Why Choose the Pizzato NSE4ZZ1SMK-F40 Safety Locking Switch?
The Pizzato NSE4ZZ1SMK-F40 is a reliable RFID safety interlock switch with solenoid locking designed for machine guarding and operator safety in industrial automation systems. It belongs to the well-established 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 unlock when safe conditions are confirmed. Its RFID-coded actuator system provides dependable anti-tamper protection, while the integrated solenoid locking mechanism ensures safe and controlled access to machine doors and safety enclosures.
The NSE4ZZ1SMK-F40 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 overall system architecture.
This model uses the F40 low-level coded RFID actuator system, meaning multiple actuators of the same coding type can operate the switch. This makes it more flexible and cost-effective for general machine applications compared to high-level coded F41 variants, while still maintaining robust safety functionality within NS-series architectures.
Key Advantages
- RFID safety interlock system for reliable machine guarding.
- Solenoid locking ensures guards remain secured during operation.
- F40 coding provides flexible actuator compatibility.
- Designed for integration into PL e / SIL 3 safety systems (system dependent).
- Robust industrial housing for harsh environments.
- Supports series connection in complex safety architectures.
Key Features
- Pizzato NS series safety locking switch.
- Model: NSE4ZZ1SMK-F40.
- RFID low-level coded actuator system (F40 coding).
- Solenoid locking mechanism (power-to-lock principle).
- Industrial-grade thermoplastic housing construction.
- IP67 / IP69K protection rating for harsh environments (series dependent).
