azard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
Please read this document carefully and make sure that you understand the con‐
b
tent fully before working with the device.
Follow all safety notes in this document.

applications:
•
The safety switch is used for protecting people.
The safety switch must only be used within the limits of the prescribed and specified
technical data and operating conditions at all times.
Incorrect use, improper modification or manipulation of the safety switch will invalidate
any warranty from SICK; in addition, any responsibility and liability of SICK for damage
and secondary damage caused by this is excluded.

Safe position and area determination of metal objects
t suitable for the following applications, among others:
Environments with increased levels of ionizing radiation
Applications in which the safety switch is exposed to chemicals, for example clean‐
ing in food processing.
Outdoors (only suitable for weather-protected areas of application, Class C accord‐
ing to IEC 60654-1)
2.4 Requirements for the qualification of personnel
The safety switch must be configured, mounted, connected, commissioned, and ser‐
iced by qualified safety personnel only.

Project planning
For project planning, a person is considered competent when he/she has expertise and
experience in the selection and use of protective devices on machines and is familiar
with the relevant technical rules and national work safety regulations.

or the task, a person is considered qualified when he/she has the expertise and expe‐
rience in the relevant field and is sufficiently familiar with the application of the protec‐
tive device on the machine to be able to assess whether it is in an operationally safe
state.
Operation and maintenance
For operation and maintenance, a person is considered competent when he/she has
the expertise and experience in the relevant field and is sufficiently familiar with the
application of the protective device on the machine and has been instructed by the
machine operator in its operation.

3.1 Structure and function
Description of operation
he safety switch is an inductive safety switch which is activated by actuating elements
T
(metal objects) without making contact.
If an actuating element is situated between the active sensor surface and assured
switch-off distance Sao, safety outputs (OSSDs) are safe in the ON state. If an actuating
element is situated outside assured safe switch-off distance Sar, safety outputs
(OSSDs) are in the OFF state.
The machine or its control must safely analyze the signals (for example using a safe
control or safety relays) and stop the dangerous state.

ar
Assured switch on distance (Sao)
tance from the active sensor surface within which the presence of the actuating ele‐
Dis
ment can be safely detected.
The assured switch-on distance is the important value for safe applications.
Sensing range (Sn)
Is de
tected under laboratory conditions.
Typical sensing range of the safety switch. The sensing range can change with the
shape and material of the actuating element. Manufacturing tolerances as well as
external influences such as temperature or supply voltage are not considered.
Assured switch off distance (Sar)
Dis
tance from the active sensor surface outside of which the presence of the actuating
element is reliably detected.

4 Project planning
4.1 Manufacturer of the machine
DANGER
F
ailure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
Carry out a risk assessment before using the safety switch.
b
Do not tamper with, open, or modify the components of the safety switch.
b
Do not repair defective devices – they must be replaced instead.
b
Make sure that switch-on commands which bring about a dangerous state of the
b
machine are not enabled until the protective device is closed.
Ensure that a stop command is triggered if the actuating element is no longer
b
detected (e.g. when the protective device is opened during a hazardous machine
status).
The safety switches must not be circumvented (contacts bypassed), rotated away,
b
removed, or rendered ineffective in any other way. Put measures in place to
reduce possibilities for circumvention.
PROJECT PLANNING 4
4.2 Operating entity of the machine
DANGER
F
ailure to observe operator obligations
Hazard due to lack of effectiveness of the protective device
Changes to the machine and changes to the mechanical mounting of the safety
b
switch necessitate a new risk assessment. The results of this risk assessment
may require the entity operating the machine to meet the obligations of a manu‐
facturer.
Apart from the procedures described in this document, the components of the
b
safety switch must not be opened or modified.
Do not carry out any repair work on components. Improper repair of the safety
b
switch can lead to a loss of the protective function.
4.3 Design
Important information
DANGER
B
ypassing the protective device
Hazard due to lack of effectiveness of the protective device
Avoid incentives to manipulate the safety switch by taking at least one of the fol‐
b
lowing measures:
Attach safety switch outside of the sensing range.
°
Cover safety switch with obstacles or shield.
°
Attach safety switch at the covered position.
°
If possible, do not mount the safety switch with the active sensor surface fac‐
°
ing upwards.
