Why Choose the Pizzato NSG4SE1SMK-F41 Safety Interlock Switch?
The Pizzato NSG4SE1SMK-F41 is a high-security RFID safety interlock switch with guard locking designed for advanced industrial machine safety applications. As part of the robust Pizzato NS NS-series safety locking switch platform, it delivers secure actuator recognition, electromechanical guard locking, and reliable safety feedback for automated machinery systems.
This model features 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 industrial environments requiring high functional safety performance and compliance with modern machine safety standards.
With its rugged technopolymer housing, compact form factor, and high ingress protection rating, the NSG4SE1SMK-F41 is ideal for robotic cells, packaging systems, conveyors, and OEM machinery requiring reliable guard locking and safety monitoring.
Key Advantages
- High-security RFID-coded actuator system (F41 coding level) for strong anti-tamper protection.
- Solenoid guard locking mechanism with fail-safe de-energised release principle.
- Dual-channel safety outputs (OS1/OS2) for redundant monitoring.
- Integrated diagnostic signals for actuator and lock status (O3/O4).
- Complies with EN ISO 14119 machine safety requirements.
- Suitable for high-performance industrial automation systems with series connection capability.
Key Features
- Pizzato NS-series RFID safety interlock switch.
- Model: NSG4SE1SMK-F41.
- High-level coded RFID actuator (F41).
- De-energised solenoid guard locking (fail-safe design).
- M12 12-pole industrial connector interface.
- Safety outputs OS1/OS2 with diagnostic outputs O3/O4.
- Front auxiliary release for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSG4SE1SMK-F41 ensures machinery can only operate when protective guards are correctly closed and locked. When the RFID-coded actuator is detected and the locking system is engaged, the safety outputs enable controlled machine operation.
If the guard is opened or the locking condition is removed, the system triggers an immediate safe stop. Integrated diagnostics continuously monitor actuator status and lock condition, supporting safe 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.
