Why Choose the Pizzato ST DD211N2-D1T ST D Series Safety Sensor?
The Pizzato ST DD211N2-D1T is a compact and highly reliable RFID non-contact safety sensor designed for monitoring machine guards, access doors and protective devices in industrial automation systems. As part of the advanced Pizzato ST D series, it uses RFID technology and a uniquely coded actuator to provide dependable guard-position detection with a high level of protection against tampering and bypassing.
Its fully electronic, non-contact operating principle eliminates mechanical switching elements, reducing wear and providing a long service life even in machinery with frequent operating cycles. The ST D series can support safety systems up to PL e, Category 4 and SIL 3 when correctly integrated with suitable safety control equipment, making it well suited to demanding machine-safety applications.
The ST DD211N2-D1T operates from a 12–24 V DC supply and provides two safety outputs plus one signalling output. This N2 version features an integrated 2 m PVC cable, while the DD housing configuration provides the cable output on the right. Supplied with a uniquely coded D1T actuator, it offers high-level RFID coding for improved resistance to deliberate manipulation.

Reliable RFID Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST DD211N2-D1T monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. When the uniquely coded actuator enters the sensor's operating zone, the RFID system verifies its identity before enabling the electronic safety outputs, helping prevent machine operation when a protective guard is open or incorrectly positioned.
The ST D series uses redundant electronic technology and is designed for integration with safety modules and safety PLCs equipped for electronic safety outputs. Its non-contact operating principle, high coding level and robust environmental protection make it particularly suitable for modern automated machinery where reliability, resistance to manipulation and reduced mechanical maintenance are important.
Typical Applications
- Machine guard and safety door monitoring.
- Industrial automation and production machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Conveyor and material handling machinery.
- CNC machines and enclosed production equipment.
- OEM machinery requiring high-integrity safety interlocking.
