Why Choose the Pizzato NSD4AZ1DMK-F41 Safety Locking Switch?
The Pizzato NSD4AZ1DMK-F41 is a high-performance RFID safety interlock switch with solenoid locking designed for machine guarding in industrial automation systems. It belongs to the advanced Pizzato NS series safety locking switch family, engineered to provide secure guard monitoring, actuator identification, and controlled access in demanding industrial environments.
This device ensures that machine guards remain locked during hazardous operation and only release when safe conditions are confirmed. Its F41 high-level coded RFID system uses a uniquely paired actuator, delivering maximum anti-tamper protection and strong resistance to bypass or substitution attempts. The integrated solenoid locking mechanism ensures controlled access to protected machine areas.
The NSD4AZ1DMK-F41 is widely used in OEM machinery, robotics systems, packaging equipment, and automated production lines where functional safety and compliance with ISO 14119 machine safety standards are required. It can be integrated into safety systems up to PL e / SIL 3 depending on system architecture.
This model belongs to the NS “D4 configuration” family, which typically features an energised solenoid locking system (power-to-lock principle) combined with dual-channel safety monitoring. Based on manufacturer NS-series architecture, it supports reliable actuator detection, guard status feedback, and integration into complex safety circuits with multiple interlocked devices. The NS series also allows series connection of multiple switches (up to 32 devices) while maintaining high safety integrity levels in properly designed systems.
