Why Choose the Pizzato ST DL420M0.5-L1T ST D Series Safety Sensor?
The Pizzato ST DL420M0.5-L1T is a programmable RFID non-contact safety sensor designed for reliable monitoring of machine guards, access doors and protective devices in industrial automation systems. Part of the Pizzato ST D safety sensor series, it uses electronically coded RFID technology to detect the associated actuator without mechanical contact, helping reduce wear while providing dependable safety monitoring on frequently operated machinery.
Operating from a 24 V DC supply, the ST DL420M0.5-L1T provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, one O3 signalling output and one I3 programming input. Its redundant electronic architecture enables integration into suitably designed machine safety systems up to PL e, Category 4 and SIL 3, making it suitable for demanding industrial safety applications.
The ST DL420M0.5-L1T uses an L1T high-coded RFID actuator with an actuation distance of 12 mm. The high-coded actuator provides enhanced protection against substitution and manipulation in accordance with the coding principles of ISO 14119. This version features a 0.5 m cable with M12 connector positioned on the left, combining convenient machine wiring with the robust construction of the ST D platform.

Reliable High-Coded RFID Guard Monitoring for Industrial Machinery
RFID safety sensors such as the Pizzato ST D series monitor movable guards and protective devices without requiring mechanical contact between the sensor and actuator. This contactless operating principle helps reduce mechanical wear compared with conventional interlock switches and provides reliable operation on machinery where guards are frequently opened during production, maintenance and changeover procedures.
The ST DL420M0.5-L1T combines a high-coded L1T actuator with programmable electronic safety architecture. Its two safety inputs allow compatible safety devices to be connected in series, while the dedicated programming input expands configuration possibilities for machine builders requiring flexible guard monitoring across complex automated machinery.
Typical Applications
- Industrial machine guard and access-door monitoring.
- Packaging and production machinery.
- Automated assembly equipment.
- Robotic cells and industrial automation systems.
- Material handling and conveyor machinery.
- OEM machinery requiring high-coded non-contact safety interlocking.
