Why Choose the Pizzato NSD4CE1SPK-F41 Safety Interlock Switch?
The Pizzato NSD4CE1SPK-F41 is a high-security RFID safety interlock switch with solenoid guard locking, designed for industrial machinery requiring strong tamper resistance, reliable actuator recognition, and dependable access control. Manufactured by Pizzato Elettrica, it belongs to the NS series safety locking switches widely used in OEM automation and machine guarding systems.
This model features a high-coded RFID actuator (F41 level) combined with a compact SPK housing configuration. Compared to low-coded variants, F41 provides one-to-one actuator recognition, significantly reducing the risk of unauthorized access or bypass.
The NSD4CE1SPK-F41 operates using a D working principle, where the actuator is locked by a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, the correct actuator is detected, and the system confirms a safe machine state. {index=1}
Key Advantages
- High-coded RFID actuator system (F41) for maximum security.
- Integrated solenoid guard locking for machine safety.
- Compact SPK design for easy mounting on machine guards.
- Reliable detection of door status and actuator insertion.
- Improved protection against tampering and bypass attempts.
- Suitable for high-risk industrial automation applications.
Key Features
- Pizzato NS series safety interlock switch.
- Model: NSD4CE1SPK-F41.
- High-coded RFID actuator system (F41).
- 2 safety outputs (OS1–OS2).
- 1 actuator inserted output (O3).
- 2 solenoid activation inputs (IE1–IE2).
- 1 reset/programming input (I3).
- M12, 12-pole industrial connector.
- Compact industrial-grade housing.
High-Integrity Machine Guarding
The NSD4CE1SPK-F41 ensures that machine guards remain locked until hazardous motion has fully stopped. The high-coded RFID system ensures that only the correct actuator can operate the switch, reducing risks of substitution or bypass.
Its safety outputs integrate directly with PLC safety controllers, enabling real-time monitoring of guard position, actuator presence, and lock status in automated production systems. {index=2}
