Why Choose the Pizzato NSE4ZZ1SPK-F41 Safety Interlock Switch?
The Pizzato NSE4ZZ1SPK-F41 is a compact and reliable RFID safety interlock switch with solenoid locking designed for machine guarding and access control in industrial automation systems. Manufactured by Pizzato Elettrica, it belongs to the NS series of safety switches used to protect operators and ensure safe machine operation.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents machinery from operating while a guard is open, supporting compliance with EN ISO 14119 and modern functional safety standards used in industrial environments.
The NSE4ZZ1SPK-F41 uses a high-level coded F41 RFID actuator system, meaning it only operates with a uniquely paired actuator. This provides strong protection against tampering, bypass attempts, and unauthorized access in safety-critical applications.
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.
- Continuous monitoring of guard position and lock status.
- Compact industrial housing for flexible installation.
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 insertion and lock status monitoring outputs.
- SPK configuration designed for compact mounting and simplified wiring layouts in NS series systems.
- M12 connector interface (8-pin typical configuration)
Advanced Machine Guard Safety Control
The NSE4ZZ1SPK-F41 ensures machinery remains safely stopped whenever guards are open or not properly secured. The solenoid locking system prevents access until safe operating conditions are achieved, while the RFID system verifies the presence of the correct F41-coded actuator.
This makes it suitable for industrial automation environments where high reliability, tamper resistance, and compliance with modern safety standards are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machinery and tooling equipment.
- Packaging and processing machinery.
- Material handling systems and conveyors.
- Machine access safety interlocking systems.
