Why Choose the Pizzato NSD5CE1SMK-F41 Safety Interlock Switch?
The Pizzato NSD5CE1SMK-F41 is a high-security RFID safety interlock switch with solenoid guard locking, designed for industrial machinery that requires robust access control, precise actuator recognition, and high-integrity machine safety. Manufactured by Pizzato Elettrica, it is part of the NS series safety locking switches widely used in OEM automation and industrial guarding systems.
This model features a high-coded RFID actuator (F41 level), meaning each actuator is uniquely coded and must be specifically matched to the switch. This greatly reduces tampering risk compared to low-coded systems and improves machine safety compliance in demanding environments.
The NSD5CE1SMK-F41 operates using a D working principle, where the actuator is held by a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, the correct actuator is detected, and safe machine conditions are confirmed. {index=1}
Key Advantages
- High-coded RFID actuator system (F41) for maximum tamper resistance.
- Integrated solenoid guard locking for operator safety.
- Reliable detection of door position and actuator engagement.
- Enhanced protection against bypass or actuator substitution.
- Suitable for high-risk industrial automation applications.
- Designed for integration into modern safety control systems.

High-Integrity Machine Protection
The NSD5CE1SMK-F41 ensures that hazardous machine functions cannot operate unless the guard is properly closed and the correct RFID-coded actuator is present. The F41 coding level provides one-to-one actuator matching, significantly improving safety integrity compared to shared-code systems.
Its safety outputs integrate with PLC-based safety controllers, allowing continuous monitoring of guard status, actuator position, and locking condition in automated production systems. {index=2}
