NG series safety switches with solenoid and RFID technology Maximum safety with a single device Description These switches are used on machines where the hazardous conditions remain for a while, even after the machines have been switched off, for example because of mechanical inertia of pulleys, saw disks, parts under pressure or with high temperatures. They can also be used when it is necessary to control machine guards allowing the opening of protections only under specific conditions. Constructed with redundant electronic technology, the NG series switches make it possible to create...

Six LEDs for immediate diagnosis As the LEDs have been designed for quick immediate diagnosis, the status of each input and output is highlighted by one specific LED. This makes it possible to quickly identify the interruption points in the safe chain, which device is released, which door is opened and any errors inside the device. All that in a straightforward way without needing to decode complex blinking sequences. Double anti-tampering safety Each NG series actuator is supplied with four stainless steel tamper-proof screws, for it to be fitted on the protection. Four protection insert...

Complete safety system The use of complete tested solutions means that the customer can be certain of the electrical compatibility between the NG series switch and Pizzato Elettrica safety modules, thus ensuring greater reliability. In fact, these sensors have been tested for operation with the modules specified in the table shown on the side. Once their compatibility has been verified, all NG series safety switches can generally be connected to safety modules or safety PLCs recognising OSSD input signals. The NG series switch can be used individually, prior evaluation of the safe outputs...

Actuation sequence in mode 1 The switch is supplied with power (PWR LED on, green), the IS1 and IS2 inputs are enabled (IN LED on, green), the OS1 and OS2 safety outputs are disabled (OUT LED off). The actuator is on the outside of the activation zone (LED ACT off). When the actuator is brought inside the safe activation area (dark grey area), the switch turns on the ACT LED (green). In this position, the O3 door-closed signalling output is activated. The actuator is not locked (LOCK LED off). The I4 input can be used to lock the actuator (LOCK LED on, green). The OS1 and OS2 safe outputs...
