ST DL820N10-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL820N10-D1T Safety Sensor?

The Pizzato ST DL820N10-D1T is an advanced RFID-coded non-contact safety sensor with actuator from the Pizzato ST D series, designed for reliable monitoring of guards, doors and movable protective devices on industrial machinery. RFID technology enables electronic guard detection without mechanical actuator insertion, helping minimise wear while providing dependable safety interlocking in applications with frequent operating cycles.

Operating from a 24 V DC supply, the ST DL820N10-D1T provides two OS safety outputs, one inverted signalling output, two IS safety inputs and one programming input. Its redundant electronic architecture supports integration into sophisticated machine safety systems and, when correctly integrated, can contribute to safety functions up to PL e / Category 4 and SIL 3.

This model combines a 10 m integrated PVC cable with left-hand output connection and a D1T high-level coded RFID actuator. The D1T actuator provides a 12 mm actuation distance and measures 45 × 25 × 18 mm, with front and lateral fixing options. The technopolymer sensor housing provides IP67 / IP69K protection for demanding industrial environments.

Key Advantages

• Non-contact RFID safety sensing reduces mechanical wear and supports a long operating life.
• D1T high-level coded actuator provides increased protection against actuator substitution and manipulation.

Advanced RFID Guard Monitoring for Industrial Automation

The Pizzato ST D series electronically monitors movable machine guards without requiring mechanical switching between the sensor and actuator. When the correctly coded actuator enters the safe activation zone, the sensor enables its safety outputs, allowing the associated machine safety system to verify that the protective device is correctly positioned before hazardous machine functions are permitted.

The ST DL820N10-D1T combines high-level RFID coding, two safety inputs, two safety outputs, an inverted signalling output and a programming input in a robust non-contact sensor. The D1T actuator's individual high-level coding provides enhanced resistance to inappropriate actuator substitution, while the 10 m integrated cable is particularly useful where the sensor must be wired directly over longer distances to a control enclosure or safety system.

Typical Applications

• Machine guard and access-door monitoring.
• Automated production and assembly equipment.
• Packaging and processing machinery.
• Robotic cells and perimeter guarding systems.
• Conveyor and material handling equipment.
• Large machinery requiring extended sensor cabling.
• OEM equipment requiring high-level coded safety interlocking.
