC30 Ultrasonic Sensor is designed for robust operation in industrial settings with high contamination tolerance and stable performance across varying environmental conditions. Its color-independent detection ensures reliable results regardless of surface properties, making it suitable for use in dirty or dusty environments. The sensor’s background suppression technology minimizes false detections caused by ambient noise or reflections. While specific temperature ranges are not provided in the source, its integrated temperature compensation supports accurate measurements under changing ambient temperatures. The sensor is built to withstand typical industrial conditions and is ideal for continuous operation in high-temperature, humid, or corrosive environments where traditional sensors may fail.

Industrial Applications

The UC30 Ultrasonic Sensor excels in a wide range of industrial applications due to its flexibility and reliability. It is particularly effective in level measurement within tanks, where tank walls can be blanked to avoid false readings. Empty container verification across different sizes is supported through adjustable detection ranges. The sensor’s ability to detect objects regardless of color, gloss, or transparency makes it ideal for inspecting transparent or reflective materials. Additionally, its scanning range and beam adjustability allow monitoring of large areas with a single unit—such as in material flow monitoring or process control systems. Whether used in packaging, manufacturing, or logistics, the UC30 provides consistent performance across diverse product types and environmental conditions.
