2 Safety information
2.1 General safety notes
This chapter contains general safety information about the safety switch.
Further safety information is provided in the respective chapters to cover the specific
situations in which the product may be used.
DANGER
Hazard 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.
bPlease read this document carefully and make sure that you understand the con‐
tent fully before working with the device.
bFollow all safety notes in this document.
NOTICE
The adhesive strip above the LED displays must not be removed in order to achieve the
specified enclosure rating.
2.2 Intended use
The safety switch is an inductive safety switch which is activated by actuating elements
(metal objects) without making contact. The safety switch is suitable for the following
applications:
•Safe position and area determination of metal objects
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.
2.3 Improper use
The safety switch is not 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‐
viced 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.

Mechanical mounting, electrical installation, and commissioning
For 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 Product description
3.1 Structure and function
Description of operation
The safety switch is an inductive safety switch which is activated by actuating elements
(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.

5Actuating element
Assured switch on distance (Sao)
Distance from the active sensor surface within which the presence of the actuating ele‐
ment can be safely detected.
The assured switch-on distance is the important value for safe applications.
Sensing range (Sn)
Is detected 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)
Distance from the active sensor surface outside of which the presence of the actuating
element is reliably detected.

3.2 Product characteristics
3.2.1 Protective functions
DANGER
Loss of cross-circuit monitoring when output load at the OSSDs is too high
Loss of safety function
bThe safety switch must always be operated within the limits of the prescribed and
specified technical data.
The safety switch is available for the following internal protective functions:
•Short-circuit protection at all outputs
•Cross-circuit monitoring at the OSSDs
•Overload protection at the OSSDs
•Supply voltage reverse polarity protection
3.2.2 Status indicators
LEDs on the device
The safety switch signals the operational status via an LED.
