2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The safety sensor is designed for application in safety circuits and is
used for monitoring the position of movable safety guards to EN 1088
and IEC 60947-5-3. To actuate the safety sensors, only the BP 6, BP 8,
BP 10 or BP 15 SS actuators can be used.
The safety switches are used for applications, in which the hazardous
situation is terminated without delay when the safety guard is opened.
Only the entire system consisting of the safety sensor (BNS), the actu-
ator (BP) and the safety-monitoring module (AES/SRB/AZR) meets the
requirements of the standard EN 60947-5-3.
The user must evaluate and design the safety chain in accordance
with the relevant standards and the required safety level.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.

(Specifications can vary depending on the application-specific parame-
ters hop, dop and tcycle as well as the load.)
An individual switch can be used in a category 3 or 4 architecture up to
PL e.
If multiple safety components are wired in series, the Performance
Level to EN ISO 13849-1 will be reduced due to the restricted error
detection under certain circumstances.
3. Mounting
3.1 General mounting instructions
• Fitting is only authorised in a de-energised condition
• Do not use the sensor and the actuator as a mechanical backstop
• Any mounting position; Prerequisite: install of the magnet at the front
end of the sensor
• The safety sensor and the actuator must be fitted in a concealed
mounting position in order to avoid a neutralisation of the sensor's
function by simple means.
• Screw both nuts in the provided mounting holes to fix the safety sen-
sor (max. tightening torque 500 Ncm)
• Inseparably fix the safety sensor and the actuator to the safety guard
To avoid any interference inherent to this kind of system and any reduc-
tion of the switching distances, please observe the following guidelines:
• If possible, do not install the safety sensor and the actuator on a
ferromagnetic material.
• Do not install the safety sensor and the actuator in strong magnetic
fields
• Do not subject the safety sensor and actuator to extreme vibrations
and shocks
• Keep away from metal chips
• The mounting distance between two sensors should always be at
least 50 mm
