Why Choose the Pizzato NSG4SE1SMK Safety Interlock Switch?
The Pizzato NSG4SE1SMK is a high-performance RFID safety interlock switch with guard locking designed for advanced industrial machine safety applications. As part of the Pizzato NS NS-series safety locking switch family, it provides secure actuator recognition, robust solenoid locking, and reliable safety signal monitoring for automated machinery systems.
This model uses a de-energised solenoid locking principle combined with high-level RFID coding (F41), ensuring strong protection against tampering and guaranteeing that machine guards remain locked during hazardous operating conditions. It is engineered for demanding industrial environments where safety integrity and compliance are essential.
With its rugged technopolymer housing, compact industrial design, and IP-rated protection, the NSG4SE1SMK is widely used in robotic cells, packaging systems, conveyors, and OEM machinery requiring certified guard locking and high-reliability safety interlocking.
Key Advantages
- High-security RFID-coded actuator system (F41 coding level) for strong anti-tamper protection.
- Integrated solenoid guard locking mechanism for safe access control.
- Dual-channel safety outputs (OS1/OS2) for redundant monitoring.
- Real-time status feedback for actuator insertion and lock condition (O3/O4 signals).
- Complies with EN ISO 14119 machine safety standards.
- High durability for harsh industrial environments.
Key Features
- Pizzato NS-series safety interlock switch with locking.
- Model: NSG4SE1SMK.
- RFID-coded actuator recognition (F41 high coding level).
- De-energised solenoid guard locking (fail-safe principle).
- M12 12-pole industrial connector interface.
- Safety outputs OS1/OS2 with diagnostic outputs O3/O4.
- Auxiliary release function for maintenance and emergency access.
Reliable Machine Guarding and Safety Control
The Pizzato NSG4SE1SMK ensures machinery only operates 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 machine operation under controlled conditions.
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 systems in industrial automation.
Typical Applications
- Robotic safety cell enclosures.
- Industrial automation machinery.
- Packaging and production equipment.
- Conveyor and material handling systems.
- OEM machine building applications.
- Safety-critical industrial environments.
