Why Choose the Pizzato NSE4ZZ1SMK-F41 Safety Locking Switch?
The Pizzato NSE4ZZ1SMK-F41 is a high-performance RFID safety interlock switch with solenoid locking designed for advanced machine guarding in industrial automation systems. It belongs to the robust Pizzato NS series safety locking switch family, engineered to provide secure guard monitoring, actuator identification, and controlled access in high-risk industrial environments.
This device ensures that protective guards remain locked during hazardous machine operation and only release when safe conditions are confirmed. Its F41 high-level coded RFID system provides unique actuator pairing for maximum anti-tamper protection, while the integrated solenoid locking mechanism ensures reliable access control for machine doors and safety enclosures.
The NSE4ZZ1SMK-F41 is widely used in OEM machinery, robotics systems, packaging equipment, and automated production lines where functional safety and compliance with ISO 14119 machine safety standards are required. It can be integrated into safety systems up to PL e / SIL 3 depending on the overall system architecture.
This model belongs to the NS “M working principle” configuration, meaning it operates with a powered solenoid locking system (energised solenoid) and provides dual-channel safety monitoring outputs. According to the NS series architecture, Mode 3 operation enables differentiated safety output behaviour depending on actuator insertion and lock status, supporting advanced machine safety logic.
Key Advantages
- High-security F41 unique-coded RFID actuator system.
- Solenoid locking ensures guards remain secured during hazardous operation.
- Energised locking architecture for active safety control.
- Designed for integration into PL e / SIL 3 safety systems (system dependent).
- Robust industrial housing for harsh environments.
- High diagnostic capability with safety and status outputs.
Key Features
