HX BEE1
HX series safety hinge switches
Description
The electric switch is fully integrated into the mechanical hinge so that it is virtually invisible to an inexpert eye. This, asides from being an aesthetic advantage, guarantees greater safety as a switch which is difficult to identify is consequently even more difficult to tamper with. The rear mounting without screws in sight and the very precise line mean the switch can be perfectly integrated even with guards of machinery with a very precise design.
As the HX series safety hinge switches are in stainless steel, these devices can be used in environments where particular attention must be paid to hygiene making them suitable for a variety of applications, ranging from the food and pharmaceutical sectors to the chemical and marine sectors.
Maximum safety with a single device
The HX BEE1 series hinge switches are constructed with redundant electronics. As a result, the maximum PL e

This connection type is permissible in safety systems which have a safety module at the end of the chain that monitors the outputs of the last HX switch.
The fact that the PL e safety level can be maintained even with 32 sensors connected in series demonstrates the extremely secure struc‑ ture of each single device.

Adjustment of the switching point
The switching point of the switches can be set with a flat‑blade screwdriver.
Adjusting the switching point allows for any calibration for large size guards. After calibrating the switch, it is always necessary to close the hole using the safety cap supplied.
Cable with connector at the back
The version with a cable with M12 connec‑ tor at the back offers the best combination of aesthetics and simple connection.
This solution allows the wiring to be hidden. At the same time, it facilitates the connection and disconnection of the wiring from inside the machinery.

Basic activation angle variants
On request, versions with a switch base activation angle of 15° mul‑ tiples (e.g. 45° or 90°) are available.
The different activation angle does not exclude the possibility of fine adjustment of the switching point by means of the adjustment screw in the switch. Any change in the base operating angle does not alter the maximum mechanical switch travel.
Opening angle up to 180°
The mechanical design of the switch also allows use on guards with an opening angle of up to 180°.

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 protection
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).
Materials
With this new series in AISI316L stainless steel, Pizzato Elettrica offers an extensive range of devices suitable for environments where special attention must be paid to cleanliness and hygiene.
The accurate surface finish allows these devices to be used for a variety of applications, ranging from the food and phar‑ maceutical sectors to the chemical and marine sectors.
For heavy duty applications
Specially designed for heavy industrial applications, these hinges are made of high‑thickness microfusion materials with high strength mechanical properties. The maximum loads indicated in the techni‑ cal specifications are those that the hinge can withstand without any lubrication, for one million opening and closing cycles,
while maintaining its features as a safety device in perfect efficiency.
Additional hinges
To complete the installation, various types of additional hinges are available to be used in a variable number depending on the weight of the guard.
These hinges have the same aesthetic and mechanical structure but cost less as they contain no electrical parts.
Laser engraving
Pizzato Elettrica has introduced a new laser engraving system for stainless steel switches of the HX series.
Thanks to this new system, engravings on the products are indelible.
Mechanical or electronic contact blocks
Internally equipped with innovative concepts, the HX series safety switches can be supplied both with electromechanical safety contacts with posi‑ tive opening, or with self monitoring redundant electronic safety outputs. This allows the customer to choose between the most cost‑effective solution (mechanical contacts) or a maximum security solu‑ tion (electronic outputs).
With cable or connector
The electrical connection via integrated cable or M12 connector option makes the device suitable for the most diverse applications. The con‑ nector versions allow faster device replacement and installation, by making incorrect wiring connection impossible. The cable versions, on the other hand, offer the best value for money. Both the cable as well as the connector versions are available with mechanical or electronic contact blocks.
Three different output directions
Designed for flexibility, the HX series safety hinges are equipped with three different output directions for the electrical conduc‑ tors. Directions from below or from above allow the same exit direction of the conduc‑ tor to be maintained, both for right and for left‑hand doors. The direction from behind has the ultimate aesthetic, cleanliness and hygiene result. All three electrical output directions are available with output cables in various lengths or with M12 connector.
Four LEDs for immediate diagnosis
The versions with electronic contact block are equipped with four signalling LEDs. Each LED represents a specific hinge function, this greatly facilitates switching point adjustment via the immediate visual indication for the installer during the adjustment phase. There are also three separate LEDs available: one for input status, one for output status, and one for
general device status. For serial applica‑ tions, this independence enables identification of any interruptions in the safety chain and of any internal errors. All of this at a glance, with‑ out needing to decode complex flashing sequences.
Gold-plated contacts
The contact blocks of these devices can be sup‑ plied gold‑plated upon request. Ideal for applica‑ tions with low voltages or currents; it ensures increased contact reliability. The high‑thickness coating > 1 micron ensures the mechanical endur‑ ance of the coating over time.

Pizzato Elettrica CS
series safety module
Possibility of series connection of multiple hinges for simplifying the wiring of the safety system, whereby only the outputs of the last hinge are evaluated by a Pizzato Elettrica safety module (see table with compatible safety modules). Each HX switch is provided with a signalling output, which is activated when the respective guard is closed. Depending on the specific requirements of the application, this information can be evaluated by a PLC.
Internal block diagram
The adjacent diagram illustrates 4 logical, linked sub‑functions of the hinge switch.
Function f0 is a basic function and includes the monitoring of the power supply as well as internal, cyclical tests.
The task of function f1 is to evaluate the status of the device inputs, whereas function f2 checks the opening of the guard. Function f3 is intended to activate or deactivate the safety out‑ puts and check for any faults or short circuits in the outputs.
The safety‑related function, which combines the sub‑functions mentioned above, only activates the safety outputs if the input signals are correctly applied and the guard is in closed position.
The status of each function is displayed by the corresponding LED (PWR, IN, ACT, LOCK, OUT), in such a way that the general device status becomes immediately obvious to the operator.
Series connection
To simplify series connections of the devices, various M12 connectors are available that allow complete wiring.
This solution significantly reduces installation times while at the same time maintaining the maximum safety levels PL e and SIL 3.
