Why Choose the Pizzato NSG4SR1SMK-F41 Safety Interlock Switch?
The Pizzato NSG4SR1SMK-F41 is a high-performance RFID safety interlock switch with guard locking designed for demanding industrial machine safety applications. It belongs to the advanced Pizzato NS NS-series safety locking switch platform, offering secure actuator recognition, robust solenoid-based locking, and reliable safety signal feedback for automated machinery systems.
This model uses a de-energised solenoid locking mechanism combined with high-level RFID coding (F41), ensuring strong protection against tampering and guaranteeing that machine guards remain securely locked during hazardous operation. It is engineered for safety-critical environments where compliance with EN ISO 14119 and high functional safety performance are required.
With its rugged technopolymer housing, compact industrial footprint, and IP67/IP69K protection rating, the NSG4SR1SMK-F41 is widely used in robotic cells, packaging machinery, conveyors, and OEM automation systems requiring certified guard locking and safety monitoring.
Key Advantages
- High-security RFID-coded actuator system (F41 high coding level) for strong anti-tamper protection.
- Solenoid guard locking with fail-safe de-energised release principle.
- Dual-channel safety outputs (OS1/OS2) for redundant monitoring of guard status.
- Integrated diagnostic outputs for actuator insertion and lock status (O3/O4).
- Complies with EN ISO 14119 machine safety standards.
- Designed for integration into PL e / SIL 3 safety architectures in industrial automation systems.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSG4SR1SMK-F41.
- RFID-coded actuator recognition (F41 high coding level).
- De-energised solenoid guard locking (fail-safe design).
- M12 12-pole industrial connector interface.
- Safety outputs OS1/OS2 with diagnostic outputs O3/O4.
- Integrated auxiliary release for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSG4SR1SMK-F41 ensures machinery only operates when protective guards are correctly closed and locked. When the RFID-coded actuator is detected and locking is engaged, the safety outputs enable controlled machine operation under safe conditions.
If the guard is opened or the locking condition is removed, the system triggers an immediate safe stop. Continuous diagnostics monitor actuator status and lock condition, supporting integration into PLC-based safety architectures in industrial automation systems.
Typical Applications
- Robotic safety cell enclosures.
- Industrial automation machinery.
- Packaging and production systems.
- Conveyor and material handling equipment.
- OEM machine building applications.
- Safety-critical industrial environments.
