Why Choose the Pizzato NSD4AZ1DPK-F41 Safety Locking Switch?
The Pizzato NSD4AZ1DPK-F41 is a robust RFID safety interlock switch with solenoid locking designed for machine guarding applications 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 high-risk 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 against substitution or bypass attempts. The integrated solenoid locking mechanism ensures precise and reliable control of access to protected machine areas.
The NSD4AZ1DPK-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, typically featuring a de-energised solenoid locking principle (power-to-unlock or power-to-release depending on configuration) combined with dual-channel safety monitoring. Based on Pizzato NS architecture, it supports reliable actuator detection, guard status feedback, and integration into complex safety circuits with multiple interlocked devices. NS devices in this family also support series connection of multiple units in safety chains while maintaining high diagnostic coverage and safety integrity.
