Why Choose the Pizzato NSE4TE1SMK-F41 Safety Interlock Switch?
The Pizzato NSE4TE1SMK-F41 is a high-security RFID safety interlock switch with solenoid locking designed for advanced machine guarding applications in industrial automation systems. Manufactured by Pizzato Elettrica, it belongs to the NS series safety interlock family used to control access to hazardous machinery and protect operators.
This device is typically installed on safety doors, hinged guards, sliding panels, and access points on automated machines. It ensures that machinery cannot operate while a guard is open, supporting compliance with EN ISO 14119 functional safety standards and PL e / SIL 3 safety system architectures used in industrial environments.
The NSE4TE1SMK-F41 uses a high-level coded F41 RFID actuator system, meaning it only operates with a uniquely paired actuator. This significantly increases protection against tampering, bypass attempts, and unauthorized access in safety-critical systems.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator system for maximum anti-tamper protection.
- Designed for industrial machine safety and automation systems.
- Dual-channel safety outputs for PLC and safety relay integration.
- Real-time monitoring of guard position and lock status.
- Robust 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.
- High-level coded RFID actuator system (F41 type).
- 2 safety outputs (OS1–OS2).
- Actuator inserted and locked status signalling outputs.
- SMK configuration designed for standard industrial mounting and wiring layouts.
- 12-pin M12 connector interface (typical NS series architecture).
Advanced Machine Guard Safety Control
The NSE4TE1SMK-F41 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking system prevents access until safe operating conditions are met, while the RFID system validates the presence of the correctly paired F41-coded actuator.
This makes it suitable for high-risk industrial automation environments where strong tamper resistance, controlled access, and functional safety compliance are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machining and tooling equipment.
- Packaging and processing machinery.
- Material handling systems and conveyors.
- High-security machine access control systems.
