Description
Pulse Frequency
5.76KHz + 5%
The SafeZone Safety Laser Scanner is an optoelectronic device that
uses the diffuse reflection of emitted infrared light to determine the
intrusion of a person or object within a defined area. A rotating
deflection unit periodically emits Class 1 infrared laser light pulses
over a 300° angular range to create a detection zone which is two
dimensional. The reflected light is processed by the SafeZone, which
will send a stop signal by switching the state of its safety relay
outputs, if it is determined that a person or object is within the
predefined detection zone.
Scanning Frequency
8Hz + 5%
Two zones can be created within the maximum scanning range of
the SafeZone through the use of the SafeZone’s Windows based
software. The “Safety Zone” is configurable for a 6m (19.7ft) radius
and the “Warning Zone” up to a 7.5m (24.6ft) radius.
Laser Beam Divergence
15 mrad (0.86°)
Focal Length
30mm (1.18in)
Lens Diameter
30mm (1.18in)
The SafeZone can be used in stationary applications for horizontal
detection in a defined protection zone, in vertical applications for
whole body access detection, and on mobile safeguarding
applications—AGVs (Automated Guided Vehicles).
The maximum value of the machine’s stopping time plus the
SafeZone’s response time must be calculated so that no person can
gain access to a hazard point before the dangerous motion has
ceased.
