Application
Danger!
In security applications, the sensor must be operated on a quali-
fied safety switch amplifier from
Pepperl+Fuchs (e.g., KFD2-SH-Ex1).
Observe the "exida Functional Safety Assessment" document, which belongs to this
sensor and is available as part of the product
documentation from www.pepperlfuchs.com.
Attention!
NAMUR-compliant switch amplifiers can,
due to a low current consumption at the recorded measuring plate (0.2 mA ... 1 mA), incorrectly report cable breaks (required in
accordance with EN 60947-5-6:2000: 0.4 mA
... 1 mA).
