DANGER
D
amage to the safety switch due to mechanical stress
Loss of safety function
b
Protect the safety switch from mechanical stress such as impacts or permanent
contact pressure, for example with an additional stop
Mounting location
Se
lect the mounting location so that the safety switch is protected from impacts and
mechanical pressure. If necessary, attached additional stop.
Measures to protect against unintentional actuation
The safety switch can be actuated by any metal objects such as metal chips, doors or
moving machine elements. Constructive measures must be taken so that the safety
switch is only actuated by the intended actuating element.
Distance
If several safety switches are mounted on the machine, they must be mounted at a min‐
imum distance to one another.
Alignment
The safety switch can be mounted with any alignment. If the safety sensor is mounted
with the sensor surface facing upwards, the risk of unintended actuation by loose metal
objects (for example metal chips) or manipulation of the safety switch increases.
Possible mounting methods
There are several mounting methods. The permitted mounting method depends on the
product variant:
•
Flush mounting. The active sensor surface is at the same level as the surrounding
material.
•
Non-flush mounting. The active sensor surface protrudes a bit out of the surround‐
ing material.

4.3.1 Determining the sensing ranges
Sensing ranges S
ao
, S
ar
and S
n
depend on t
he material and form of the actuating ele‐
ment. The specified values assume the following prerequisites:
•
Length and width of the actuating element: Diameter of the active sensor surface
•
Material thickness: 1 mm
•
Material of the actuating element: Structural steel (FE360)
•
Ambient temperature: 25 °C
If the actuating element consists of another material, the specified values for S
ao
, S
ar
and S
n
must be multiplied with the respective correction factor (see table 3, page 13)
(values of sensing ranges see table 12, page 25).
