5.4 Limited detection capability zone
The limited detection capability zone is defined as a region between the optical window and start of the
detection zone. The limited detection capability zone of the SE2L is 90mm from the origin of SE2L (Figure
5-9). Presence of object with low reflectance may not be detected in this zone.
Figure 5-9 Limited detection capability zone
 Measured value will be longer than actual distance of the object if the
background is highly reflective. Additional distance should be included when
configuring the protection zone.
 High reflective background (Ex.: Mirror, corner cube reflector, reflective safety
jacket, road reflector) should be avoided. Reflectance caused by these materials
could lead to false detection in the protection zone.
 Verify the configured areas before actual operation.
 Failing to comply with the above could lead to critical injury or death.
 User should perform risk assessment for possibility of object penetration into
the limited detection capability zone.
