Why Choose the Pizzato ST GD420N1-L1T ST G Series Safety Sensor?
The Pizzato ST GD420N1-L1T is a robust RFID non-contact safety sensor designed for reliable machine guarding, safety interlocking and industrial automation applications. Part of the Pizzato ST G series, it combines electronic RFID detection with a coded actuator system to provide dependable monitoring of movable guards, doors and access points without mechanical contact.
The ST GD420N1-L1T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). This flexible electronic architecture makes the sensor suitable for integration into modern industrial safety circuits and automated machinery requiring reliable guard-position monitoring.
Operating from a 24 V DC supply, the ST GD420N1-L1T is designed for dependable operation in demanding industrial environments. Its non-contact sensing principle reduces mechanical wear compared with conventional mechanically actuated interlock switches, supporting long service life and reliable operation on frequently accessed machine guards.
