Why Choose the Pizzato NSE4ZZ1SA1-F41 Safety Locking Switch?
The Pizzato NSE4ZZ1SA1-F41 is a compact and highly reliable RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. As part of the Pizzato NS series safety locking switch family, it delivers secure guard monitoring, actuator detection, and controlled access for modern machinery environments.
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 controlled and safe access to machine doors and safety enclosures.
The NSE4ZZ1SA1-F41 is widely used in OEM machinery, robotics systems, packaging equipment, and automated production lines where functional safety, diagnostics, 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 version 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 machine guarding applications.
