Why Choose the Pizzato NSH3ZZ1SQK-F41 Safety Locking Switch?
The Pizzato NSH3ZZ1SQK-F41 is a robust RFID safety interlock switch with solenoid locking designed for high-security machine guarding in industrial automation systems. It is part of the advanced Pizzato NS series safety locking switch family, engineered to ensure reliable guard control, actuator identification, and operator protection in demanding environments.
This device ensures that machine guards remain locked during hazardous operation and only unlock when safe conditions are confirmed. Its F41 high-level coded RFID system provides a unique actuator pairing for maximum anti-tamper protection, while the integrated solenoid locking mechanism ensures controlled and safe access to protected machine areas.
The NSH3ZZ1SQK-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 “H working principle” configuration, which typically uses an energised solenoid locking system (power-to-lock or power-assisted lock depending on safety state) and provides dual-channel safety monitoring outputs. Based on NS series architecture, Mode 2 operation enables safety outputs to remain active depending on actuator insertion and locking status, supporting advanced safety logic in industrial systems. (Based on NS H4-series functional architecture)
