These safety 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. All products (except FW series) are equipped with a particular mechanical hooking that does not allow the separation of the head from the body during its positioning. Rotating heads Removing the two fastening screws, in all switches, the head can be rotated in 0 steps. Actuator regulation zone 0,5... 4,5 mm This switch has a wide backlash of the actuator into the head (4 mm) for an easier installation. With closed door, check that the actuator doesn t knock straight against the head of the switch; it must be in the adjustment zone (0,5 4,5 mm) Versions with N actuator extraction force Versions with N actuator holding force instead of the standard 10 N are available. Not detachable head The action head type is completely interchangeable and compatible with previous head type, but it has the advantage to be not detachable from the switch body even if it is always adjustable in 0 steps (Pizzato Elettrica patent). The new head is safer because it cannot be ruined during installation. The head fixing screws have been reduced to only two (instead of the previous four) and so the rotation operation will be quicker and cheaper. Safety screws for actuators These new screws have tamper-resistant Torx buttonheads. Devices fixed with this kind of screws cannot be removed or tampered by common tools. See accessories page 6/5. Installation examples Limits of utilization Do not use where dust and dirt may penetrate in any way into the head and deposit there, in particular where metal dust, concrete or chemicals are spread. Do not use where explosive or inflammable gas is present. Use Atex products in environments with explosion hazard (see page /17).
