Why Choose the Pizzato NSD5ST1SMK-F41 Safety Interlock Switch?
The Pizzato NSD5ST1SMK-F41 is a high-reliability RFID safety interlock switch with solenoid locking designed for industrial machine guarding applications where access control and operator safety are critical. Manufactured by Pizzato Elettrica, it is part of the NS series safety switch family used across automation, robotics, and industrial machinery protection systems.
This device is typically mounted on safety doors, hinged guards, sliding panels, and machine access points. It ensures that hazardous machinery cannot operate while a guard is open, supporting compliance with EN ISO 14119 functional safety requirements.
The NSD5ST1SMK-F41 uses a high-level coded F41 RFID actuator system, meaning it recognises only a single uniquely paired actuator. This provides maximum protection against tampering and ensures the highest level of access control in safety-critical environments.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator for maximum tamper resistance.
- Designed for industrial machine safety and automation systems.
- Reliable dual-channel safety outputs for PLC integration.
- Integrated monitoring of guard position and locking status.
- Robust industrial design for harsh operating environments.
Key Features
- Pizzato NS series safety interlock switch with locking function.
- Solenoid locking mechanism with fail-safe de-energised release principle.
- High-level coded RFID actuator system (F41 type).
- 2 safety outputs (OS1–OS2).
- Actuator insertion and lock status monitoring outputs.
- ST configuration optimized for standard mounting and installation layouts.
- Industrial sealed housing suitable for harsh environments.
Advanced Machine Guard Safety Control
The NSD5ST1SMK-F41 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking mechanism prevents access until safe operating conditions are met, while the RFID system ensures only the correct F41-coded actuator can operate the switch.
This makes it suitable for high-integrity industrial environments where safety, reliability, and tamper resistance are essential. It integrates with safety PLCs to provide real-time monitoring of guard status and lock condition in automated systems.
Typical Applications
- Industrial automation production lines.
- Robotics safety cells and machine guarding systems.
- CNC machining centres and tooling equipment.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- Safety doors, guards, and access panels.
