NS H3TE1SQK-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS H3TE1SQK-F41 Safety Locking Switch?

The Pizzato NS H3TE1SQK-F41 is an advanced RFID safety interlock switch with guard locking designed for reliable monitoring and controlled access to hazardous areas of industrial machinery. Part of the Pizzato NS series, it combines high-level coded RFID actuator detection, mechanical guard locking and redundant electronic safety outputs in a robust technopolymer housing.

Supplied with the VN NS-F41 high-level coded RFID actuator, the NS H3TE1SQK-F41 provides enhanced protection against foreseeable manipulation and actuator substitution. The switch uses H operating principle, Mode 2, with the actuator locked when the electromagnet is energised and the OS safety outputs active when the protective guard is closed.

The TE configuration has no front auxiliary release and incorporates a rear escape-release button, making it particularly suitable for guarded areas that personnel may enter. A maximum actuator holding force of 2100 N, M12 8-pole connector for series connection and IP67 / IP69K protection provide a capable solution for demanding industrial machine-safety installations.

Key Advantages

• Combines RFID guard monitoring and mechanical guard locking in one compact safety device.
• VN NS-F41 high-level coded RFID actuator helps reduce foreseeable manipulation and actuator substitution.

Reliable High-Coded RFID Guard Locking with Escape Release

The Pizzato NS H3TE1SQK-F41 is designed for machinery where a protective guard must be electronically monitored and mechanically retained as part of the machine safety strategy. Its high-level coded RFID system identifies the associated F41 actuator without mechanical contact, while the integrated locking mechanism retains the actuator whenever the electromagnet is energised.

The rear escape-release button makes this configuration particularly valuable for guarded areas that personnel may enter, providing a means of releasing the locking mechanism from inside the protected zone. Redundant OS1–OS2 safety outputs, dedicated O4 locking-status signalling and the M12 connection provide straightforward integration with compatible industrial safety controllers and series-connected safety architectures.

Typical Applications

• Machine guard and safety-door interlocking.
• Robotic cells and enclosed automation systems.
• Guarded areas requiring an internal escape-release function.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Conveyor and material handling systems.
• Machine tools and industrial production equipment.
• OEM machinery and factory automation installations.
