Great performance at great distance

For reliable distance measurement, both indoors and outdoors: The Dx1000 long range distance sensor with infrared laser is ideal for use on cranes, for detecting vehicles in traffic applications, and for measuring hot steel slabs in a steel mill. The Dx1000 features exceptional versatility in any application – HDDM+ (High Definition Distance Measurement with multi-echo technology) enables distance measurements with high measurement accuracy, even in the presence of ambient light, rain, snow, and fog. It excels at axial object tracking and quickly detecting the edges of objects moved in from the side. The device does all this at measurement cycle times of down to one millisecond, making it ideal for use in control loops.

At a glance
  • Long range distance sensor with infrared laser featuring HDDM+ technology
  • Measures natural objects (DT1000) or reflectors (DL1000)
  • Dust-proof and waterproof housing (IP 65 and IP 67) made of highly corrosion-resistant aluminum alloy
  • Configurable digital inputs and outputs, analog output and fieldbus interfaces (dependent on variant)
  • Measures hot surfaces (DT1000)


Innovative technology ensures reliable measurement results

When it comes to taking reliable measurements of extremely long distances both indoors and out, the Dx1000 long range distance sensor is particularly impressive thanks to its exceptional performance. Equipped with the modern HDDM+ technology, the Dx1000 ensures stable measurement results in a rugged housing, even in inclement weather. Designed by SICK, this measuring technology is the ideal choice for adverse ambient conditions and offers a flexible range of applications at high speeds.

Reliable distance measurements in inclement weather

The innovative HDDM+ technology of the Dx1000 enables measurement at long distances and is characterized by low noise in the measured value data as well as multi-echo capability

Very high resistance to ambient light and faults in the measurement path which could be caused by environmental factors such as rain, snow or fog

Housing made of corrosion-resistant aluminum alloy, dust- and water-resistant according to IP65 and IP67 - connection via industrial-grade M12 plug connector

High reliability even under adverse ambient conditions

High measurement uncertainty with intuitive operation

In most applications, the distance sensor receives exactly one echo from the reflection on the measuring object and converts this into a distance value. In real application situations, protective windows or environmental influences such as precipitation in the measurement path could cause unwanted echos. Thanks to HDDM+ with multi-echo technology, the useful echo can be identified and selected for distance measurement. This enables distance measurements with high measurement reliability, even in the presence of multiple echoes.

Make the right selection quickly and easily

Graphic selection of the useful echo With the convenient SOPAS ET user interface, the useful echo can be identified graphically from the PC and selected for distance measurement

Innovative distance measurement in compact housing

The Dx1000 with HDDM+ is perfectly suited for the measurement of very long distances - with relatively short measurement cycle times as little as 1 ms and low noise in measurement value data. The sensor variants DT1000 for distance measurement on natural objects and DL1000 for measuring on reflectors cover a wide spectrum of uses and offer high flexibility in application. When measuring on natural objects, the DT1000 reaches distances of over 450 m. The DL1000 has a maximum sensing range of 1,500 m when measuring on “diamond-grade” reflective tape.

Designed for all kinds of requirements

In addition to axial object tracking, whereby the measuring object moves continuously along the laser beam, the Dx1000 is also suited for applications in which the measuring object enters the laser beam from the side, e.g., when measuring edges

The measurement technology of the DT1000 is designed for distance measurements on hot surfaces, meaning it is perfectly suited for non-contact measurement or positioning hot steel slabs

The scalability of the measuring range represents a key feature of the DT1000: When measuring on natural objects, the sensing range of the sensor can be increased and optimally adjusted to the measuring task by setting a longer measurement cycle time

High level of application flexibility
