NS D4CE1STK-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NSD4CE1STK-F41 Safety Locking Switch?

The Pizzato NSD4CE1STK-F41 is an NS series RFID safety interlock switch with electromagnetic guard locking, supplied with a high-level coded F41 actuator. Designed for industrial machine guarding, it combines contactless RFID actuator recognition, electronic safety monitoring and robust guard retention for machinery where access must remain controlled until hazardous conditions have ceased.

This model uses the D working method, meaning the actuator is locked while the electromagnet is de-energised. It operates in Mode 1, with the OS safety outputs active when the guard is closed and locked. The supplied VN NS-F41 actuator provides a high coding level, with dedicated actuator recognition for applications requiring enhanced protection against inappropriate actuator substitution.

The NSD4CE1STK-F41 provides two safety inputs and two safety outputs, dedicated actuator and locking status outputs, two electromagnet activation inputs and a programming/reset input. The CE release configuration incorporates a front screwdriver-operated auxiliary release and rear escape-release pushbutton, while the STK connection configuration uses a bottom-mounted 19-pole M23 connector.

High-Coded RFID Monitoring with Escape Release

Guard-locking safety switches are particularly useful on machinery where hazardous conditions can persist after a stop command, such as equipment with rotating components, stored energy or run-down movement. The Pizzato NSD4CE1STK-F41 combines RFID guard detection with electromagnetic locking so the safety system can monitor the guard and maintain controlled access while hazardous conditions remain.

The supplied F41 actuator provides high-level coding, while the CE release arrangement combines a front auxiliary release with a rear escape-release pushbutton. Together with redundant electronic safety inputs and outputs and a strong locking mechanism, this makes the switch suitable for enclosed automated machinery and guarded areas where dependable interlocking and an internal escape facility are required.

Typical Applications

• Robotic cells and enclosed automated systems.
• Industrial machine guard doors and access points.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Machinery with hazardous residual or run-down movement.
• Guarded areas requiring a rear escape-release facility.
• Conveyor and material handling systems.
• OEM machinery requiring high-coded RFID guard locking.
