Why Choose the Pizzato STDL420MK-L1T RFID Safety Sensor?
The Pizzato STDL420MK-L1T is a high-reliability RFID safety sensor designed for monitoring machine guards, safety doors and access points in industrial automation systems. As part of the advanced Pizzato ST D series safety sensor family, it delivers secure non-contact detection with excellent resistance to tampering, vibration and mechanical wear.
The device uses RFID-coded actuator recognition to ensure that only the correct actuator enables machine operation, improving safety integrity and helping meet modern machine safety requirements. Its fully electronic switching design eliminates mechanical wear, making it suitable for long-life use in demanding industrial environments. According to ST D-series specifications, it supports safety applications up to PL e / SIL 3.
With a 24 V DC supply, 2 safety inputs, 2 safety outputs and 1 signalling output, the STDL420MK-L1T integrates easily into machine safety architectures. The M12 connector (MK version) and IP67 / IP69K protection rating ensure reliable performance even in harsh industrial and washdown environments.
