Safety Switches NG Series

Pizzato Elettrica presents the NG Series RFID safety switches with block keep on developing: which guarantee a higher versatility and increase the possibilities of application. The Customer has the opportunity to choose between two different activation modes of the safety outputs: active with guard closed and locked (Mode 1) for machines with inertia, or active with guard closed and unlocked (Mode 2) for machines without inertia. Some of the new models are provided with EDM (External Device Monitoring): the switch automatically checks the correct functioning of external devices connected to the safety outputs as relays or contactors, providing a feedback signal at the EDM input verifying the coherence between EDM signal and state of the safety outputs. Pizzato Elettrica introduces also non-reprogrammable version: suitable for applications where customers require a device preventing the reprogramming of the associated actuator and switch, All models of NG series have been certified by the third party organization TÜV SÜD for being implemented in applications up to SIL 3, PL e and cat.4.
