Why Choose the Pizzato ST GD820N2-L1T Safety Sensor?
The Pizzato ST GD820N2-L1T is a compact and reliable RFID safety sensor designed for non-contact monitoring of movable machine guards, doors and access points in industrial safety applications. As part of the advanced Pizzato ST G series safety sensor range, it provides dependable guard-position detection for machinery and automation systems.
This safety sensor uses coded RFID technology to identify its associated actuator without mechanical contact, helping eliminate mechanical wear and providing reliable monitoring of machine guards. The ST G series uses redundant electronic safety technology and can achieve high safety performance when correctly integrated into a suitable safety control system.
The ST GD820N2-L1T operates from a 24 V DC supply and is supplied with a 2 m PVC cable. The L1T version incorporates a high-level coded RFID actuator with front fixing, providing an individually coded solution for applications requiring enhanced protection against actuator substitution.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST GD820N2-L1T monitor the position of movable guards without requiring physical mechanical contact between the sensor and actuator. When integrated into an appropriate safety control system, this allows machinery access points to be monitored while reducing mechanical wear associated with conventional safety switches.
The ST G series uses electronic RFID actuator recognition and provides two safety inputs and two electronic safety outputs for integration with suitable safety modules or safety PLCs. Multiple ST G sensors can also be connected in series in compatible safety architectures, providing a practical approach to monitoring several machine guards.
Typical Applications
- Machine guarding and safety doors.
- Industrial automation equipment.
- Production and processing machinery.
- Packaging and material handling machinery.
- Access-point monitoring on automated equipment.
- OEM machine safety systems.
