Innovative safeHDDM® scanning technology

The innovative safeHDDM® scanning technology sets new standards for safety laser scanners. By combining a compact design and a wide scanning range, it ensures that the microScan3 retains its field of view even in challenging ambient conditions.

safeHDDM® is based on SICK's proven HDDM process (HDDM = high definition distance measurement). The safeHDDM® scanning technology sets a new benchmark in the analysis of time-of-flight measurement. The process patented by SICK delivers unrivaled measurement results for safety laser scanners by filtering and analyzing numerous single pulses. In this way, safeHDDM® enables a very high level of resistance to ambient light and dust. And the most important part: safeHDDM® ensures safety throughout. Even an object with a remission of just 1.8%, for example black clothing, can be recognized safely by the laser scanner.

How it works

microScan3 – reliable distance measurement based on the principle of time-of-flight measurement With time-of-flight measurement, the sensor emits a pulse beam that hits the target object and then is reflected back. The time that the beam takes to make this journey is evaluated and the distance to the object calculated. microScan3 has a scan cycle of just 30 milliseconds. Thousands of single pulses can be filtered per scan cycle. These single pulses are used by the microScan3 to calculate 715 safe measured values.
275°? 275°! – without a single safety blind spot A significant advantage of a modern laser scanner is that it can be mounted in a corner, enabling the monitoring of two sides of a machine. A scanning angle of 270° is theoretically enough to cover this. Yet SICK goes one step further: The microScan3 is the first safety laser scanner to reach 275°. Without this extra 5°, inaccurate mounting of the laser scanner can easily lead to a safety blind spot of almost half a meter. The microScan3 makes this problem a thing of the past.
