Why Choose the Pizzato NS D4AZ1SRK-N187 Safety Locking Switch?
The Pizzato NS D4AZ1SRK-N187 is a high-performance RFID safety locking switch designed for monitoring and locking machine guards in industrial automation and safety applications. As part of the advanced Pizzato NS series safety interlock switches, it combines contactless RFID actuator detection with guard locking technology to provide reliable protection for hazardous machinery areas.
The NS series is developed for applications where dangerous machine movements may continue after shutdown, requiring controlled access to protected areas. Its RFID technology provides high coding levels for improved tamper resistance, while the integrated locking mechanism helps prevent opening of the guard until safe conditions are achieved.
The NS D4AZ1SRK-N187 features a de-energised solenoid locking principle and is designed for integration into modern safety circuits. The switch provides dual-channel safety monitoring, signalling outputs for actuator and locking status, and compatibility with industrial safety control systems.
