Why Choose the Pizzato NSH4ZZ1DA1-F41 Safety Locking Switch?
The Pizzato NSH4ZZ1DA1-F41 is a high-reliability RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. As part of the advanced Pizzato NS series safety locking switch family, it provides secure guard locking, actuator monitoring, and high-integrity safety performance for modern machinery environments.
This model is engineered to ensure that protective guards remain locked during hazardous machine operation and only allow access when safe conditions are confirmed. Its integrated RFID-coded actuator system provides strong tamper resistance, while the solenoid locking mechanism ensures dependable control of safety doors and access points in automated production lines.
The NSH4ZZ1DA1-F41 is widely used in OEM machinery and industrial automation systems requiring high functional safety, robust diagnostics, and compliance with international machine safety standards such as ISO 14119. It is suitable for safety architectures up to PL e / SIL 3 depending on the overall system design.
This variant belongs to the NS Mode 2 operating family, featuring an energised solenoid locking principle combined with a high-level coded F41 RFID actuator, meaning each actuator is uniquely paired to the device for maximum anti-tamper protection. This ensures only a specifically taught actuator can operate the switch.
