Why Choose the Pizzato NS D3SE1SQK-F41 Safety Locking Switch?
The Pizzato NS D3SE1SQK-F41 is a robust RFID safety locking switch with separate actuator, designed for reliable monitoring and locking of machine guards, access doors and hazardous areas in industrial automation systems. As part of the advanced Pizzato NS safety locking switch series, it combines non-contact RFID actuator detection, electronic safety monitoring and electromagnetic guard locking in a durable technopolymer housing.
The DSE working principle keeps the actuator locked when the electromagnetic solenoid is de-energised, helping maintain guard locking following loss of electrical power. The supplied VN NS-F41 high-coded RFID actuator provides a high coding level according to EN ISO 14119, helping prevent manipulation through actuator substitution. The switch also features a front key-operated auxiliary release and a rear anti-panic emergency release button for controlled manual release when required.
The NS D3SE1SQK-F41 uses Mode 1, with the safety outputs active when the actuator is inserted and the protective guard is locked. It provides two safety inputs, two safety outputs, actuator status signalling and solenoid control inputs. The M12 8-pole connector provides a compact connection for integration into suitable machine safety systems.

Reliable Machine Guarding and Safety Control
The Pizzato NS series combines RFID actuator recognition with electronic safety monitoring and electromagnetic guard locking to provide a dependable interface between machine guards and safety control systems. The non-contact RFID technology detects the high-coded F41 actuator while the electronic safety outputs communicate the guard status to a suitable safety PLC or safety module.
The NS D3SE1SQK-F41 uses the DSE working principle, meaning the actuator remains locked when the electromagnetic solenoid is de-energised. Its Mode 1 configuration activates the OS1 and OS2 safety outputs when the actuator is correctly inserted and locked, while O3 and O4 provide separate actuator-inserted and actuator-locked status signals. The front key release and rear anti-panic emergency release provide controlled manual access when required.
Typical Applications
- Machine guarding and safety access doors.
- Industrial production and processing machinery.
- Automated manufacturing systems.
- Packaging and material handling equipment.
- Robotic cells and automated workstations.
- Machines with hazardous movement or stored energy.
- Safety circuits requiring RFID-coded guard locking.
- Industrial machinery requiring emergency release from protected areas.
