Why Choose the Pizzato NS E4ZZ1DMK Safety Locking Switch?
The Pizzato NS E4ZZ1DMK is an industrial RFID safety locking switch with electromagnetic guard locking designed for monitoring and controlling access to hazardous areas of machinery. As part of the advanced Pizzato NS series, it combines electronic safety monitoring, guard locking and diagnostic signalling in a robust technopolymer housing.
The NS E4ZZ1DMK uses Pizzato's RFID-based safety technology and provides two safety inputs and two redundant safety outputs for integration into machine safety circuits. Its electronic architecture allows NS series devices to be connected in series where multiple guards require monitoring, helping simplify wiring in complex machinery and automated production systems.
This version operates according to Principle E, with the actuator locked when the electromagnet is energised, and uses Mode 1 operation in which the OS safety outputs are active when the guard is locked. It provides a maximum actuator holding force of 2100 N, an M12 12-pole connection and environmental protection to IP67 / IP69K. The NS E4ZZ1DMK is supplied without an actuator, allowing the appropriate compatible actuator to be selected separately.

Reliable Guard Locking for Industrial Machinery
Safety locking switches are used on machinery where access to a hazardous area must remain controlled until safe operating conditions have been established. The Pizzato NS series combines RFID guard detection with electromagnetic locking, allowing a machine safety system to monitor both the position and locking status of a movable guard.
The NS E4ZZ1DMK provides dedicated safety, signalling and electromagnet-control connections for integration with safety controllers and machine automation systems. Its rugged enclosure, high holding force and IP67 / IP69K environmental protection make it suitable for industrial equipment exposed to dust, moisture and demanding operating conditions.
Typical Applications
- Machine safety doors and movable guards.
- Automated manufacturing and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated production lines.
- Conveyor and material handling systems.
- Machining centres and production equipment with hazardous run-down periods.
- Industrial machinery requiring controlled guard access.
