Why Choose the Pizzato NSH3ZZ1SMK-F41 Safety Locking Switch?

The Pizzato NSH3ZZ1SMK-F41 is a high-integrity RFID-coded safety locking switch with actuator designed for machine guarding, interlocking, and industrial safety applications. It belongs to the proven Pizzato NS series safety switch family, widely used in OEM machinery and automation systems requiring reliable guard locking and high-level access control.

This model uses an electromagnetic guard locking mechanism combined with a high coding level F41 RFID actuator, ensuring that only a uniquely paired actuator can authorise access. This significantly reduces tampering risk and supports safe operation in robotics, packaging machinery, and automated production environments.

With a strong retention force of up to 2100 N and IP67/IP69K protection, the NSH3ZZ1SMK-F41 is designed for harsh industrial conditions, including washdown areas and high-duty automation systems. RatingValue: 4.7

Key Advantages

  • High-security F41 RFID high coding level for strong anti-tamper protection.
  • 2100 N locking/retention force for secure guard holding.
  • IP67 and IP69K protection rating for harsh industrial environments.
  • Reliable solenoid-based guard locking system.
  • Designed for OEM machine safety and interlocking systems.

Key Features

  • Pizzato NS series safety locking switch.
  • Model: NSH3ZZ1SMK-F41.
  • High coding level RFID actuator (F41).
  • Electromagnetic guard locking mechanism.
  • Dual safety outputs (OS1 / OS2).
  • Actuator presence and lock status monitoring outputs.
  • M12 connector interface (system dependent configuration).
  • Rugged industrial-grade technopolymer housing.

Advanced Safety Performance for Industrial Machinery

The NSH3ZZ1SMK-F41 ensures machinery remains safely isolated whenever a guard is open. Operation is only permitted when the correct F41-coded actuator is detected and the guard is fully closed and locked, reducing the risk of accidental machine start-up.

Its high coding RFID system provides strong resistance against duplication and bypass attempts, making it suitable for robotics, packaging systems, and high-risk industrial environments.

Typical Applications

  • Industrial machine guarding systems
  • Robotic automation cells
  • Automated production lines
  • Packaging machinery safety doors
  • OEM equipment integration
  • High-integrity safety interlocking systems
