Why Choose the Pizzato NG 2D7D415D Safety Switch with Lock?
The Pizzato NG 2D7D415D is an industrial NG series safety switch with guard locking and integrated control devices designed for safety-related monitoring of movable machine guards, doors and access points. It combines coded electronic guard detection, high-strength mechanical locking and local operator controls in a robust metal housing.
This configuration uses principle D operation, meaning the actuator is locked when the solenoid is de-energised. Its electronic architecture provides two safety inputs IS1–IS2, two safety outputs OS1–OS2 and dedicated O3 and O4 signalling outputs for actuator-inserted and actuator-locked status, allowing the machine safety system to supervise both guard position and locking condition.
The NG 2D7D415D features three integrated control devices: a white pushbutton with 1NO + 1NC contacts, a black pushbutton with 1NO + 1NC contacts and a red turn-to-release emergency pushbutton with 2NC contacts. This base configuration is supplied without actuator and without connector, allowing the appropriate actuator and connection arrangement to be selected separately for the installation.
Key Advantages
- Combines guard monitoring, guard locking and three integrated operator controls in one assembly.
- High 9750 N locking force provides robust mechanical guard retention.
- Principle D operation retains the actuator when the locking solenoid is de-energised.
- Integrated white and black 1NO + 1NC pushbuttons provide local machine-control functions.
- Integrated red emergency pushbutton with 2NC contacts provides a dedicated emergency control.
- Two safety inputs and two safety outputs support electronic safety-system integration.
- Separate O3 and O4 outputs provide actuator-inserted and actuator-locked status information.
- Rotating head with escape pushbutton supports personnel egress from guarded machine areas.

Reliable Guard Locking and Integrated Machine Control
The Pizzato NG 2D7D415D is designed for machinery where a protective guard must remain secured until hazardous conditions have ended. Its 9750 N locking force provides substantial mechanical retention, while the electronic safety architecture allows the control system to monitor actuator presence and locking status independently.
Three integrated control devices place normal operator commands and an emergency function directly at the protected access point. Combined with the rotating escape-release head, Mode 1 safety-output activation and de-energised locking principle, the NG 2D7D415D provides a comprehensive guard-management solution while allowing the required actuator to be selected separately.
Typical Applications
- Robotic cells and automated production areas.
- Machine guard doors and safety access gates.
- Packaging and processing machinery.
- Automated assembly and manufacturing equipment.
- Machine tools and machining centres.
- Conveyor and material handling installations.
- Guarded machinery requiring local controls and emergency functionality.
