NS D4CE1SA5-F40 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D4CE1SA5-F40 Safety Locking Switch?

The Pizzato NS D4CE1SA5-F40 is an advanced RFID safety interlock switch with solenoid guard locking designed for monitoring and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NS Safety Interlock Switches series, it combines coded actuator detection, electronic safety inputs and outputs, guard locking and diagnostic signalling in a robust technopolymer housing.

This model uses the D operating principle, with the actuator locked when the electromagnet is de-energised. In Mode 1, the OS safety outputs are active when the protective guard is locked. The switch provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, actuator-inserted and actuator-locked signalling outputs, two electromagnet activation inputs and a programming/reset input.

The NS D4CE1SA5-F40 is supplied complete with a low-level coded VN NS-F40 actuator. A front screwdriver-operated auxiliary release and rear escape release provide additional access functionality, while a locking force of 2100 N and IP67 / IP69K protection make the assembly suitable for demanding industrial machine-guarding installations.

Reliable RFID Guard Monitoring and Access Control

Safety locking switches are used where a protective guard must not only be monitored but also retained in the closed position until safe access can be permitted. The Pizzato NS D4CE1SA5-F40 combines RFID actuator recognition with electronic safety monitoring and a high-strength locking mechanism, providing an integrated solution for guarded industrial machinery.

The dedicated safety inputs, safety outputs and diagnostic signalling allow the switch to communicate guard and lock status to an appropriate safety control system. Its auxiliary and escape-release mechanisms provide additional functionality for machine access, while the robust environmental protection supports reliable use in demanding production environments.

Typical Applications

• Machine guard doors and protective access gates.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Assembly and material-handling equipment.
• Machinery requiring guard retention until hazardous movement has stopped.
• Industrial automation systems requiring monitored and controlled operator access.
