Why Choose the Pizzato NSE4ZZ1SMK-E37 Safety Locking Switch?
The Pizzato NSE4ZZ1SMK-E37 is a high-reliability RFID safety interlock switch with solenoid locking designed for advanced machine guarding applications in industrial automation systems. It belongs to the robust Pizzato NS series safety locking switch family, engineered to provide secure guard monitoring, actuator detection, and controlled access in demanding industrial environments.
This device ensures that protective guards remain locked during hazardous machine operation and only unlock when safe conditions are confirmed. Its RFID-based actuator recognition system provides strong anti-tamper protection, while the integrated solenoid locking mechanism ensures safe and controlled access to machine doors and safety enclosures.
The NSE4ZZ1SMK-E37 is widely used in OEM machinery, robotics systems, packaging equipment, and automated production lines where functional safety and compliance with ISO 14119 machine safety standards are required. It can be integrated into safety systems up to PL e / SIL 3 depending on the overall system architecture.
This model belongs to the NS “E37” configuration family, where the E37 code defines a higher actuator extraction force (approx. 40 N), providing stronger retention of the actuator compared to standard versions. This improves safety against unintended opening or vibration-related release in industrial environments. It uses a power-to-lock architecture with RFID-coded actuator recognition for high-security machine guarding applications.
Key Advantages
- High-security RFID-coded safety interlock system for machine guarding.
- Solenoid locking ensures guards remain secured during hazardous operation.
- E37 actuator retention provides increased extraction force for safer locking.
- Designed for integration into PL e / SIL 3 safety systems (system dependent).
- Robust industrial thermoplastic housing for harsh environments.
- Reliable actuator detection with anti-tamper protection.
Key Features
- Pizzato NS series safety locking switch.
- Model: NSE4ZZ1SMK-E37.
- RFID safety actuator recognition system.
- Solenoid locking mechanism (power-to-lock principle).
- E37 high retention actuator extraction force variant.
- M12 12-pin electrical connection interface.
