4.3.10.3 Distance from walls
The availability may be impaired if the protective field stretches as far as a wall or a
dif
ferent object. A distance of 65mm is therefore recommended as a tolerance.

Recommended distance of the protective field from the wall: 65mm
If the distance between the protective field and the wall is so large that a person
c
an stand between them and the protective field is not high enough to recognize the
upper body of the person, this person might not be detected. In this case, appropriate
measures are required to prevent this occurring, e.g., deflector plates or a fence.
4.3.11 Hazardous point protection
Hazardous point protection
T
he safety camera sensor is mounted in a stationary application, for example on a
machine where the operating personnel must stay close to the hazardous point. A fixed
barrier with a height of at least 1,200mm is located in front of the hazardous point.
The operating personnel can reach over the barrier and through the detection zone into
the hazardous point. But the operating personnel cannot climb over the barrier. If there
is no such barrier available, access protection may be required.
When used for hazardous point protection, the safety camera sensor detects the hand
or arm of a person. The camera sensor is typically aligned vertically.
4.3.11.1 Protective field
Protective field
In ha
zardous point protection, the minimum distance typically determines the position
at which the device is mounted. Access to the hazardous point shall only be possible
through the protective field.
For hazardous point protection, a resolution of Hand or Arm is suitable in most cases.
Due to this resolution, the camera sensor is not suitable for finger detection.
