,
z
-resolution at factory setting median "3"
3)
Reflectivity 90%, identical object, identical environment conditions, measurement object
20x20mm²
4)
Minimum value, depends on distance and object, requires testing under application
conditions
5)
For UL applications: for use in class 2 circuits according to NEC only
6)
The push-pull switching outputs must not be connected in parallel
7)
Number of detection fields: up to 16 with logic operation option
8)
Number of inspection tasks: up to 16 (8 of these can be activated via inputs)
9)
1=transient protection, 2=polarity reversal protection, 3=short circuit protection for all
outputs, requires external protective circuit for inductive loads
