NS D4CE1SA5 Pizzato NS series safety locking switch

Why Choose the Pizzato NS D4CE1SA5 Safety Locking Switch?

The Pizzato NS D4CE1SA5 is an advanced RFID safety locking switch with guard locking designed for reliable monitoring of protective guards and controlled access to hazardous areas on industrial machinery. As part of the Pizzato NS Safety Interlock Switches series, it combines contactless RFID actuator detection with electromagnetic guard locking to provide dependable machine safety and access control.

The NS D4CE1SA5 is supplied without an actuator, allowing the appropriate compatible RFID actuator to be selected separately for the installation. Its electronic RFID technology provides coded actuator detection, while the D working method locks the actuator when the electromagnet is de-energised.

With a maximum actuator holding force of 2,100 N, a robust technopolymer housing and IP67 and IP69K protection, the Pizzato NS D4CE1SA5 is suitable for demanding industrial environments. The switch also provides dual-channel safety inputs and outputs together with dedicated actuator and locking status signalling.

Key Advantages

• Advanced RFID safety locking switch technology for contactless protective guard monitoring.
• 2,100 N maximum actuator holding force helps secure protective guards during machine operation.

Reliable Safety Control for Industrial Machinery

RFID safety locking switches such as the Pizzato NS D4CE1SA5 provide an important interface between protective machine guards and the safety control system. The RFID actuator is detected electronically, allowing the safety system to verify the associated protective guard without relying on conventional mechanical actuator contacts.

The D working method locks the actuator with the electromagnet de-energised, providing the specified guard locking arrangement. The switch incorporates redundant safety inputs and outputs together with dedicated signalling and electromagnet activation connections, allowing it to be integrated into suitable safety relays, safety controllers and machine safety systems.

The NS series is designed with redundant electronics and can support high safety performance when correctly integrated into an appropriate safety system. Pizzato also specifies a maximum actuator holding force of 2,100 N, while the IP67 and IP69K protection ratings help the switch withstand demanding industrial conditions.
