NG 2D5D41AR-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D5D41AR-F31 Safety Switch?

The Pizzato NG 2D5D41AR-F31 is an advanced RFID safety switch with guard locking and integrated control devices designed for monitoring and securing movable guards, doors and access points on industrial machinery. As part of the Pizzato NG series, it combines high-level coded actuator detection, electronic safety outputs and robust mechanical guard locking within a compact metal housing.

Designed for demanding machine safety applications, the NG 2D5D41AR-F31 uses a high coding level RFID actuator to provide dependable guard detection and improved protection against deliberate or accidental bypassing. Integrated control devices allow operator functions to be incorporated directly into the safety switch assembly, helping simplify machine layouts and reduce the number of separate control components required around guarded areas.

This model uses the D working principle, keeping the actuator locked while the solenoid is de-energised. It incorporates a rotating head with key-operated auxiliary release, electronic safety inputs and outputs, signalling outputs for actuator and lock status, and is supplied with the VN NG-F31 high-coded actuator. The rugged metal housing and IP65 protection rating make it suitable for industrial machinery and automated production environments.

Reliable Guard Locking for Industrial Automation

Safety switches with guard locking are used where machinery must remain inaccessible until hazardous movement or processes have stopped. The Pizzato NG series combines RFID actuator recognition with electronic safety outputs and a high-strength locking mechanism, allowing machine control systems to monitor both the position and locked condition of a guard.

The NG 2D5D41AR-F31 also incorporates control devices directly into the switch assembly, helping machine designers create compact operator stations around access doors and guarded areas. Its electronic architecture supports integration with modern safety PLCs and controllers, while dedicated diagnostic outputs provide clear feedback on actuator and locking status.

Typical Applications

• Industrial machine guard doors and access panels.
• Automated production and assembly machinery.
• Robotic cells and guarded automation systems.
• Packaging and processing equipment.
• Conveyor and material handling machinery.
• CNC and machine-tool guarding.
• OEM machinery requiring integrated safety and operator controls.
