Why Choose the Pizzato ST DD420N5-D1T ST D Series Safety Sensor?
The Pizzato ST DD420N5-D1T is a non-contact RFID safety sensor with high-coded actuator designed for monitoring guards, access doors and other protective devices on industrial machinery. Part of the Pizzato ST D series, it uses RFID coded non-contact switching to provide dependable guard position detection without the mechanical contact and associated wear of conventional electromechanical safety switches.
The ST DD420N5-D1T is supplied with a D1T high-coded RFID actuator offering an actuation distance of 12 mm. The actuator measures 45 × 25 × 18 mm and supports front and side fixing, providing installation flexibility for different machine guard arrangements. High-level coding, with individually coded actuators, provides enhanced protection against manipulation in safety-related applications.
Operating from a 24 V DC supply, the sensor provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. This configuration uses a 5 m PVC cable with the connection exiting from the right-hand side of the technopolymer housing. An operating temperature range from -25 °C to +70 °C and IP67 / IP69K protection make it suitable for demanding industrial machinery and automation environments.

Reliable RFID Safety Monitoring for Industrial Machinery
RFID safety sensors such as the Pizzato ST D series monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. The individually coded D1T RFID actuator is recognised electronically, allowing the machine safety system to determine whether the associated protective guard is correctly positioned before hazardous machine functions are permitted.
The 12 mm actuation distance provides useful installation tolerance, while high-level actuator coding improves protection against inappropriate substitution or manipulation. Combined with comprehensive safety I/O, a 5 m PVC cable and robust environmental protection, the ST DD420N5-D1T provides a dependable guard monitoring solution for modern industrial automation systems.
Typical Applications
- Industrial machine guard and access door monitoring.
- Packaging and production machinery.
- Robotic cells and automated manufacturing systems.
- Material handling and conveyor systems.
- Machine tools and processing equipment.
- Safety enclosures and protective guarding.
