Product Overview

The SICK Dx80 laser distance sensor is a high-precision, long-range device designed for accurate non-contact measurement in industrial environments. It offers a versatile measuring range from 50 mm to 80,000 mm, with performance optimized under standard ambient conditions. The sensor uses visible red laser light to detect distances and provides reliable results across various surface reflectivity levels. With a resolution of 0.1 mm and measurement accuracy of ±2 mm, it delivers consistent performance for critical positioning tasks. Ideal for applications requiring precise distance detection over extended ranges, the Dx80 combines robustness with ease of integration through standard analog outputs and IO-Link connectivity. Its ability to operate across different reflectivity conditions ensures adaptability in diverse industrial settings.

Key Features and Technology

The Dx80 employs a visible red laser light source with a typical spot size of 5.5 mm × 7.5 mm at 1 meter, ensuring precise targeting on surfaces. The sensor operates across multiple reflectivity conditions: up to 40,000 mm at 90% remission factor and down to 14,000 mm at a 6% remission factor, enabling reliable performance in varying environments. Response time ranges from 33 ms to 68 ms depending on the object and filter settings, ensuring fast feedback for dynamic processes. The sensor supports continuous data output with configurable output times (33 ms to 3000 ms), ideal for real-time monitoring. IO-Link V1.1 integration enables process data exchange, parameterization, diagnosis, and data storage at a transmission rate of 230,4 kbit/s via COM3, enhancing system-level visibility and control.

Technical Characteristics

The SICK Dx80 delivers a measuring range from 50 mm to 80,000 mm under optimal ambient conditions at measurement cycle times of ≤3,000 ms. At 90% remission factor, the range extends from 50 mm to 40,000 mm; at 6% remission factor, it is limited to 50 mm to 14,000 mm, with a potential reduction of up to 40% in maximum range due to ambient temperature. Resolution is 0.1 mm, and measurement accuracy is ±2 mm, with typical temperature drift at 0.1 mm/K. The sensor features a response time between 33 ms and 68 ms, dependent on object properties and filter settings. Output options include current (4 mA to 20 mA, ≤450 Ω) or voltage (0 V to 10 V, ≤10,000 Ω), with a 16-bit resolution. The supply voltage range is 12 V to 30 V, and ripple is limited to ≤5 V pp.

Configuration and Integration

The Dx80 supports flexible integration via standard analog outputs and IO-Link V1.1 functionality. It offers both PNP and NPN push-pull current output types with a maximum output current of ≤100 mA, suitable for compatibility with most industrial control systems. The sensor provides configurable output times (33 ms, 50 ms, 100 ms, 200 ms up to 3000 ms), allowing users to match data sampling rates to application needs. IO-Link enables real-time parameterization, process data access, diagnostics, and data storage through a data transmission rate of 230,4 kbit/s over COM3. This allows seamless integration into supervisory control systems and enables remote monitoring and fault detection without additional hardware.

Operating Environment

The Dx80 is designed for operation under standard industrial ambient conditions. The maximum measuring range at 90% remission factor (50 mm to 40,000 mm) is valid under good ambient conditions and with measurement cycle times of ≤3,000 ms. At the maximum permissible ambient temperature, the sensor’s maximum range may be reduced by up to 40%, particularly at lower reflectivity levels such as 6%. The device operates within a supply voltage range of 12 V to 30 V and is designed for use in environments with ripple ≤5 V pp. While not explicitly rated for extreme temperatures or humidity, it performs reliably in typical industrial settings where ambient conditions remain stable and within specified limits.

Industrial Applications

The SICK Dx80 laser distance sensor is suitable for a range of industrial applications requiring precise, long-range distance measurement. It is ideal for use in assembly lines, packaging systems, and material handling processes where accurate object detection over large distances is essential. The sensor’s ability to function across different reflectivity levels makes it effective in environments with varied surface types. Applications include thickness measurement, level monitoring, position feedback, and object presence detection. Its IO-Link capability supports integration into smart manufacturing systems for real-time diagnostics and process optimization, while its robust design ensures reliable performance in continuous production environments.
