Pizzato Elettrica has designed and patented new accessories to install the rope of protective switches faster and to obtain an aesthetically more pleasant system.
The new accessories, in comparison with the traditional fixing system through carpentry material, have the following advantages:
%u2022 The installation is faster because only one screw is used for the fastening of every rope extremity, and the parts are prepared to ease the installation. Some practical tests have pointed out that the installation time is halved, reason for which it is named FAST.
%u2022 The system is aesthetically pleasant, because thread parts (which sometimes tear operators%u2019 dresses) and the rope extremities, usually fixed by heat-shrinkable sheath or supplier of adhesive tape, have been hidden.
%u2022 The red plastic covers of the fixing parts have been developed also for the function of controlling the rope clamping. If the rope fastening screw is not fixed tightly enough, the cover cannot pass.
%u2022 The rope is fixed without folds, thus reducing the rope stabilisation time and the possible re-calibrations of the rope tightening.
Furthermore two sturdy pulleys has been introduced in applications where the rope is very long in order to support the rope length or to bend its route. They are designed to avoid any deformation and to allow the rope to remain in its industrial seat also when it is energetically activated. |

Command devices are of great importance for the man-machine interface in the area of industrial applications. For example, they are mounted in switch-boards, control panels, two-hand control panels, in lift manufacture and on materials-handling plants, including conveyors. Manual actuation of the devices starts operating sequences and functional processes or serves to bring these to an end.
Emergency stop command devices are generally connected in the safety circuit of a machine or plant and are of particular importance in terms of the control system for these. In case of a fault or accident, the secure function and quick accessibllity of Emergency Stop command devices can be crucial for saving life, limiting the degree of injury to personnel or the extent of damage to a machine.
New requirements are placed on the mode of operation of these command devices by the new harmonised European Standard EN 418 regarding functional aspects and recommendations for the arrangement of Emergency Stop equipment.

Safety coded magnetic sensor, SR-SM series
Pizzato Elettrica offers on the market the new safety magnetic sensor SR-SM series.
Safety magnetic sensors are devices studied to monitor protections and guards that, when linked to a safety module, can create a system up to safety category 4, according to EN 954-1. These products are composed by a magnetic field monitoring sensor, which is connected to the machine structure; and by a coded magnetic actuator, which has to be connected to the mobile guards. The sensor is manufactured to be activated only by the correct coded actuator and not through a common magnet.
Pizzato Elettrica safety sensors distinguish themselves by following main features:
• Insensitivity to dirt as totally sealed, making them especially proper to be used in the food-industry sector.
• Wide actuation zone, characteristic appreciated in the use of inaccurate protections or for protections that can change their mechanical characteristics through the time.
• Stainless steel fixing plates to avoid that the sensor could be damaged during the installation.
• Possibility of connection in series more sensors also with mechanical switches.
• Actuation from two different directions.
• Available with cable or M8 integrated manufacturer of connector.
• Actuators with operating distance of 5mm or 8 mm.
The new sensor series complete the wide range of products that Pizzato Elettrica can offer in the device safety field. For further information visit our web-site www.pizzato.com or ask for special documentation. |

SAFETY SWITCHES SUPPLIERS HINGE-SHAPED, PALLADIO LINE
Pizzato Elettrica widens the own range of products making a new series of safety switches hinge-shaped named Palladio, where thanks to an aimed planning and a punctual analysis of the market requirements, safety and style are melted in one single product. The switch is completely integrated in the mechanical hinge, to result practically invisible to an inexpert eye. This guarantees a higher safety because a switch hard to identify is consequently also more difficult to defeat.
The assembly without visible screws and the pleasant line, make the switch perfectly integrated also with guards of modern design machinery.
In order to complete the offer it’s available also an additional hinge with purely mechanics functions.
The innovation of the product regards also the technical aspects, as following:
• Several contact blocks up to 4 contacts (2 NC contacts + 2 NO contacts).
• Possibility of operating point regulation (fundamental for large guards).
• Protection degree IP67.
• Integrated cable or industrial connector output available from the frontal or the rear side. |

Manufacturer of safety switches FR series
Pizzato Elettrica switches of the FR series with separate industrial actuator reach the 4th generation. These switches are ideal for gates, protections, carter and all different guards which protect dangerous parts of a machine. The stainless steel actuator is fixed to the mobile section of the protection in order that every time the protection is opened the actuator is pulled out of the switch. A particular mechanism assures the positive opening of the electrical contacts by the pulling out of the actuator. These switches are easy to install and can be applied to any type of protection (hinged, sliding or removable). Furthermore the possibility of operating the switch only with the specific actuator assures that the machine can start again only when the guard is closed.
Pizzato Elettrica switches of the FR series distinguish themselves for the following characteristics:
• Rotating heads: by unscrewing the fixing screw the head can be rotated in 90° steps.
• Not detachable heads: the head “93” is perfectly interchangeable and compatible with the previous head “92” but it has the advantage that it is not detachable from the body, nonetheless it can rotate in 90° steps (Pizzato Elettrica patent). Practically speaking the new head is safer because it’s not possible to damage it during the installation.
The FR series complements the range of products that Pizzato Elettrica can offer to its customers. For further information, please visit the website www.pizzato.com or ask for the relative documentation. |

These protection switches are ideal to control gates, sliding doors and other guards protecting dangerous parts of machine. The stainless steel actuator is fastened to the moving part of the guard, so it is removed from the switch on every opening of the guard. The switch mechanism guarantees that removing the actuator forces the positive opening of the electrical contacts. Easy to install, these switches can be applied to any kind of protection (with hinge, sliding and removable ones). Besides, the possibility to actuate the switch only with its actuator guarantees that the machine can be restarted only when the guard has been closed.
- Polymer housing, three M20 or M16 knock out conduit entries
- Protection degree IP67
- 6 contact blocks available
- 8 stainless steel industrial actuators available
- 30 N actuator extraction force versions
- Silver contacts gold plated versions
- Cylindrical or slotted fixing holes
- Cover with hinged opening and with only one fixing screw. |

Application:
Safety switches with separate supplier of actuator are suitable for sliding, hinged and particularly removable safety guards, which need to be closed to ensure the necessary operational security. They are also suitable for professional fitting on profile sections and existing equipment.
In combination with safety control modules all safety switches with class 2 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
On the safety switches with class 2, the switching element is not physically connected to the actuator but functionally brought together or separated for switching. When the guarding device is opened, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
Schmersal make both standard and AS-i Safety at Work safety switches with separate actuator.
