3 Functions and features

The mobile 3D smart sensor is a photoelectric sensor (hereinafter referred to as “device”). The device measures the distance to the nearest surface point by point.

The device is operated as a system together with an illumination unit. The illumination unit illuminates the scene and the device processes the light reflected by the surface.

The processed data is used to describe the captured scene three-dimensionally. The data is provided via Ethernet and CAN.

The parameters of the 3D data are set via the CAN or Ethernet interface. The parameters of the 2D person detection and the RTSP stream are set via Ethernet.

Dropping the device in its original packaging from a height of ≥ 1 m can cause irreparable damage that is not visible from the outside.

▶ Only use an undamaged device.

3.1 Application area

Permitted application area:

• on mobile machines with supply from on-board systems (with battery) of 12 V DC or 24 V DC nominal voltage
  • in an industrial environment with supply from SELV/PELV according to the technical data
  • in outdoor applications

The device safety is rated for use under the following operating conditions according to EN IEC 61010-2-201:

• altitudes up to 4000 m
• relative air humidity up to max. 90 %, non condensing
- pollution degree 4

The unit is not approved for safety-related tasks in the field of operator protection.

Electromagnetic compatibility (EMC): The unit is designed for use in industrial environments. This product may cause radio interference in domestic areas.

▶ If required, take appropriate EMC screening measures.
