NS D4ST1SB2-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D4ST1SB2-F41 Safety Locking Switch?

The Pizzato NS D4ST1SB2-F41 is a robust RFID safety interlock switch with guard locking designed for monitoring and securing movable guards, doors and access points on industrial machinery. Part of the advanced Pizzato NS series, it combines electronic RFID actuator detection with electromagnetic locking to provide reliable guard monitoring for safety-related machine applications.

This configuration is supplied complete with a VN NS-F41 high-level coded RFID actuator, providing enhanced protection against actuator substitution. The switch incorporates 2 redundant OS safety outputs, an actuator-inserted signalling output, electromagnet activation inputs and a programming/reset input, allowing straightforward integration with compatible safety controllers and automated machine systems.

The NS D4ST1SB2-F41 operates according to principle D, meaning the actuator remains locked when the electromagnet is de-energised. It provides a substantial 2100 N holding force, an orientable front key-operated auxiliary release and IP67 / IP69K protection, making it suitable for demanding industrial guarding installations.

Key Advantages

• Combines RFID safety monitoring and electromagnetic guard locking in one device.
• Supplied with a VN NS-F41 high-level coded RFID actuator.
• High-level coding provides enhanced actuator identification and protection against substitution.
• 2100 N holding force provides secure retention of machine guards.

Reliable High-Level RFID Guard Monitoring and Locking

Safety interlock switches with guard locking are used where a protective guard must remain securely closed until hazardous machine conditions have ended. The Pizzato NS series combines electronic RFID actuator recognition with electromagnetic locking, enabling the safety system to supervise guard position while controlling access to hazardous areas.

The NS D4ST1SB2-F41 combines a high-level coded F41 actuator with principle D locking, retaining the actuator when the electromagnet is de-energised. Its redundant OS safety outputs provide safety-related status information, while the O3 output signals actuator insertion and the dedicated IE inputs control the electromagnet as part of the machine safety architecture.

Typical Applications

• Industrial machine guard doors and access panels.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production equipment.
• Conveyor and material handling systems.
• Machine tools and enclosed manufacturing equipment.
• Safety systems requiring high-level coded actuator identification.
