Why Choose the Pizzato ST DL420M0.1-L1T ST D Series Safety Sensor?
The Pizzato ST DL420M0.1-L1T is a programmable RFID non-contact safety sensor with actuator designed for monitoring guards, doors and protective devices on industrial machinery. Part of the Pizzato ST D RFID Safety Sensor series, it combines electronic RFID actuator recognition with solid-state safety switching, providing dependable guard monitoring without the mechanical wear associated with conventional contact-based safety switches.
The ST DL420M0.1-L1T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. The 420 configuration is programmable, providing additional flexibility for integration into modern machine safety architectures and allowing compatible safety devices to be incorporated into series-connected systems.
Operating from a 24 V DC supply, this version features a 0.1 m cable with an M12 connector positioned on the left-hand side of the sensor. The supplied SM L1T actuator has a high coding level according to ISO 14119, a 12 mm actuation distance and compact 53 × 16 × 7 mm dimensions. The technopolymer construction, IP67 / IP69K protection and operating temperature range of -25 °C to +70 °C make the sensor suitable for demanding industrial safety applications.
Key Advantages
- Non-contact RFID safety sensing technology reduces mechanical wear and maintenance requirements.
- SM L1T high-coded actuator provides enhanced protection against actuator substitution and manipulation.

Reliable High-Coded RFID Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST D series monitor movable guards without requiring mechanical contact between the sensor and actuator. The high-coded SM L1T actuator is individually coded, allowing the associated sensor to recognise its specific actuator and providing greater protection against deliberate or accidental substitution than a low-coded actuator arrangement.
The ST DL420M0.1-L1T combines high-coded actuator recognition with safety inputs, safety outputs, signalling and programmable functionality, making it a flexible solution for sophisticated automated machinery. Its compact L-type actuator, short cable with M12 connector and sealed IP67 / IP69K construction simplify installation while supporting reliable operation in high-cycle and demanding industrial environments.
Typical Applications
- Machine guard and safety-door monitoring.
- Industrial production and assembly machinery.
- Packaging and processing equipment.
- Automated manufacturing cells and robotic systems.
- Conveyors and material handling equipment.
- Machinery requiring high-coded RFID protection against actuator substitution.
