Product Overview

The SICK Dx1000 laser distance sensor is a high-precision, long-range measurement device designed for demanding industrial environments. Based on HDDM (Holographic Distance Detection with Modulation) technology, it delivers accurate and reliable distance measurements over distances from 0.2 meters to 1,500 meters when using 'diamond grade' reflective tape. The sensor offers flexible resolution settings ranging from 1 µm to 100,000 µm, enabling precise measurement depending on application needs. With a typical measurement accuracy of ±15 mm at +23 °C after a warm-up time of over 15 minutes, the Dx1000 ensures consistent performance in critical automation tasks. Its fast response time (3 ms to 384 ms) and low cycle times (1 ms, 4 ms, or 16 ms) make it suitable for dynamic environments requiring real-time feedback.

Key Features and Technology

The Dx1000 leverages HDDM technology to provide robust distance sensing with high signal-to-noise ratio. It supports selection of either the first or last echo within a defined distance and signal level range, enabling flexibility in detecting targets based on application requirements. The sensor operates under maximum ambient light conditions of 100 kLux (sunlight), ensuring reliable performance even in bright environments. Measurement accuracy is typically ±15 mm at +23 °C after sufficient warm-up time (>15 min). Repeatability is ≥1 mm under statistical error 1σ, with constant environmental conditions. The light spot size at 1 meter is 5 mm × 20 mm, which helps in identifying target positioning and minimizing measurement errors due to reflectivity variations.

Technical Characteristics

The Dx1000 offers a measuring range of 0.2 m to 1,500 m on 'diamond grade' reflective tape. Resolution is adjustable from 1 µm to 100,000 µm. Typical measurement accuracy is ±15 mm at +23 °C after warm-up time exceeding 15 minutes. Repeatability is ≥1 mm under constant environmental conditions and statistical error 1σ. Response times range from 3 ms to 384 ms depending on filter settings and cycle time. Measurement cycle times are available in 1 ms, 4 ms, or 16 ms options. Output time is ≥1 ms. The typical light spot size at a distance of 1 m is 5 mm × 20 mm. Analog output provides a 4 mA to 20 mA current signal with 16-bit resolution. Digital outputs are available in two to four channels (PNP/NPN), each capable of delivering up to 100 mA maximum current.

Configuration and Integration

The Dx1000 supports multiple communication interfaces for seamless integration into existing systems. It features Ethernet with TCP/IP functionality, enabling parameterization and real-time transmission of measurement data at a data rate of 10/100 MBit/s. Serial communication via RS-422 is available, with optional switchability to SSI mode. SSI output is also supported, allowing flexibility in interface selection based on system requirements. All interfaces support function parameterization and output of measurement data. The sensor provides a single analog current output (4–20 mA) with 16-bit resolution for integration into control systems or HMI displays. Digital outputs (2 to 4 channels) offer PNP/NPN push-pull configurations, each with a maximum output current of ≤100 mA, suitable for direct connection to logic circuits or safety relays.

Operating Environment

The Dx1000 is designed for operation in industrial environments with typical performance guaranteed at ambient temperature +23 °C. Measurement accuracy and repeatability are specified under these conditions after a warm-up period of more than 15 minutes. Performance may vary depending on environmental factors such as temperature, humidity, and ambient light levels. The sensor is rated for operation in bright environments with maximum ambient light up to 100 kLux (sunlight). Measurement accuracy is dependent on reflector size and measuring cycle time, particularly when using reflective surfaces like 'diamond grade' tape. For optimal results, ensure the target surface has sufficient reflectivity and that the sensor is properly aligned within its specified range.

Industrial Applications

The SICK Dx1000 laser distance sensor is ideal for applications requiring long-range, high-precision distance measurement in dynamic industrial settings. It is commonly used in material handling, packaging, and assembly lines where accurate object detection over extended distances is essential. Suitable for use with reflective tapes or targets, it enables reliable positioning and presence detection in environments with high ambient light. Applications include level monitoring, thickness control, robotic guidance, and automated inspection systems. Its flexible output options—digital, analog, and serial—allow integration into diverse automation architectures. The sensor’s fast response times and adjustable resolution support real-time process control, making it a reliable choice for precision measurement in manufacturing and logistics environments.
