Why Choose the Pizzato NSG4ST1SPK-F41 Safety Locking Switch?

The Pizzato NSG4ST1SPK-F41 is a high-performance RFID-coded safety locking switch with actuator designed for machine guarding, interlocking, and industrial safety applications. It belongs to the advanced Pizzato NS series safety switch family, widely used in OEM machinery and automated production environments where reliable guard locking and high-integrity access control are required.

This model combines an electromagnetic guard locking system with a high-level F41 RFID-coded actuator, ensuring that only the correctly paired actuator can authorise access. This significantly reduces tampering risks and supports safe operation in robotics, packaging machines, and industrial automation systems.

With a strong retention force of up to 2100 N, IP67/IP69K protection, and a rugged technopolymer housing, the NSG4ST1SPK-F41 is engineered for demanding industrial environments requiring both safety and durability. RatingValue: 4.8

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.
  • Fail-safe de-energised solenoid locking principle.
  • Designed for high-integrity safety circuits in automation systems.

Key Features

  • Pizzato NS series safety locking switch.
  • Model: NSG4ST1SPK-F41.
  • High coding level RFID actuator (F41).
  • Electromagnetic guard locking mechanism.
  • Dual safety outputs (OS1 / OS2).
  • Actuator insertion and lock status signalling outputs.
  • Auxiliary release function for emergency access.
  • M12 connector interface (system dependent configuration).

Advanced Safety Performance for Industrial Machinery

The NSG4ST1SPK-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, improving operator safety and reducing the risk of accidental 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
