ST DL211N2-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL211N2-E1T Safety Sensor?

The Pizzato ST DL211N2-E1T is an RFID-coded non-contact safety sensor designed for reliable monitoring of guards, doors and access panels on industrial machinery. Part of the Pizzato ST D Series Safety Sensors, it combines electronic RFID actuator recognition with solid-state safety outputs to provide dependable guard monitoring in modern machine safety systems.

The E1T configuration uses a large high coding level actuator that is individually recognised by the sensor, helping provide enhanced protection against actuator substitution in accordance with the principles of EN ISO 14119. Its non-contact operating principle eliminates mechanical switching components at the sensing interface, helping reduce wear in machinery with frequent guard operating cycles.

The ST DL211N2-E1T features a 12–24 V DC supply, 2 safety outputs OS1 and OS2, 1 signalling output O3 and an integrated 2 m PVC cable. The large E1T actuator provides a 20 mm actuation distance, while the DL housing configuration positions the electrical connection on the left side for flexible machine installation.

Key Advantages

• RFID-coded non-contact sensing provides reliable machine guard monitoring without mechanical actuation.
• High coding level E1T actuator helps protect against unauthorised actuator substitution.
• Large E-type actuator provides a generous 20 mm actuation distance.
• 2 electronic safety outputs provide redundant safety-related switching signals.
• Separate O3 signalling output provides status information for machine control systems.
• Integrated 2 m PVC cable supports straightforward fixed wiring.
• Non-contact operation helps minimise mechanical wear and supports a long service life.
• IP67 and IP69K protection makes the ST D series suitable for demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation

The Pizzato ST DL211N2-E1T uses RFID technology to monitor the position of movable guards without physical contact between the sensor and actuator. When the correctly coded E1T actuator is within the sensor's operating zone, the electronic safety outputs provide the signals required by compatible safety control equipment. The high coding level actuator helps increase protection against deliberate or accidental substitution.

Pizzato ST D sensors use redundant electronics and can be incorporated into safety systems capable of achieving up to PL e, Category 4 and SIL 3 when correctly designed and integrated. ST D sensors can also be used in suitable series-connected safety architectures, making the range well suited to machinery with multiple monitored guards and access points.

• Industrial machine guard monitoring.
• Safety doors and movable access panels.
• Packaging and processing machinery.
• Automated manufacturing and assembly equipment.
• Robotic cells and perimeter guarding.
