Safety handles P-KUBE 2
This integrated closing device can be applied on guards or protections of perimetric safety barriers, where it is required control on access to
dangerous areas of a machinery or plant.
Application field
One of the most relevant features of the NG line combined with P-KUBE 2 handle is the optional connection
in series of several switches, up to a maximum number of 32 devices, while maintaining the maximum PLe
safety level prescribed by
the EN 13849-1 standard and the SIL3 safety level according to
the EN 62061 standard. Such connection method is permitted
in safety systems where a safety module, which evaluates the
outputs of the last NG switch, is present at the end of the chain.
The fact that the PLe safety level can be maintained, even with
32 switches connected in series, is indicative of the extremely
safe structure found inside each individual device.
Maximum safety with a single device
Constructed with redundant electronic technology, the NG series switches combined with P-KUBE 2 handle,
make it possible to create circuits having maximum PLe and SIL3 safety levels by fitting just one device on
the protection. This avoids expensive wiring on the field and allows quicker installation. Inside the panel, the two electronic safety outputs must
be connected to a Pizzato Elettrica safety module or to a safety PLC.

Connection of several switches in series
The new P-KUBE 2 safety handle, mounted in combination with the NG series RFID safety switch with block, creates an integrated protection
closing system with relating control of access to dangerous areas; such new combination makes it possible to obtain, with one single device,
an access control function complying with category 4, PLe according to EN 13849-1 or SIL3 according to EN 62061.
Presentation
NG series features an electronic system based on RFID technology to
detect the actuator. This system gives a different coding to each actua-
tor and makes it impossible to tamper with a device by
using another actuator belonging to the same series.
The actuators may have millions of different coding
combinations, and are therefore classified as actua-
tors with a high coding level, according to ISO 14119.
RFID actuators with high coding level Anti-panic release button
The release button, facing the inside of the
machine, allows an operator which may have
been involuntarily trapped to get out, even
in case of power cuts and in any operating
condition. To reset the switch, just return the
button to its initial position.
The anti-panic button can be freely length-
ened by means of appropriate extensions,
so that it can also be mounted on very thick
uprights (see accessories).
5 LEDs for immediate diagnosis
As the LEDs have been designed for
quick immediate diagnosis, the status of
each input and output is highlighted by
one specific LED. This makes it possible
to quickly identify the interruption
points in the safe chain, which device
is released, which door is opened and
any errors inside the device. All that in a
straightforward way without needing to
decode complex blinking sequences.
Centring
The switch is provided with a wide
centring inlet for the actuator pin.
Such solution makes it easier to
align the actuator with the hole
found in the head during the fitting
stage. Moreover, this solution
drastically reduces any probable
collisions between the actuator
and the switch, also allowing it to
be fitted on inaccurate doors.
Dustproof
The switch is provided with a through hole
for inserting the actuator and, thanks to this
peculiarity, any dust which may go inside the
actuator hole can always come out of the opposite
side instead of being left there. Moreover, the lock
pin is provided with an external diaphragm gasket
which makes it suitable for any environment
where dust is present.
The NG series switches by Pizzato Elettrica,
besides having an IP67 protection degree,
have passed the test proving their IP69K
protection degree according to the
prescriptions established by the ISO 20653
standard. Therefore they are suitable for use in
machineries subjected to intense washing with high pressure and high
temperature water jets and for any condition or environment where a
particular attention for cleanness and hygiene is required, such as in
food or pharmaceutical industry.
