Why Choose the Pizzato STDL420N2-D0T RFID Safety Sensor?
The Pizzato STDL420N2-D0T is a high-performance RFID safety sensor designed for reliable monitoring of machine guards, safety doors and access points in industrial automation systems. It belongs to the robust Pizzato ST D series safety sensor family, offering secure non-contact detection with excellent resistance to tampering, vibration and mechanical wear.
This model uses RFID-coded actuator recognition to ensure that only a valid actuator can authorise machine operation, improving safety integrity and supporting compliance with modern machinery safety standards. Its fully electronic switching system eliminates mechanical wear, ensuring long service life in demanding industrial environments. The ST D series supports safety architectures up to PL e / SIL 3 (system dependent).
With a 24 V DC power supply, 2 safety inputs, 2 safety outputs and 1 signalling output, the STDL420N2-D0T integrates easily into machine safety systems. The PVC cable output (N2 version) provides flexible wiring installation, while the IP67 / IP69K protection rating ensures reliable operation in harsh industrial environments such as washdown areas, dusty production lines and high-vibration machinery. {index=1}
