Why Choose the Pizzato NS E4ZZ1SRK-N115 Safety Switch with Lock?
The Pizzato NS E4ZZ1SRK-N115 is an advanced RFID safety switch with electromagnetic guard locking and integrated control devices designed for machine guarding and industrial safety circuits. Part of the Pizzato NS series, it combines electronic guard monitoring, secure locking and operator controls within a robust technopolymer housing.
This configuration uses Principle E, meaning the actuator is locked when the electromagnet is energised, together with Mode 1 operation in which the OS safety outputs are active when the guard is locked. The switch provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, dedicated actuator and lock status outputs, two electromagnet activation inputs and a programming/reset input for integration with machine safety systems.
The N115 integrated control configuration provides two operator devices: a white 1NO pushbutton and a blue 1NO pushbutton. The switch has a maximum locking force of 2100 N, uses two M12 connectors for electrical connection and is supplied without an actuator, allowing a suitable compatible NS RFID actuator to be selected for the application.
Key Advantages
- Combines RFID safety monitoring, electromagnetic guard locking and operator controls in one device.
- Integrated white 1NO and blue 1NO pushbuttons reduce the need for separate control devices.
- Provides a substantial 2100 N locking force for secure machine guarding.
- Two safety inputs and two safety outputs support integration into safety circuits.
- Separate signalling outputs indicate actuator-inserted and actuator-locked conditions.
- Principle E power-to-lock operation locks the actuator when the electromagnet is energised.
- Dual M12 connector arrangement simplifies integration with machine wiring.
- Durable technopolymer construction with IP65 protection.

Integrated Guard Locking and Machine Control
Safety switches with guard locking are used where access to hazardous machine areas must be monitored and controlled as part of the machine safety system. The Pizzato NS series combines RFID actuator detection with electromagnetic locking, enabling the control system to monitor both guard position and lock status through dedicated safety and signalling outputs.
By incorporating two operator pushbuttons directly into the switch assembly, the NS E4ZZ1SRK-N115 can also provide convenient local machine controls at the guarded access point. This integrated approach can simplify machine design, reduce the number of separately mounted control components and provide operators with guard monitoring and control functions in a compact assembly.
Typical Applications
- Machine safety doors and movable guards.
- Robotic cells and automated production systems.
- Packaging and processing machinery.
- Assembly and manufacturing equipment.
- Conveyor and material handling systems.
- Machining centres and industrial production machinery.
- Guard stations requiring integrated operator pushbuttons.
- OEM machinery requiring RFID guard monitoring and controlled access.
