Why Choose the Pizzato NS D4AZ1SA25-F41 Safety Locking Switch?
The Pizzato NS D4AZ1SA25-F41 is an NS series RFID safety locking switch with actuator designed for reliable monitoring and locking of protective guards, doors and access points on industrial machinery. It combines contactless RFID actuator recognition, solenoid-controlled guard locking and electronic safety monitoring in a robust technopolymer housing.
This configuration uses Pizzato's D working method, meaning the actuator is locked when the solenoid is de-energised. In Mode 1, the OS safety outputs are active when the protective guard is locked. The NS architecture provides two IS safety inputs, two OS safety outputs and dedicated O3 and O4 signalling outputs for actuator-inserted and actuator-locked status.
The NS D4AZ1SA25-F41 is supplied complete with the VN NS-F41 high-level coded RFID actuator. The SA25 configuration provides a 12-pole cable connection with a 25 m cable, while a front screwdriver-operated auxiliary release provides controlled manual unlocking when required. The NS series locking mechanism provides a holding force of 2,100 N.
Key Advantages
- Combines RFID guard monitoring and mechanical guard locking in one safety device.
- Supplied with the VN NS-F41 high-level coded actuator.
- High coding level provides enhanced resistance to foreseeable actuator substitution and manipulation.
- 2,100 N holding force provides robust retention of protective guards.
- D working method keeps the actuator locked with the solenoid de-energised.
- Dual IS1–IS2 safety inputs and OS1–OS2 safety outputs support modern safety architectures.
- Dedicated O3 and O4 outputs provide separate actuator and locking status information.
- 25 m pre-wired cable supports installations requiring an extended connection run.
- Front screwdriver-operated auxiliary release provides a practical manual unlocking facility.
- IP67 / IP69K protection supports demanding industrial environments.

Reliable RFID Guard Locking with Extended Cable Connection
The Pizzato NS D4AZ1SA25-F41 combines coded RFID actuator detection with monitored mechanical guard locking, allowing the safety system to supervise both the position and locked condition of a protective guard. The VN NS-F41 high-level coded actuator provides enhanced protection against foreseeable bypass attempts, making the switch suitable for safety-critical machine access points.
The 25 m pre-wired connection cable is particularly useful where the safety switch must be installed at a significant distance from the control enclosure or associated safety equipment. Combined with dual-channel safety inputs and outputs, separate actuator and lock signalling, robust guard retention and a front auxiliary release, this configuration provides a versatile machine-guarding solution.
Typical Applications
- Machine guard and access-door interlocking.
- Robotic cells and automated production lines.
- Packaging and processing machinery.
- Assembly and manufacturing equipment.
- Material handling and conveyor systems.
- Machine tools and automated work cells.
- Large machinery requiring an extended pre-wired safety-switch connection.
