Why Choose the Pizzato NG 2D1D512P Safety Switch with Lock?
The Pizzato NG 2D1D512P is an advanced RFID safety switch with guard locking and integrated control devices designed for monitoring and securing protective guards, doors and access points on industrial machinery. Part of the Pizzato NG series, this exact configuration combines electronic safety monitoring, high-strength guard locking and two local operator pushbuttons within a robust metal housing.
This model uses the D working principle, meaning the actuator is locked while the solenoid is de-energised. It provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, an O3 signalling output for actuator-inserted status, an O4 signalling output for actuator-locked status, I4 or IE1–IE2 solenoid activation inputs, an I3 actuator programming/reset input and an I5 EDM feedback input. Mode 1 operation activates the safety outputs when the actuator is inserted and locked.
The NG 2D1D512P incorporates two integrated operator controls, comprising a white 1NO pushbutton in position 1 and a blue 1NO pushbutton in position 2. This version is supplied without an actuator and without a connector, allowing the appropriate actuator and connection arrangement to be selected separately for the machine installation.
Key Advantages
- Combines RFID guard monitoring, guard locking and two integrated pushbuttons within one assembly.
- White 1NO pushbutton provides a local operator command at the guarded access point.
- Blue 1NO pushbutton provides a second independent operator command.
- 9,750 N maximum holding force supports secure retention of protective machine guards.
- De-energised locking principle keeps the actuator locked while the locking solenoid is not energised.
- Mode 1 safety logic requires the actuator to be inserted and locked before the safety outputs become active.
- Dedicated O3 and O4 outputs provide separate actuator-inserted and actuator-locked status information.
- I5 EDM feedback input supports monitoring of external downstream switching devices.

Reliable Guard Monitoring and Operator Control for Industrial Machinery
The Pizzato NG 2D1D512P combines electronic guard monitoring with mechanical guard locking and redundant safety signals for integration into modern machine safety systems. Its Mode 1 configuration requires the actuator to be both inserted and locked before OS1 and OS2 become active, while O3 and O4 separately communicate actuator insertion and locking status to the control system.
The integrated white and blue 1NO pushbuttons provide two local operator commands directly at the guarded access point, helping reduce the need for a separate control station. The additional I5 EDM feedback input enables external device monitoring, making this configuration particularly useful in safety architectures where the state of downstream contactors or switching devices must be supervised.
Typical Applications
- Machine guard doors and protective access panels.
- Automated production and assembly machinery.
- Robotic cells and safeguarded manufacturing areas.
- Packaging and processing equipment.
- Conveyor and material handling systems.
- Machine tools and automated manufacturing equipment.
- Industrial machinery requiring guard locking, integrated operator controls and EDM feedback monitoring.
