3 These safety switches are ideal for controlling gates, sliding doors and other guards which protect dangerous parts of machines without inertia. 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. Orientable heads Removing the two fastening screws, in all switches, the head can be rotated in 0 steps. In this way it is possible to actuate the switch from 5 different directions. Wide-ranging actuator travel 0,5... 4,5 mm The head of this switch is equipped with an actuator with a wide range of travel. In this way the guard can oscillate along the direction of insertion (4mm) without causing unwanted machine shutdowns. This extensive travel is available in all actuators, in order to ensure maximum device reliability. Not detachable head To make head adjustment safer and smoother, these switches are equipped with a special head to body coupling system. This system makes it impossible to remove the head from the device even during adjustment, thus rendering the use of oneway screws unnecessary for locking the head in position once adjustment is complete. This solution is available for the LR, LX and LK series. Versions with N actuator extraction force Versions with N actuator holding force instead of the standard 10 N are available. Protection degree IP67 These devices are designed to be used in the toughest environmental conditions and they pass the IP67 immersion test acc. to IEC 605. They can therefore be used in all environments where the maximum protection of the housing is required. Safety screws for actuators As required by EN ISO 1411, the actuator must be fixed immovably to the door frame. Pan head safety screws with one-way fitting are available for this purpose. With this screw type, the actuators cannot be removed or tampered with using common tools. See accessories on page 5. Extended temperature range This range of switches is also available in a special version with an ambient operating temperature range of -ºC to +80ºC. They can be used for applications in cold stores, sterilisers and other devices with low temperature environments. Special materials that have been used to realize these versions, maintain unchanged their features also in these conditions, widening the installation possibilities. p
