Safety laser scanners

Thanks to the configurable protective and warning fields, safety laser scanners can be used in a variety of ways for danger zone and access guarding. Their compact design makes them ideal both for stationary and for mobile applications. Our RSL 400 safety laser scanners are characterized by their performance, robustness and easy handling. Thanks to its high operating range of 8.25 m and a scanning angle of 270°, it can monitor even large areas. The series also includes models for integration via PROFIsafe/PROFINET interface and models with data output for the navigation of automated guided vehicles.

Highlights

IPIC_RSL400_Angular_resolution_500x500px

Unique technology for robust operation

With the RSL 400, the entire transmitting/receiving system rotates creating an especially narrow and uniform laser spot over the entire scanning range. This provides the devices with a high angular resolution of 0.1°, making them very adept at filtering objects that are not safety-relevant, such as dust and particles in the air.

Efficiently monitored

With the 270° scanning angle and operating range of up to 8.25 m, the RSL 400 can safeguarding even large areas with just one device. The 2-in-1 solution makes the devices even more efficient: by means of 2 independent protective functions, each with its own safety output, the RSL 400 performs the tasks of two devices.

PPIC_RSL400_Scanner_head_connection_unit_CMYK_500x500px

Removable connection unit

The connection unit of the RSL 400 is removable and can be mounted separately. The scanning head thus remains protected and can simply be attached afterwards.

Fast device exchange: It takes less than 30 seconds to swap out the scanner: turn two screws by 90° and replace the scanner head. Without realignment, readjusting and configuration effort, as the configuration memory is integrated in the connection unit

Three communication options

Suitable access is always guaranteed with three means of communication for configuration and diagnosis. In addition, all RSL 400 models are already network-capable thanks to the standard Ethernet-TCP/IP interface, e.g. for diagnosis via central access points.

Ethernet TCP/IP
USB (from RSL 420)
Bluetooth

Integrated display

The large characters on the integrated display are easily visible even from a distance. Various functions and messages are thereby always in view.

The built-in electronic spirit level allows for quick alignment of the device

Particularly easy

Integration is particularly easy with the RSL 410, using an 8-pin M12 connector.

Connector or cable

Connection units for the RSL 420 to 445 models are available with plugs or cables in selectable lengths.

200 configurable fields

100 switchable field pairs or 50 switchable 4-field sets offer optimum adaptation to various movement conditions, e.g., with AGVs or robots. With its two parallel protective functions, the RSL 400 works like two devices in one, or it can provide an additional, upstream protective field. In the PROFIsafe version, the RSL 400 monitors even four protective fields simultaneously.

100 switchable field pairs:
1 protective field + 1 warning field

10 switchable 4-field sets:
1 protective field + 3 warning fields

2 x 10 field pairs, independently switchable:
1 protective field + 1 warning field each

50 switchable 4-field sets:
2 protective fields + 2 warning fields
PROFIsafe: also 4 protective fields

Application

RSL_sicherung-gefährlicher-bereiche_700x500px

Guarding of hazardous areas

Requirement:
The hazardous working range of the machine is to be guarded against entry by and the presence of persons. The contour of the monitored area is to be adapted to the contour of the machine.

Solution:
The RSL 400 safety laser scanners use configurable protective fields for area monitoring. Thanks to the 8.25 m operating range and 270° scanning range, large areas can be guarded with just one device.

Restart protection and monitoring of hidden areas

Requirement:
To prevent danger, the process is not permitted to restart until it has been ensured that no persons are in the work area or in the hidden area.

Solution:
The RSL 400 safety laser scanners monitor the presence of persons with a configurable protective field. The device is connected via the I/O interface or – for integration in industrial Ethernet networks – via the PROFIsafe/PROFINET interface.

Guarding and navigation of automated guided vehicles (AGVs)

Requirement:
The transportation path of the AGV must be guarded by means of safety sensors. The protective fields are to be flexibly adapted to the movement and loading situation. If the principle of natural navigation is used, the device is at the same time to provide the measurement data for the navigation software.

Solution:
The RSL 400 safety laser scanner merges safety technology and high-quality measurement value output in a single device. It has a scanning range of 270° and 100 switchable field pairs. Two scanners therefore provide optimum guarding of the AGV. The measurement data has a high angular resolution of 0.1° and a low measurement error.

Access guarding using sensors outside of working range

Requirement:
Access to dangerous areas by persons and vehicles is to be monitored using safety sensor technology. The sensors must not hinder free movement within the working range.

Solution:
The RSL 400 safety laser scanner is installed above the access area and the protective field is aligned vertically. This ensures that the working range is not restricted. By using two safety functions working in parallel, one RSL 400 can monitor two stations simultaneously and independently from each other.
