Why Choose the Pizzato NSH4ZZ1DB2-F41 Safety Locking Switch?
The Pizzato NSH4ZZ1DB2-F41 is a high-integrity RFID safety interlock switch with solenoid locking designed for machine guarding applications in advanced industrial automation systems. As part of the Pizzato NS series safety locking switch family, it provides secure guard locking, actuator detection, and reliable safety monitoring for modern machinery environments.
This model ensures that protective guards remain locked during hazardous machine operations and only allow access when safe conditions are confirmed. Its RFID-coded actuator system delivers strong anti-tamper protection, while the integrated solenoid locking mechanism ensures controlled access to safety doors and machine enclosures.
The NSH4ZZ1DB2-F41 is widely used in OEM machinery and automated production systems requiring high functional safety, diagnostic feedback, and compliance with international standards such as ISO 14119. It is suitable for safety architectures up to PL e / SIL 3 depending on system design.
This variant belongs to the NS Mode 2 operating family, featuring an energised solenoid locking principle combined with a high-level coded F41 RFID actuator, meaning only a uniquely matched actuator can operate the switch, significantly improving tamper resistance and safety integrity.
Key Advantages
- High-security RFID-coded machine safety interlock system.
- Energised solenoid locking ensures controlled guard access.
- F41 high-level coding provides strong anti-tamper protection.
- Designed for integration into PL e / SIL 3 safety systems (system dependent).
- Robust industrial housing for harsh environments.
- Supports series connection in safety control architectures.
Key Features
