Why Choose the Pizzato NG 2D7D411A-LP50 Safety Switch with Lock?
The Pizzato NG 2D7D411A-LP50 is an NG series RFID safety switch with guard locking, designed for monitoring movable machine guards and controlling access to hazardous areas. It combines non-contact coded actuator detection, electronically monitored guard locking and OSSD safety outputs in a robust metal housing for industrial machinery and automation systems.
This model uses the D working method, meaning the actuator is locked when the solenoid is de-energised. It provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, an O3 signalling output for actuator-inserted status and an O4 signalling output for actuator-locked status. Mode 1 operation activates the safety outputs when the actuator is inserted and locked.
The LP50 option identifies an extended anti-panic release pushbutton configuration suitable for installations with a maximum wall thickness of 50 mm. The NG 2D7D411A-LP50 has a rotating head with escape pushbutton, three threaded M20 × 1.5 conduit entries and IP67 / IP69K environmental protection. This configuration is supplied without an actuator, allowing the appropriate compatible Pizzato NG actuator to be selected separately.
Key Advantages
- Combines RFID guard monitoring and monitored guard locking in one safety device.
- LP50 extended escape release supports installations with wall thicknesses up to 50 mm.
- D working method keeps the actuator locked when the solenoid is de-energised.
- Two OSSD safety outputs facilitate integration with compatible safety controllers and safety PLCs.
- Separate O3 and O4 outputs provide guard-position and lock-status signalling.
- Robust metal housing with three M20 × 1.5 conduit entries.
- IP67 and IP69K protection supports installation in demanding industrial environments.
- Supplied without actuator, allowing selection of a compatible F30 or F31 actuator to suit the required coding level.

RFID Guard Locking with an Extended Escape Release
The Pizzato NG series is designed for machinery where a movable guard must be monitored and, where required by the safety system, remain locked while hazardous conditions persist. RFID technology provides non-contact coded actuator detection, while the electronic safety architecture enables the guard and locking condition to be evaluated through compatible safety-related control equipment.
The NG 2D7D411A-LP50 combines Mode 1 lock monitoring with an anti-panic escape pushbutton. The LP50 option extends the release-button arrangement for installations through walls or guarding structures up to 50 mm thick, making this configuration particularly useful where personnel may need an escape-release facility from inside a guarded area.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells with personnel-access doors.
- Automated production and assembly areas.
- Packaging and processing machinery.
- Machine tools with residual hazardous movement.
- Conveyor and material handling systems.
- Guarded areas requiring an internal anti-panic escape release.
- OEM machinery and industrial automation systems.
