SAFETY LASER SCANNER

CONTROLLED AREAS

SAFETY ZONE

This is the effective protection zone, in which the laser scanner assures the detection of any obstacle having a minimum reflectivity to
infrared light of 1.8%. This means any human body in any possible clothing.
The occupation of this zone causes the switching of the two safety outputs that control the emergency stopping of the machine.
The shape of the zone can be programmed according to the application requirements.

WARNING ZONE

This is the zone in which the laser scanner is able to detect the presence of an obstacle approaching the safety zone.
The occupation of this zone causes the switching of the auxiliary output that can be used to activate light or sound signals or in order to slow
down the hazardous movement. This zone is generally larger than the safety zone.
In this case also the shape of the zone can be programmed according to the application requirements.

ADVANTAGES OF THE LASER SCANNER

• No receiving and reflecting elements
• Simple programming of differently-shaped controlled areas
• Monitoring and protection of large areas
• Horizontal mount for the detection of the body in a dangerous area.
• Vertical mount for the detection of hands and arms or for the detection of the body in access control.
• Use on moving vehicles (AGVs)
• Measurement of object size, shape and position
• Fast and reliable installation

APPLICATIONS

	Area control Example of an horizontally mounted protective field permanently monitored by Pharo. In this way a larger area can be monitored through the detection of the lower limbs of the body.
	Access control If the controlled plane is installed in a vertical position, even very large accesses can be protected. Hands, arms or the whole body can be detected, depending on the chosen resolution. Note: the contour detection is mandatory for the vertical mount / access control applications.
	Protection of Automatic Guided Vehicles (AGV) The vast size of the controlled area allows the AGV to travel at higher speeds with respect to bumper protection. The warning area permits speed reduction in the presence of obstacles. The data measured by the sensor can be sent to the vehicle on the serial interface and used as navigation aid.

Dimensional measurement
The sensor is first of all a measurement device. Therefore, the measurement data of the surrounding environment, which are always available during operation, can also be used for object profile, position and dimensions measurement in industrial automation.
