Safety laser scanners microScan3 Core-0

The new generation of safety laser scanners!

With microScan3 Core, SICK is starting a new generation of safety laser scanners for the protection of hazardous areas, entrances, and hazardous points.

The innovative safeHDDM® scanning technology increases the reliability of the microScan3. It is outstanding in dust and ambient light. It increases the productivity and availability of machines. The housing is rugged. Smart connectivity facilitates safe integration into fieldbus technologies and cuts cabling costs.

Using Safety Designer software, the microScan3 can be intuitively configured and is convenient to commission. The operational status can be called up and read clearly on the multicolored display or via the network. What can first impress, and repeatedly generate enthusiasm? The microScan3 from SICK.

At a glance:

  • Innovative safeHDDM® scanning technology
  • Protective field range 5.5 m, scanning angle 275°
  • Up to 8 freely configurable fields
  • Up to 4 simultaneous protective fields
  • System plug with configuration memory and M12 plug connectors
  • Safe integration via I/Os or via network with EtherNet/IP™ CIP Safety™ or PROFINET PROFIsafe



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.

"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.

Exceptionally reliable

See how rugged the microScan3 is in use.

The microScan3 is highly practical as it is not affected by additional laser scanners or other infrared sources.

The microScan3 is resistant to dirt, dust and ambient light. 


"The microScan3 is significantly more reliable than standard measurement processes thanks to the safeHDDM® scanning technology, thus increasing your productivity."

20 years of experience with safety laser scanners in harsh industrial day-to-day work has been incorporated into the development of the microScan3. It has a high load capability and is characterized by its durability.

Excellent durability and productivity

The compact light metal die-cast housing of the microScan3 impresses in harsh industrial day-to-day work too.

The vibration-resistant mounting systems of the microScan3 enable easy fixing.

Electromagnetic compatibility as standard: electronic components of the microScan3.


"The microScan3 has been developed with demanding and harsh industrial applications in mind down to the last detail. It is the perfect combination of safety and productivity."

The safe network integration of the microScan3 with CIP Safety™ over EtherNet/IP™ is quick and easy. This enables safe communication in addition to centralized configuration and diagnostics. The microScan3 uses standardized M12 plug connectors and the device is easy to replace, saving time and helping to keep costs low.

Low cabling costs and fast device replacement with plug and play

First safety laser scanner with CIP Safety™ over EtherNet/IP™.

The Mini-USB interface enables the microScan3 to be configured and diagnosed quickly using a laptop.

Configuration settings are automatically stored in the microScan3's integrated configuration memory. 


"The microScan3 facilitates machine integration and device replacement through standardized interfaces and integrated configuration memory, thereby saving you time and money."


Using Safety Designer software, the microScan3 can be intuitively configured and is convenient to commission. The multi-colored display clearly indicates the operational status of the laser scanner. Pushbuttons can be used to access details and additional information in cleartext.

Straightforward commissioning and intuitive operation

The LEDs and the multi-colored display of the microScan3 are clearly visible.

Important diagnostic messages can be viewed on the microScan3 using pushbuttons and the display.

The configuration and diagnosis software Safety Designer is easy to use.


"The microScan3 is intuitive to use. After the Safety Designer software has been configured, you can carry out device diagnosis during operation using the display and pushbuttons."
