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 ISO 14119
and IEC 60947-5-3. To actuate the safety sensors, only the BPS 300,
BPS 303 or BPS 303 SS actuators can be used, conventional magnets
are not suitable.
The safety switchgears are classified according to
ISO 14119 as type 4 switching devices.
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 300 with
integrated safety-monitoring module) and the actuator (BPS 300/
BPS 303 or BPS 303 SS) meets the requirements of the standard
IEC 60947-5-3.

3. Mounting
3.1 General mounting instructions
During fitting, the requirements of ISO 14119 must
be observed.
• Fitting is only authorised in a de-energised condition
• Do not use the sensor and the actuator as a mechanical backstop
• Any mounting position, provided that the active surfaces are opposite
• Screw both nuts in the provided mounting holes to fix the safety
sensor (max. tightening torque 300 Ncm)
• Do not install the safety sensor and the actuator in strong magnetic
fields
• If possible, do not install the safety sensor and the actuator on
ferromagnetic material.
• 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.
Safety sensor and actuator must be permanently fitted to the
safety guards and protected against displacement by suitable
measures (tamperproof screws, gluing, drilling of the screw
heads).

3.3 Axial misalignment
A horizontal and vertical misalignment of the safety sensor and the
actuator is tolerated. The possible misalignment depends on the
distance of the active surfaces of the sensor and the actuator. The
sensor remains active within the tolerance range.
The specified switching distances refer to opposedly mounted safety
sensors and actuators.
Assured switching distance: sao = 5 mm,
8 mm (ordering suffix -2211, -2334)
Assured switch-off distance: sar = 15 mm,
18 mm (ordering suffix -2211,

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Fitting of the sensor and the actuator
2. Fitting and integrity of the power cable
3. The system is free of dirt and soiling
(in particular metal chips)
5.2 Maintenance
In the case of correct installation and adequate use, the safety sensor
features maintenance-free functionality.
A regular visual inspection and functional test, including the following
steps, is recommended:
• Check the fitting of the sensor and the actuator
• Remove possible metal chips
• Check the cable for damage.
Adequate measures must be taken to ensure protection
against tampering either to prevent tampering of the safety
guard, for instance by means of replacement actuators.
Damaged or defective components must be replaced.
Recommended Adjustment
Align the safety sensor and actuator at a distance
of 0.5 x s
.

4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
The safety sensors must be wired in accordance with the wire colours
or the pin configuration.
4.2 Contact variants
The contact position shows the actuated sensor function when the
safety guard is closed. The LED is illuminated when the guard is
closed. Inductive loads (e.g. contactors, relays, etc.) are to be provided
with suitable interference suppression circuitry.
