The company Pizzato Elettrica is suggesting to the market many new products in the safety field for the factory automation.
In particular, it has been recently introduced anew and innovative series of strong protective switches with separate industrial actuator and manufacturers of solenoid for guards and entrance machinery monitoring.
These FG series switches have a shape suitable for the installation also on modular profiles (40x40 mm) and distinguish themselves for following features:
• High sturdiness guaranteed by the metal housing and the stainless steel actuator (holding force 2500 N)
• Contact blocks with 4 poles available in 12 different configurations.
• Possibility of operation state signalling through external LED.
• Rotating head in 90° steps, not detachable, with actuator entries both frontal and vertical for the maximum versatility in the installation
• Protection degree IP67
• Versions with rotating lock release device, with emergency release push button or with both devices.
The new switches series integrates the wide range of products that Pizzato Elettrica can offer to its customers, for complete solutions and without compromise to machinery safety problems.

Omron STI safety interlock switches are available in a wide variety of models to satisfy most machine guarding applications. Models range from rope-operated emergency stop buttons, non-contact magnetic and hinge-pin-operated interlocks, to solenoid-actuated guard-door locking switches that restrict access until industrial safe conditions exist. All models conform to applicable U.S. safety standards and all carry the CE mark.
These safety switches are suitable for hinged safety guards, which need to be closed to ensure the necessary operational security.
The variety of requirements to be found in practice can be met by means of the wide range of safety switches for hinged guards.
Depending on the particular version of the switches, small professional doors and service flaps as well as heavy hinged doors on engineering machines and plants can be protected in such a way as to provide for easy setting up and maintenance.
Design and mode of operation:
A general advantage of the safety switches shown here is the integral cam within the safety switch. The requirements of EN 1088, such as positive linkage between cam and supplier of actuator as well as protection against tampering are thus fulfilled.
This combination within the switch provides cost advantage for the user in avoiding the necessity of mounting a specially designed cam.
These safety switches are mounted with slow action.
Protection class of all the safety switches is IP 67
The FailSafe GuardSwitch is designed as a safety interlock to be attached to a machine's guard or door. Unlike a standard reed switching interlock, the circuit has been designed to have an "open" failure mode. If the main reed sticks closed when the guard opens, the in-line industrial fuse will blow, opening the circuit. If the watchdog reed sticks closed when the guard closes, the in-line fuse will blow, opening the circuit. The circuit will draw up to 4.5A to blow the fuse in less than 200ms. Along with being FailSafe, all the 200 series switches have non-coded actuators suppliers.
The 100 Series are non-contact interlock position switches with switching voltage models available up to 250 Volts. There are many models to fit a wide variety of applications.
Idem Guardian Line Safety Rope Switches are designed to be mounted on machines and sections of conveyors manufacturers which cannot be protected by guards. In contrast to traditional mushroom-head emergency stop buttons, Safety Rope Switches can initiate an emergency command from any point along the installed rope length and provide robust Emergency Stop Rope Pull protection for exposed conveyors or machines.
On pulling the rope, the safety contacts are positively opened and the auxiliary contact are closed. The switches are mechanically latched and can then only be returned to the operational condition by pressing the blue reset button (as required by EN418). A bi-colour Led readout is available to enable switch status to be viewed from a distance.
Satisfies EN 418 and IEC 947-5-1 IEC 947-5-5

One of the areas which makes Idem's Guardian Line Rope Switch Line new and innovative is in the area of rope connectivity. Traditional ‘turnbuckle’ style rope professional fasteners and adjusters are prone to rope slippage and require frequent re-tensioning leading to production loss caused by machine down time.Idem has overcome this common problem by providing a ‘no nuts or bolts specifications’ rope connection system with a ‘Quick Link’ clasp at one end of the rope and a patented Tensioner /Gripping pliers at the other.
The Tensioner / Gripper is located at the switch (rather than elsewhere along the rope length) so that the switch tension window can be viewed.
Final setting and locking can be achieved in a matter of seconds without any need for frequent re-tensioning.
