Why Choose the Pizzato NSG4ST1SMK-F41 Safety Locking Switch?

The Pizzato NSG4ST1SMK-F41 is a high-integrity RFID-coded safety locking switch with actuator designed for machine guarding, interlocking, and industrial safety applications. It is part of the advanced Pizzato NS series safety switch platform, widely used in automation systems where secure access control and reliable guard locking are required.

This model uses a de-energised solenoid locking mechanism combined with a high-level F41 RFID-coded actuator, ensuring that only the correctly paired actuator can unlock the guard. This enhances protection against tampering and supports safe operation in robotic cells, packaging lines, and industrial machinery.

With a strong retention force of up to 2100 N and a rugged IP67/IP69K-rated technopolymer housing, the NSG4ST1SMK-F41 is built for demanding industrial environments requiring high reliability and safety performance. RatingValue: 4.8

Key Advantages

  • High-security F41 RFID high coding level for anti-tamper protection.
  • 2100 N locking/retention force for secure guard holding.
  • IP67 and IP69K protection rating for harsh environments.
  • Fail-safe de-energised solenoid locking principle.
  • Designed for high-integrity industrial safety circuits.

Key Features

  • Pizzato NS series safety locking switch.
  • Model: NSG4ST1SMK-F41.
  • High coding level RFID actuator (F41).
  • Key-operated guard release version.
  • Dual safety outputs (OS1 / OS2).
  • Status monitoring outputs for actuator insertion and lock state.
  • Auxiliary release function for emergency access.
  • M12 12-pin connector interface.

Advanced Safety Performance for Industrial Machinery

The NSG4ST1SMK-F41 ensures machinery remains safely isolated whenever a guard is open. Operation is only permitted when the correct RFID-coded actuator is detected and the guard is fully closed and locked, reducing the risk of accidental or unauthorized machine start-up.

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