Why Choose the Pizzato ST DL420N5-D0T ST D Series Safety Sensor?
The Pizzato ST DL420N5-D0T 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 RFID safety sensor series, it uses electronically coded RFID technology to detect the associated actuator without mechanical switching contact, helping minimise wear and provide dependable safety monitoring on frequently operated machinery.
Operating from a 24 V DC supply, the ST DL420N5-D0T provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, one O3 signalling output and one I3 programming input. The programmable 420 configuration supports flexible integration into machine safety architectures, while the ST D platform can be incorporated into suitably designed safety systems up to PL e, Category 4 and SIL 3.
The ST DL420N5-D0T uses a D0T low-coded RFID actuator with an actuation distance of approximately 12 mm. The N5 configuration incorporates an integrated 5 m cable with left-side exit, making it particularly useful where a longer direct cable run is required between the safety sensor and control system. Its robust technopolymer construction, IP67 / IP69K protection and wide industrial operating temperature range support dependable use in demanding machinery applications.

Reliable Programmable 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 switching contact between the sensor and actuator. This contactless operating principle helps minimise mechanical wear and supports dependable monitoring where guards are frequently opened during production, maintenance, cleaning or machine changeover procedures.
The ST DL420N5-D0T combines a D0T RFID actuator with programmable electronic safety architecture and a practical 5 m integrated cable. Its two safety inputs support integration with compatible safety devices, while the signalling and programming functions provide additional flexibility for industrial machine safety systems requiring reliable non-contact guard monitoring and longer direct cable runs.
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 programmable non-contact RFID safety interlocking.
