Why Choose the Pizzato NS H4ZZ1DMK Safety Locking Switch?
The Pizzato NS H4ZZ1DMK is an industrial RFID safety locking switch designed for monitoring and locking movable guards, safety doors and protected access points on machinery. As part of the Pizzato NS series, it combines coded non-contact guard detection with an integrated solenoid locking system for safety-related industrial applications.
This configuration uses the H working method, with the actuator locked when the solenoid is energised, together with Mode 2 operation, where the OS safety outputs are active when the protective guard is closed. It provides two IS safety inputs, two OS safety outputs and dedicated signalling outputs for actuator-inserted and actuator-locked status.
Operating from a 24 V DC supply, the NS H4ZZ1DMK provides a 2100 N locking force and uses a lateral M12 12-pin connector. This specific NS H4ZZ1DMK configuration is supplied without an actuator, allowing the appropriate compatible coded actuator to be selected separately for the machine-guarding installation.
Key Advantages
- Combines RFID guard monitoring and solenoid guard locking in one compact safety device.
- 2100 N locking force provides secure retention of the protective guard.

Reliable RFID Guard Monitoring and Solenoid Locking
RFID safety locking switches use coded non-contact detection to monitor the position of movable machine guards while an integrated locking mechanism controls access to protected areas. This combination enables machine safety systems to monitor guard position and locking status while communicating safety-related information to compatible control equipment.
The Pizzato NS H4ZZ1DMK uses an energised-solenoid locking principle and provides dedicated electronic safety and signalling channels. Its 2100 N locking force, industrial M12 connection and high environmental protection make it well suited to automated machinery requiring robust guard monitoring and controlled access.
Typical Applications
- Industrial machine guards and safety doors.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Assembly and production equipment.
- Material handling and conveyor systems.
- OEM machinery requiring RFID guard monitoring and solenoid locking.
