LBK System. 3D safety radar
LBK system detects access or the presence of operators in a dangerous area. In any environmental conditions (dust, smoke, swarf, water aerosols), it guarantees a level of safety never before reached by any other system in the world. The radar waves of the sensor cover the entire dangerous area, creating a 3D protected zone.
Maximum configuration flexibility.
The system is composed of a controller that can be connected to up to 6 LBK-S01 sensors.

  • Perfect alignment among the sensors is not necessary.
  • The software supplied with the system allows for multiple configurations: assisted automatic configuration for regularly-shaped areas and manual configuration for monitoring more complex areas.
  • Programmable muting allows the creation of differentiated intervention areas where operators can gain safe access according to production logic.

Access detection
Access detection
Each LBK sensor can create a configurable virtual barrier that delineates an alarm area and a pre-alarm area, providing a secure signal that can slow down or stop the machine.
Restart prevention
Restart prevention
The system can detect operator micro-movements and prevent machine restart, ensuring complete operator safety.
The controller manages the statuses of all the sensors, including the muting function, used to temporarily deactivate some sensors when they are not required to detect motion in the area. When properly configured, the muting function allows operators to temporarily access non dangerous areas.

The Inxpect Safety Application can be used to configure the alarm and pre-alarm areas in 3D, and to create optimum coverage of the dangerous area using different beam angles from the sensors, which is then validated by the software once the system is physically installed.

Response time
The system response time is less than 100ms, which reduces the area required to protect the machine to a minimum.
