Why Choose the Pizzato NSD4AZ1DMK-F40 Safety Locking Switch?
The Pizzato NSD4AZ1DMK-F40 is a high-reliability RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. It is part of the robust Pizzato NS series safety locking switch family, engineered to provide secure guard monitoring, actuator recognition, 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 F40 coded RFID system uses a shared coding principle, allowing compatibility with multiple F40 actuators while maintaining effective anti-tamper protection for general industrial safety applications. The integrated solenoid locking mechanism ensures dependable control of safety doors and protective enclosures.
The NSD4AZ1DMK-F40 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 architecture. Based on Pizzato NS-series design principles, it supports reliable actuator detection, guard status feedback, and integration into complex safety circuits with multiple interlocked devices. According to manufacturer architecture, NS D4 switches also support series connection in multi-device safety chains while maintaining diagnostic integrity.
