Pizzato NSD4CE1SMK RFID safety interlock switch with solenoid guard locking for industrial machine safety and access control applications.
£248.90
Why Choose the Pizzato NSD4CE1SMK Safety Interlock Switch?
The Pizzato NSD4CE1SMK is a high-performance RFID safety interlock switch with solenoid guard locking, designed for industrial machinery that requires secure access control, reliable actuator detection, and high-integrity safety monitoring. Manufactured by Pizzato Elettrica, it is part of the advanced NS series safety locking devices used widely in OEM automation systems and machine guarding applications.
This model belongs to the NS series “SMK” configuration, which combines a compact safety interlock body with RFID-coded actuator recognition and robust mechanical locking. It is engineered to prevent access to hazardous machine areas until all dangerous motion has stopped and safety conditions are confirmed.
The NSD4CE1SMK operates with a solenoid-controlled locking mechanism and RFID actuator verification. Safety outputs are enabled only when the guard is closed, the actuator is correctly detected, and the system confirms a safe machine state. {index=1}
Key Advantages
- High-security RFID actuator recognition system.
- Integrated solenoid guard locking for machine protection.
- Compact design for easy installation on machine guards and doors.
- High holding force for strong door retention in industrial environments.
- Supports advanced safety architectures (up to PL e / SIL 3 system dependent).
- Suitable for harsh industrial conditions with high IP protection ratings.
Key Features
- Pizzato NS series safety interlock switch.
- Model: NSD4CE1SMK.
- RFID-coded actuator system (high coding level option available in NS series).
- 2 safety outputs for integration into safety controllers.
- Solenoid-driven guard locking mechanism.
- Actuator presence and lock status monitoring outputs.
- 12-pin M12 electrical connection.
- Compact industrial-grade housing.
Reliable Machine Guarding for Industrial Automation
The NSD4CE1SMK is designed to ensure that machine guards remain locked until hazardous movement has completely stopped. The RFID system provides reliable actuator identification, significantly reducing the risk of tampering or bypassing safety interlocks.
Its safety outputs integrate directly with PLC safety systems, enabling real-time monitoring of door status, actuator engagement, and lock condition within automated production environments. {index=2}
