Why Choose the Pizzato NSH4ZZ1SA2-F41 Safety Locking Switch?
The Pizzato NSH4ZZ1SA2-F41 is a high-reliability RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. It belongs to the advanced Pizzato NS series safety locking switch family, providing secure guard monitoring, actuator recognition, and controlled access for modern machinery.
This device ensures that protective guards remain locked during hazardous machine operation and only release when safe conditions are confirmed. Its integrated RFID-coded actuator system provides strong anti-tamper protection, while the solenoid locking mechanism ensures safe and controlled access to machine doors and safety enclosures.
The NSH4ZZ1SA2-F41 is widely used in OEM machinery, robotics systems, packaging equipment, and automated production lines requiring functional safety, diagnostics, and compliance with ISO 14119 machine safety standards. It can be integrated into safety architectures up to PL e / SIL 3 depending on system design.
This model uses an F41 high-level coded RFID system, meaning each actuator is uniquely coded and must be paired with the switch. This provides maximum anti-tamper protection compared to shared-code systems such as F40, making it suitable for high-security industrial environments.
Key Advantages
- High-security RFID-coded safety interlock system for machine guarding.
- Solenoid locking ensures guards remain secured during hazardous operation.
- F41 unique coding provides maximum anti-tamper protection.
- Designed for integration into PL e / SIL 3 safety systems (system dependent).
- Robust industrial housing for demanding environments.
- Supports series connection in safety control chains for complex machines.
Key Features
- Pizzato NS series safety locking switch.
- Model: NSH4ZZ1SA2-F41.
- RFID high-level coded actuator system (F41 coding).
- Solenoid locking mechanism for controlled guard access.
- Technopolymer industrial housing construction.
- IP67 / IP69K protection rating for harsh environments.
- Mode 2 operating principle (locked actuator with energised solenoid).
Reliable Machine Safety Performance
The NSH4ZZ1SA2-F41 ensures that machine guards cannot be opened during hazardous operation. Its RFID-based identification prevents actuator substitution, while the solenoid lock ensures controlled access only under safe conditions, improving operator safety in automated industrial environments.
The NS series architecture allows multiple safety devices to be connected in series, enabling efficient integration into complex machine safety systems while maintaining high reliability and compliance.
Typical Applications
- Industrial machine guarding systems.
- Automated production lines.
- Robotics safety enclosures.
- Packaging and processing machinery.
- Conveyor safety doors and access panels.
- OEM machinery safety integration.
