Why Choose the Pizzato NSE4ZZ1SA2-F40 Safety Interlock Switch?
The Pizzato NSE4ZZ1SA2-F40 is a robust RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. Manufactured by Pizzato Elettrica, it is part of the NS series safety interlock family used to protect operators and control access to hazardous machinery.
This device is typically installed on safety doors, hinged guards, sliding panels, and access points on automated equipment. It prevents machinery from operating while a guard is open, supporting compliance with EN ISO 14119 functional safety standards and modern industrial safety architectures used in manufacturing environments.
The NSE4ZZ1SA2-F40 uses a low-level coded F40 RFID actuator system, meaning it can operate with compatible F40 actuators without individual pairing. This makes it ideal for applications where flexibility, easier maintenance, and actuator interchangeability are required.
Key Advantages
- Reliable RFID safety interlock with solenoid locking.
- F40 low-level coded actuator system for flexible actuator compatibility.
- Designed for industrial machine safety and automation systems.
- Dual-channel safety outputs for PLC and safety relay integration.
- Continuous monitoring of guard position and lock status.
- Durable technopolymer housing for harsh industrial environments.
Key Features
- Pizzato NS series safety interlock switch with locking function.
- Solenoid locking mechanism with fail-safe de-energised release principle.
- RFID-coded actuator system (F40 low-level coding).
- 2 safety outputs (OS1–OS2).
- Actuator insertion and lock status signalling outputs.
- SA2 configuration designed for compact industrial installation and wiring flexibility.
- M12 connector interface (typical NS series architecture).
Advanced Machine Guard Safety Control
The NSE4ZZ1SA2-F40 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking system prevents access until safe conditions are met, while the RFID system detects the presence of a compatible F40 actuator.
This makes it suitable for general industrial automation environments where flexible actuator compatibility, reliability, and safe access control are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machines and tooling equipment.
- Packaging and processing machinery.
- Material handling systems and conveyors.
- General machine safety interlocking systems.
