Why Choose the Pizzato NSE3ZZ1SQK-F41 Safety Locking Switch?
The Pizzato NSE3ZZ1SQK-F41 is a compact and highly reliable RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. It is part of the proven Pizzato NS series safety locking switch family, engineered to deliver secure guard monitoring, actuator detection, and controlled access in demanding industrial environments.
This device ensures that protective guards remain locked during hazardous machine operation and only release when safe conditions are confirmed. Its RFID-coded actuator system provides strong anti-tamper protection, while the integrated solenoid locking mechanism ensures safe and controlled access to machine doors and safety enclosures.
The NSE3ZZ1SQK-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 machine architecture.
This model uses the 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 or lower-level coding systems such as F40 variants. Based on NS-series architecture, it is designed for high-security industrial safety applications in modern automation systems.
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).
- Compact industrial design suitable for tight machine installations.
- Supports integration into multi-device safety chains.
Key Features
- Pizzato NS series safety locking switch.
- Model: NSE3ZZ1SQK-F41.
- RFID high-level coded actuator system (F41 coding).
- Solenoid locking mechanism for controlled guard access.
- Industrial-grade thermoplastic housing construction.
- IP67 / IP69K protection rating for harsh environments.
- Compact actuator-switch safety architecture for OEM machinery.
The NSE3ZZ1SQK-F41 ensures that machine guards cannot be opened while hazardous motion is active. 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 flexible integration into complex safety systems, supporting multi-device safety chains while maintaining high diagnostic coverage and reliability.
