Why Choose the Pizzato ST DL211N2-L1T Safety Sensor?
The Pizzato ST DL211N2-L1T is a compact RFID-coded non-contact safety sensor designed for monitoring movable 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 for dependable guard monitoring in modern machine safety applications.
The L1T configuration uses a miniaturised high coding level actuator measuring just 53 × 16 × 7 mm. Each high-coded actuator has an individual RFID code, meaning the sensor recognises its specifically associated actuator. This provides enhanced protection against actuator substitution while allowing the compact actuator to be installed where available mounting space is limited.
The ST DL211N2-L1T operates from a 12–24 V DC supply and provides 2 safety outputs OS1 and OS2 together with 1 signalling output O3. The N2 configuration incorporates a 2 m PVC cable, while the DL housing arrangement positions the electrical connection on the left side. Its L1T actuator provides a 12 mm actuation distance for reliable non-contact guard detection.
Key Advantages
- RFID-coded non-contact sensing provides reliable machine guard monitoring without mechanical actuation.

Reliable Safety Monitoring for Industrial Automation
The Pizzato ST DL211N2-L1T uses RFID technology to monitor the position of movable machine guards without physical contact between the sensor and actuator. When the correctly coded L1T actuator enters the sensor's operating zone, the electronic safety outputs provide signals for evaluation by compatible safety control equipment. The individually coded actuator helps provide a high level of protection against deliberate or accidental actuator substitution.
The miniaturised L1T actuator maintains a 12 mm actuation distance while measuring only 7 mm thick, making this configuration particularly useful for compact guards and machinery where installation space is restricted. When correctly incorporated into an appropriate safety architecture, ST D series sensors can support machinery safety systems up to PL e, Category 4 and SIL 3.
