Why Choose the Pizzato NG 2D1D415H-F31 Safety Switch with Lock?
The Pizzato NG 2D1D415H-F31 is an advanced NG series safety switch with guard locking and integrated control devices, designed for monitoring and securing movable guards, doors and access points on industrial machinery. It combines electronic safety monitoring, a robust locking mechanism and three integrated operator-control devices in a durable metal housing.
The switch uses Pizzato's D working principle, in which the actuator is locked while the electromagnet is de-energised. It provides two IS1-IS2 safety inputs and two OS1-OS2 safety outputs, with safety-output activation mode 1 making the outputs active when the actuator is inserted and locked. Dedicated O3 and O4 signalling outputs separately indicate actuator-inserted and actuator-locked status.
The NG 2D1D415H-F31 is supplied complete with the VN NG-F31 high-coding-level actuator. Its integrated operator devices comprise a two-position key selector with 1NO contact, a green pushbutton with 1NO contact and a red turn-to-release emergency stop button with 2NC contacts. The locking system provides a substantial 9750 N holding force, making this configuration well suited to demanding industrial machine-guarding applications.

Integrated Guard Locking and Operator Safety Control
Safety switches with guard locking are used where access to hazardous machinery must remain restricted until moving components, stored energy or other hazards have reached a safe condition. The Pizzato NG series combines coded actuator monitoring with electronic safety outputs and electromechanical locking, allowing both guard position and locking status to form part of the machine's safety-related control system.
The NG 2D1D415H-F31 also consolidates important operator functions at the guarded access point. Its two-position key selector and green pushbutton provide local control inputs, while the red turn-to-release emergency stop button provides two normally closed contacts for emergency-stop circuitry. Dedicated O3 and O4 outputs provide separate actuator-inserted and actuator-locked status signals for machine control and diagnostics.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and safeguarded automation areas.
- Automated manufacturing and assembly machinery.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Machine tools and automated production equipment.
- Production cells requiring local emergency-stop and operator controls.
- Applications requiring high-coding-level guard monitoring and robust guard locking.
