Description
3
Coded magnetic sensors are devices suitable for monitoring protections and guards of machines without inertia
which, when linked to a safety module, can create a system with safety category up to SIL 3 according to EN 62061,
up to PL e according to EN ISO 13849-1 and up to category 4 according to EN ISO 13849-1. These products consist
of a sensor that detects the magnetic field and which is connected to the machine structure and of a coded magnetic actuator, which is connected to the movable guard. When the sensor and actuator are approached (closed
guard), the sensor detects the actuator and actuates the electrical contacts. The sensor is designed to be activated
only by the correct coded actuator and not through a common magnet.
Insensitivity to dirt
Magnetic sensors are totally sealed
and retain their safety characteristics
also where dirt and dust are present
(not ferromagnetic material). This characteristic, combined with the design
without recesses, makes them particularly suitable for use in the agricultural
and food industries.
Stainless steel fixing plates
To prevent damage to the fixing slots when fastening on non-perfectly flat surfaces, coded magnetic sensors are equipped with stainless steel
fixing plates. Even in the presence of suitable
fixing surfaces, this solution makes the sensor
more robust against mechanical stresses.
Safety screws for actuators
As required by EN ISO 14119, the actuator must
be fixed immovably to the door frame. Pan head
safety screws with one-way fitting are available
for this purpose. With this screw type, the actuators cannot be removed or tampered by using
common tools.
See accessories on page 310.
Laser engraving
All devices are marked using a dedicated
indelible laser system. These engravings are
therefore suitable for extreme environments
too. Thanks to this system that does not use
labels, the loss of plate data is prevented and
a greater resistance of the marking is achieved
over time.

The magnetic sensors have
been tested and approved for
operation with suitable safety
modules (see list). The use of
complete and tested solutions guarantees the electrical compatibility between the
sensor and safety module, as
well as high reliability.

Wide actuation range
With their built-in features, magnetic
sensors have a wide actuation range,
making them very well suited for applications with large tolerances or where
mechanical properties change over
time.
In this type of sensor, the actuation
distances may vary depending on the
shift direction of the actuator in relation to the sensor.
Actuation from many directions
The coded magnetic sensors were designed to be activated by the
respective actuator from various directions. The customer therefore enjoys maximum flexibility when positioning devices along the
perimeter of the guards.
Protection degrees IP67 and IP69K
These devices are designed to be used in
the toughest environmental conditions and
they pass the IP67 immersion test acc. to
EN 60529. They can therefore be used in
all environments where maximum protec-
tion degree of the housing is required. Due
to their special design, these devices are suitable for use in equipment subjected to cleaning with high pressure hot water jets. These
devices meet the IP69K test requirements according to ISO 20653
(water jets with 100 bar and 80°C).
Series connection of multiple sensors
The coded magnetic sensors can be connected in series with the
only limitation that the overall resistance, of sensors and the related
wiring, has to be not higher than the admitted max. value of the
module, which typically is equal to 50 ohm (see module features).
This is a very high value that, with normal wiring, allows the use of
dozens of sensors without problems. It is also possible to realise
mixed circuit solutions by connecting coded magnetic sensors in
series to safety switches, with the only limitation being the abovementioned maximum electrical resistance.
It should be noted that the series connection of two or more coded
sensors reduces the self-monitoring capacity of the system, see
ISO/TR 24119.
The use of Pizzato Elettrica safety modules is recommended.

Use of coded magnetic sensors for safety applications
A coded magnetic sensor alone cannot be used for safety functions because its operating principles are not considered safe by the standards
(such as the positive opening on mechanical switches). For this reason, a magnetic sensor coded for use in safety applications must always be
connected to a safety module that monitors its proper operation through a circuit with at least two channels.
Limits of use
• Installation must be carried out by qualified staff only.
• Before commissioning and at regular intervals, the correct switching of the contacts and proper operation of the system, consisting of the
sensor and the safety module, must be checked.
• Do not use a hammer for adjustment.
• Do not use the sensor as a mechanical stop.
• Observe the assured operating and release distances.
• Adhere to the EN ISO 14119 requirements regarding low level of coding for interlocks.
• Do not mount the sensor and actuator in strong magnetic fields.
• Keep away from iron filings.
• Avoid any impact with the sensor. Excessive shock and vibrations may affect the correct operation of the sensor.
• The actuator must not strike the sensor.
• In case of damages or wear, the entire device – including the actuator – must be replaced.
• Keep load under the value indicated in the electrical data.
• If the sensors are used without corresponding safety module, the protective fuse recommended in the electrical data must be connected in
series to each sensor contact.
• Turn off the power supply before accessing the switch contacts, also during wiring.
Installation on ferromagnetic material
• If possible do not mount the sensor and
the actuator on ferromagnetic materials.
• To avoid a reduction in the switching
distances, use the special VS SP1BA1
spacer.
