Accessories
Series connection with Y-shaped M12 connectors
To facilitate and simplify the series wiring of the safety devices, a variety of accessories designed specifically for this purpose are available. With
the help of the proven M12 round connector and the connection of standard elements, safety equipment of Category 4, SIL3 and PL e with up to
32 elements connected in series is possible. All of which is possible without the risk of connection errors and with a high IP67 protection degree.
The safety circuits consist of a 24Vdc power supply unit, a number of extensions to the installed devices, Y connectors for branching out from the
chain to each individual device and a terminating plug.
In addition to the power supply unit, a suitable safety module is used to assess the state of the safety outputs within the safety chain.
Devices suitable for series connection
The series may consist both of devices that are identical to one another
(homogeneous series) or that belong to different series (mixed series).
Only the following Pizzato Elettrica devices may be connected in series
using the Y connectors:
ST series safety sensors with RFID technology: ST D•31•M•,
STD•71•M•
NG series safety switches with solenoid and RFID technology: Any item
with an M12 connector for series connection with a “Y” connector or
with option: K950, K951, K952.
NS: Any item with an M12 connector for series connection with a “Y”
connector or with the option “integrated cable or connector”, letter “Q”.

5 Grey I4 Solenoid activation input
Note: By activating/deactivating input I4, all switches of the NG and NS series in the chain
simultaneously block/open all guards. Activation and deactivation of input I4 has no effect on
the ST sensors and HX hinges in the chain.

Attention! For proper operation of the devices connected in series via cables, Y connectors or junction boxes, it is necessary to pay particular
attention to the voltage drop that occurs in the circuit. Pay particular attention to the flowing currents and cross-section/length of the used cables
to ensure that the supply voltage of the components at the end of the series connection remains within the specified limit values during effective
operation.
