NS D4SE1SP0.2 Pizzato NS series safety locking switch

Why Choose the Pizzato NS D4SE1SP0.2 Safety Locking Switch?

The Pizzato NS D4SE1SP0.2 is a high-performance safety interlock switch with guard locking and RFID technology designed for monitoring and locking guards, doors and access points on industrial machinery. As part of the advanced Pizzato NS series, it combines contactless RFID actuator detection with electromagnetic guard locking to provide dependable protection for safety-related machine applications.

The NS series is designed to achieve high safety performance while simplifying machine guarding installations. Its reinforced technopolymer housing, digitally coded RFID operating principle and electronic safety outputs make it suitable for modern automated machinery where reliable guard monitoring and controlled access are required.

The NS D4SE1SP0.2 uses operating principle D, in which the actuator remains locked when the electromagnet is de-energised. It provides 2 redundant OS1-OS2 safety outputs, an actuator-inserted signalling output, electromagnet activation inputs and a programming/reset input, while offering a maximum actuator holding force of 2100 N.

Key Advantages

• Combines RFID safety monitoring and electromagnetic guard locking in one device.
• 2100 N maximum actuator holding force for secure machine guarding.
• Designed to support safety systems up to PL e and SIL 3.
• 2 redundant safety outputs OS1-OS2 for integration with safety control systems.
• Durable reinforced technopolymer housing for industrial applications.
• IP67 and IP69K protection supports installation in demanding operating environments.
• Front key release and rear escape release provide practical access and emergency release functionality.

Reliable RFID Guard Monitoring and Locking

Safety locking switches are used where a machine guard must remain securely closed until hazardous movement or another dangerous machine condition has ended. The Pizzato NS series combines electronic RFID guard detection with an electromagnetic locking mechanism, allowing the position and locking status of the guard to be incorporated into the machine safety control system.

The NS D4SE1SP0.2 is configured according to principle D so that the actuator is mechanically retained when the electromagnet is de-energised. Its redundant electronic safety outputs and high safety capability make the switch suitable for safety-related machinery, while the orientable modules and integrated release functions provide flexibility during installation and operation.

Typical Applications

• Industrial machine guard doors and access panels.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Conveyor and material handling machinery.
• Machine tools and enclosed production equipment.
• Safety systems requiring controlled access to hazardous areas.
