ST DL420M0.1-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL420M0.1-E1T ST D Series Safety Sensor?

The Pizzato ST DL420M0.1-E1T is a programmable RFID non-contact safety sensor designed for reliable monitoring of machine guards, access doors and protective devices in industrial automation systems. As part of the advanced Pizzato ST D safety sensor series, it uses digitally coded RFID technology to provide dependable guard detection without mechanical contact, helping reduce wear while providing enhanced protection against manipulation.

Operating from a 24 V DC supply, the ST DL420M0.1-E1T provides two IS1–IS2 safety inputs, two OS1–OS2 safety outputs, one O3 signalling output and one I3 programming input. The ST D series uses redundant electronic architecture and can be incorporated into suitably designed machine safety systems up to PL e, Category 4 according to EN ISO 13849-1 and SIL 3 according to IEC 61508 and IEC 62061.

The ST DL420M0.1-E1T uses an SM E1T high-coded RFID actuator with an actuation distance of 20 mm. The E1T actuator uses individual coding, providing a high coding level according to ISO 14119. This version is supplied with a 0.1 m PVC cable and M12 connector positioned on the left, while IP67 / IP69K protection and an operating temperature range of -25 °C to +70 °C support dependable operation in demanding industrial environments.

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 reduces 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 DL420M0.1-E1T combines a high-coded actuator with a 20 mm actuation distance and programmable electronic architecture. The individually coded E1T actuator improves protection against inappropriate substitution or deliberate bypassing, while the safety inputs and outputs enable connection with compatible Pizzato safety devices for flexible multi-guard machine safety architectures.

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.
