Why Choose the Pizzato ST DL420N5-E0T Safety Sensor?
The Pizzato ST DL420N5-E0T is a robust RFID-coded non-contact safety sensor designed for monitoring guards, doors and protective devices on industrial machinery. Part of the Pizzato ST D series, it combines RFID sensing technology with redundant safety electronics to provide reliable guard monitoring without the mechanical wear associated with conventional electromechanical safety switches.
The ST DL420N5-E0T features two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. This configuration supports integration into advanced machine safety architectures and allows compatible Pizzato safety devices to be connected in series while maintaining a high functional safety level when the system is correctly designed.
Operating from a 24 V DC supply, this version is supplied with a large E0T actuator featuring low-level coding and an actuation distance of 20 mm. The technopolymer sensor housing has its connection output on the left, while the PVC cable, wide operating temperature range and IP67 / IP69K protection make the assembly suitable for demanding industrial environments.

Reliable RFID Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST D series monitor the position of machine guards without requiring physical contact between the sensor and actuator. When the coded actuator enters the sensor's safe activation zone, the safety outputs can signal the machine safety control system that the protective guard is correctly positioned, helping prevent hazardous movement when access protection is open.
The ST DL420N5-E0T combines redundant electronics with safety inputs and outputs that support series connection with compatible Pizzato devices. Its large E0T actuator and 20 mm sensing distance are particularly useful where additional alignment tolerance is required, while the non-contact operating principle provides long service life in machinery subject to frequent guard opening cycles.
Typical Applications
- Machine guard and access-door monitoring.
- Automated production and assembly lines.
- Packaging and processing machinery.
- Robotic cells and perimeter guarding systems.
- Conveyor and material handling equipment.
- Industrial machinery with frequently operated protective guards.
