Product Overview

The SICK UM30 ultrasonic sensor is a versatile, high-performance device designed for reliable object detection in demanding industrial environments. Utilizing acoustic time-of-flight measurement, the sensor emits an acoustic pulse that reflects off detected objects and returns to the sensor. The system measures the total acoustic time of flight (t2) and calculates distance using the formula: Distance = speed of sound × t2 / 2. With sensing ranges up to 8,000 mm and countless configuration options, the UM30 delivers virtually unlimited use regardless of object color, gloss, or transparency. Its robust design ensures consistent performance under challenging conditions, making it ideal for applications requiring high accuracy and reliability across diverse materials and environments.

Key Features and Technology

The UM30 employs acoustic time-of-flight technology to detect objects by measuring the round-trip time of an emitted sound pulse. The sensor is immune to contamination, operates independently of object color or surface finish, and provides high measurement accuracy through internal temperature compensation. This ensures consistent performance even in extreme thermal conditions up to 70 °C. The system features individually adjustable sonic beams, allowing precise control over detection range by adjusting sensitivity. This enables direct manipulation of the sensor’s beam behavior—allowing objects to be displayed or blanked with infinite adjustment, offering unmatched flexibility for complex or dynamic applications.

Technical Characteristics

The UM30 ultrasonic sensor offers a sensing range up to 8,000 mm and supports various configurations to match specific application needs. It uses acoustic time-of-flight measurement where the distance is calculated as Distance = speed of sound × total acoustic time of flight (t2) / 2. The sensor provides color-independent detection, ensuring reliable performance across transparent, glossy, or matte surfaces. Internal temperature compensation maintains accuracy over a wide operating temperature range up to 70 °C. Immunity to contamination ensures stable operation in dusty, wet, or dirty environments. Detection range can be adjusted by modifying sensitivity, enabling both slow increases and maximum detection limits based on application requirements.

Configuration and Integration

The UM30 integrates seamlessly via IO-Link, offering fieldbus-level communication for enhanced system productivity. This enables automatic sensor configuration according to the manufacturing process, reducing setup time and increasing operational flexibility. Device replacement is simplified through automatic parameterization, minimizing downtime and improving machine availability. Interference-proof signal transmission ensures reliable data transfer even in noisy industrial environments. Minimal cabling requirements and support for unshielded cables reduce project costs while maintaining performance. The sensor’s ability to adjust sensitivity allows direct control over the sonic beam behavior—enabling real-time display or blanking of detected objects with infinite adjustment options.

Operating Environment

The UM30 is designed to operate reliably in a wide range of industrial environments, with a maximum operating temperature of 70 °C. Its immunity to contamination ensures consistent performance even when exposed to dust, moisture, or other particulates. The sensor’s color-independent detection capability makes it suitable for use with materials that vary widely in appearance—such as transparent, glossy, or dark surfaces. It is engineered to function effectively under challenging conditions where traditional sensors may fail due to surface variability or environmental interference. This robustness ensures dependable operation across diverse industrial settings without requiring extensive calibration or maintenance.

Industrial Applications

The UM30 ultrasonic sensor is ideal for a wide range of industrial applications requiring reliable, non-contact object detection. Its ability to detect objects regardless of color, gloss, or transparency makes it suitable in packaging, material handling, and assembly lines where surface properties vary significantly. The individually adjustable sonic beams allow precise tuning for different product sizes and shapes—supporting both slow increases in detection range and maximum coverage. Applications include level monitoring, presence detection, and object counting in environments with high dust or moisture levels. Its flexibility and reliability ensure it can be deployed across various industries where consistent performance under challenging conditions is essential.
