Why Choose the Pizzato NSE3ZZ1SQK-F40 Safety Interlock Switch?
The Pizzato NSE3ZZ1SQK-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 belongs to 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. It ensures machinery cannot operate while a guard is open, helping maintain compliance with EN ISO 14119 machine safety standards and modern functional safety requirements in industrial environments.
The NSE3ZZ1SQK-F40 uses a low-level coded F40 RFID actuator system, meaning it accepts any compatible F40 actuator. This makes it suitable for flexible installation and maintenance while maintaining reliable safety performance across general-purpose industrial applications.
Key Advantages
- Reliable RFID safety interlock with solenoid locking.
- F40 low-level coded actuator system for interchangeable use.
- 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 industrial housing suitable for harsh 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.
- SQK configuration designed for standard mounting and wiring layout flexibility.
- Industrial sealed housing for demanding environments.
Advanced Machine Guard Safety Control
The NSE3ZZ1SQK-F40 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking mechanism prevents access until safe operating conditions are achieved, while the RFID system detects the presence of a compatible F40-coded actuator.
This makes it suitable for general industrial environments where reliable safety, durability, and flexible actuator interchangeability are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machines and machining equipment.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- Safety doors and access-controlled machine areas.
