The Pizzato ST DL420H2 is a compact and robust RFID non-contact safety sensor designed for monitoring guards, doors and protective devices on industrial machinery. As part of the Pizzato ST D RFID Safety Sensor series, it uses electronic RFID sensing and solid-state safety switching to provide dependable guard monitoring without the mechanical wear associated with conventional electromechanical safety switches.
The ST DL420H2 configuration provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This versatile input and output arrangement supports integration into modern machine safety architectures, including applications where compatible safety devices are connected in series and machine status information is required by the automation system.
Operating from a 24 V DC supply, the ST DL420H2 uses a durable PUR cable connection and a technopolymer housing with the connection exiting from the left-hand side. The ST D series construction provides IP67 / IP69K protection and an operating temperature range of -25 °C to +70 °C, making this sensor suitable for demanding industrial machinery and automated production environments.
RFID safety sensors such as the Pizzato ST D series monitor movable machine guards without requiring mechanical contact between the sensor and actuator. When an appropriate RFID actuator enters the sensor's operating zone, the electronic safety outputs communicate the guard condition to the associated safety control system, helping prevent hazardous machine operation when a monitored protective device is not correctly positioned.
The ST DL420H2 combines dedicated safety inputs and outputs with signalling and programming functionality, providing machine builders with a flexible solution for modern automated safety architectures. Its sealed technopolymer construction, PUR cable connection and high ingress protection make it particularly suitable for high-cycle machinery and installations exposed to dust, moisture or demanding cleaning processes.
