6 F Switches with reset Switches with reset are safety appliances that guarantee the opening of the NC contact upon a single manoeuvre and its retention in that position with the locking head. This means that the activation of the switch will have no effect on the contact element until the reset button is pressed manually (the release or reset take place by pressing the blue reset button). The range is available for the E-2 series in both the thermoplastic and metal bodies, with metal head and IP66 protection degree. Both versions are available with two types of contact blocks, NO + NC and 2NC, with slow action and positive opening of the NC contact In conformity with standards IEC EN EN UNI EN 88 EN ISO 2- EN ISO 2-2 IEC 529 EN 6529 VDE 66-2 VDE Applications Escalators 4 Lifts F S D E E2 S D Fixing E E2 mm and 4/42 mm Lifting machines Thread Series part no.

16 F Key actuated switches The 5 way key actuated safety switches are used on gates, sliding doors and other devices to protect the access to dangerous parts of machines. The key is applied to the moving protection barrier so it has to be removed from the switch on every opening thus operating a positive opening of the NC contact. This kind of actuator is available on the E- E2 series with thermoplastic or metal body and thermoplastic head, with IP66 protection degree. In conformity with standards IEC EN EN UNI EN 88 EN ISO 2- EN ISO 2-2 IEC 529 EN 6529 VDE 66-2 VDE UNI EN 85 Applications Machines with safety barriers Safety for the operator The command circuit authorizing the start-up of the process is closed only by the complete insertion of the safety key, and the circuit is opened when this is removed. This prevents intentional tampering with the machine by the operator until the safety protection device is opened. Resistance to vibrations The device has been designed to permit limited key vibrations in case of mechanical disturbances.

20 F Pull wire switches Pull wire safety switches are essential for the continuous control of a long line of machines or parts extending over a considerable length. They guarantee the safety of the operator, who is able to control the immediate stop of the machinery from any point in the operating zone when no or few automatic systems to cut off the power supply are present. This kind of actuator is available on the series E-E2- E4 with thermoplastic or metal body and metal head, with IP66 protection degree. Applications In conformity with standards IEC EN EN UNI EN 88 EN ISO 2- EN ISO 2-2 IEC 529 EN 6529 VDE 66-2 VDE UNI EN 85 Long lines of machines: conveyor belts, textile machines, printing machines, etc Wire tension indicator For the exact cable tension, check that the notch on the drive shaft is in line with the head.

24 F Switches for hinges Safety switches for hinges are devices used to guarantee operator safety, applied to machines fitted with protection barriers. Metal shaft switches are ideal for the control of doors and gates, with application directly to the hinge. This kind of actuator is available on the series E with thermoplastic or metal body and metal head, with IP66 protection degree. In conformity with standards IEC EN EN UNI EN 88 EN ISO 2- EN ISO 2-2 IEC 529 EN 6529 VDE 66-2 VDE UNI EN 85 Applications Reduced angle of operation they guarantee stopping of dangerous movement when the lever reaches an angle of 4 '.
