NS H4TE1DMK Pizzato NS series safety locking switch

Why Choose the Pizzato NS H4TE1DMK Safety Locking Switch?

The Pizzato NS H4TE1DMK 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 electronic actuator detection, mechanical guard locking and redundant electronic safety outputs in a robust technopolymer housing.

This specific NS H4TE1DMK configuration is supplied without an actuator, allowing the appropriate compatible NS series RFID actuator to be selected separately for the application. The switch uses the H operating principle, with the actuator locked when the electromagnet is energised, together with Mode 2 operation in which the OS safety outputs are active when the protective guard is closed.

The TE release 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, redundant safety inputs and outputs, a lateral M12 12-pole connector and IP67 / IP69K protection make the NS H4TE1DMK a versatile solution for demanding industrial machine-safety installations.

Key Advantages

• Combines RFID guard monitoring and mechanical guard locking in one compact safety switch.
• H operating principle locks the actuator when the electromagnet is energised.
• Maximum 2100 N actuator holding force provides strong mechanical guard retention.
• 2 safety inputs and 2 redundant safety outputs support modern safety-control architectures.
• Separate O3 and O4 signalling outputs provide actuator-inserted and actuator-locked status information.
• Rear escape-release button provides an internal release facility for accessible guarded areas.
• M12 12-pole connector provides a convenient detachable electrical interface.
• IP67 / IP69K protection supports installation in demanding industrial environments.

Reliable Guard Monitoring with Rear Escape Release

The Pizzato NS H4TE1DMK is designed for machinery where a protective guard must be electronically monitored and mechanically retained as part of the machine safety strategy. Its RFID-based architecture detects a compatible coded 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 useful for guarded zones that personnel may physically enter, providing a means of releasing the locking mechanism from inside the protected area. Redundant IS1–IS2 inputs and OS1–OS2 outputs, separate actuator and lock status signals and the M12 connection provide comprehensive integration with compatible industrial safety-control systems.

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.
