ST DD821N10-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD821N10-E1T Safety Sensor?

The Pizzato ST DD821N10-E1T is a robust RFID safety sensor designed for non-contact monitoring of guards, doors and protective devices on industrial machinery. As part of the advanced Pizzato ST D series, it combines coded RFID detection with electronic safety outputs to provide dependable guard monitoring for machine builders, OEM equipment and industrial automation systems.

The ST D series uses RFID technology to detect a coded actuator without requiring physical contact between the sensor and actuator. This non-contact operating principle helps reduce mechanical wear on frequently operated guards, while coded actuator recognition provides enhanced protection against manipulation compared with conventional uncoded sensing technologies.

The ST DD821N10-E1T is designed for integration into 24 V DC industrial safety systems and features an integral 10 m cable for direct connection to machine wiring and compatible safety control equipment. Its electronic architecture makes it suitable for modern machinery requiring reliable non-contact guard detection and straightforward integration with safety modules or safety PLCs.

Reliable RFID Guard Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST D series monitor movable guards by electronically detecting a coded actuator rather than relying on mechanically operated contacts. When the actuator reaches the required position, the sensor communicates the guard state to compatible safety control equipment, allowing hazardous machine functions to be controlled according to the safety-system design.

The non-contact operating principle is particularly useful on machinery subject to frequent access, vibration and repeated production cycles. With no mechanical actuator entering the sensor housing, physical wear is minimised, while coded RFID detection provides increased resistance to deliberate bypassing and helps maintain dependable guard monitoring in industrial automation systems.

Typical Applications

• Machine guard and access-door monitoring.
• Packaging and production machinery.
• Automated assembly systems.
• Material handling and conveyor equipment.
• Robotic and automated production cells.
• Processing and manufacturing machinery.
• OEM machinery and integrated industrial safety systems.
