Why Choose the Pizzato NSH4ZZ1SMK Safety Locking Switch?
The Pizzato NSH4ZZ1SMK is a high-reliability RFID safety interlock switch with solenoid locking designed for advanced machine guarding applications in industrial automation systems. It belongs to the robust Pizzato NS series safety locking switch family, engineered to ensure secure guard monitoring, actuator detection, and controlled access in demanding industrial environments.
This device ensures that machine guards remain locked during hazardous operation and only unlock when safe conditions are confirmed. Its RFID-based actuator recognition system provides strong anti-tamper protection, while the integrated solenoid locking mechanism ensures safe and controlled access to machine doors and safety enclosures.
The NSH4ZZ1SMK 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 “H working method” configuration, which uses an energised solenoid locking system (power-to-lock principle) and supports Mode 2 safety logic, where safety outputs remain active with closed and secured guards. This architecture is designed for machines requiring controlled access with continuous guard monitoring and high diagnostic coverage. Based on the NS series design, it supports redundant safety inputs and outputs for reliable industrial integration.
Key Advantages
- High-security RFID-coded safety interlock system for machine guarding.
- Solenoid locking ensures guards remain secured during hazardous operation.
- Reliable actuator detection with anti-tamper protection.
- Designed for integration into PL e / SIL 3 safety systems (system dependent).
- Industrial-grade technopolymer housing for harsh environments.
- Supports series connection in complex safety architectures.
Key Features
- Pizzato NS series safety locking switch.
- Model: NSH4ZZ1SMK.
- RFID safety actuator recognition system.
- Solenoid locking mechanism (power-to-lock principle).
- 2 safety inputs (IS1–IS2).
- 2 safety outputs (OS1–OS2).
- Signal outputs for actuator insertion and lock status.
- M12 12-pin connector interface.
- IP67 / IP69K protection rating for harsh industrial environments.
Reliable Machine Safety Performance
The NSH4ZZ1SMK ensures that machine guards cannot be opened while hazardous motion is active. Its RFID-coded system prevents actuator substitution, while the solenoid locking mechanism ensures controlled access only under safe conditions, improving operator protection in automated environments.
The NS series architecture allows multiple safety devices to be connected in series while maintaining high diagnostic coverage and safety integrity, making it suitable for complex industrial machine safety systems.
Typical Applications
- Industrial machine guarding systems.
- Robotic safety cells.
- Automated production lines.
- Packaging and processing machinery.
- Conveyor safety doors and access panels.
- OEM machinery requiring reliable safety interlocking.
