NS H4ZZ1DA2-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS H4ZZ1DA2-F41 Safety Locking Switch?

The Pizzato NS H4ZZ1DA2-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 Safety Switch Series, it combines coded electronic actuator detection, mechanical guard locking and redundant safety functions in a compact industrial technopolymer housing.

Supplied with the VN NS-F41 high-level coded RFID actuator, the NS H4ZZ1DA2-F41 provides reliable non-contact identification of the associated guard actuator. High-level RFID coding helps reduce the possibility of foreseeable manipulation and makes this configuration particularly suitable for machinery where secure actuator identification forms an important part of the safety strategy.

The switch uses the H working principle, with the actuator locked when the electromagnet is energised. The ZZ configuration is designed without auxiliary or escape release, while the locking mechanism provides a maximum actuator holding force of 2100 N. This DA2 version uses a factory-fitted 2 m cable for integration into the machine safety and control system.

Key Advantages

• Combines RFID guard monitoring and mechanical guard locking in one compact device.
• VN NS-F41 high-level coded RFID actuator provides enhanced protection against foreseeable actuator substitution.

Reliable High-Coded RFID Guard Locking

The Pizzato NS H4ZZ1DA2-F41 is designed for machinery where a protective guard must be electronically monitored and mechanically retained according to the machine safety strategy. RFID technology identifies the high-level coded F41 actuator without mechanical contact, while the integrated electromagnetic locking mechanism keeps the actuator retained when the electromagnet is energised.

Its redundant electronic safety architecture allows integration with compatible safety controllers, while dedicated status signals enable the machine control system to monitor guard and locking conditions. The ZZ configuration eliminates manual auxiliary and escape releases, making it suitable for installations where these release functions are not required by the machine design.

Typical Applications

• Machine guard and safety-door interlocking.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Conveyor and material handling systems.
• Machine tools and industrial production equipment.
• Guarded hazardous areas requiring controlled access.
• OEM machinery and factory automation installations.
