Why Choose the Pizzato NSM4TE1SMK Safety Locking Switch?
The Pizzato NSM4TE1SMK is a high-reliability RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. As part of the advanced Pizzato NS series safety locking switch family, it provides secure guard locking, actuator monitoring, and dependable protection for hazardous machinery environments.
This model is engineered to ensure that machine guards remain locked during hazardous operations and only release when safe conditions are met. Its integrated RFID-coded actuator system provides reliable identification, while the solenoid locking mechanism ensures controlled access to safety doors and protective enclosures.
The NSM4TE1SMK is widely used in OEM machinery and industrial automation systems requiring high functional safety, robust diagnostics, and seamless integration into safety-rated control architectures. It is designed in accordance with ISO 14119 principles and supports safety system architectures up to PL e / SIL 3 depending on installation.
This model belongs to the NS “Mode 3” operating family, which combines locked actuator monitoring with de-energised solenoid control and dual-channel safety outputs for enhanced system flexibility and diagnostics.
Key Advantages
- High-security RFID-coded machine safety interlock system.
- Solenoid locking ensures guards remain secured during hazardous motion.
- High resistance to tampering and actuator bypass attempts.
- Designed for integration into PL e / SIL 3 safety architectures (system dependent).
- Robust industrial construction for demanding environments.
- Supports series connection of multiple safety devices in safety chains.
Key Features
- Pizzato NS series safety locking switch.
- Model: NSM4TE1SMK.
- RFID high-level coded actuator system (F41 coding family).
- Solenoid locking mechanism for controlled guard access.
- Dual-channel safety monitoring outputs (system dependent).
- Technopolymer industrial housing.
- IP67 / IP69K protection rating for harsh industrial environments.
The Pizzato NSM4TE1SMK is designed to prevent access to hazardous machinery until all dangerous motion has fully stopped. Its RFID-coded system ensures only the correct actuator is recognised, reducing the risk of bypassing or tampering in industrial environments.
The NS series architecture allows multiple devices to be connected in safety chains while maintaining high safety integrity levels, making it suitable for complex automated production systems.
Typical Applications
- Industrial machine guarding systems.
- Automated production and assembly lines.
- Robotics safety enclosures.
- Packaging and processing machinery.
