In combination with the corresponding safety modules, the sensors of the ST series are suitable for the monitoring of protective devices on machines without inertia and allow the system in which they are used to reach a safety category up to SIL 3 acc. to EN 62061 as well as up to PL e and Category 4 acc. to EN ISO 13849‑1.
These sensors use RFID (Radio Frequency IDentification) technology and provide high protection against possible manipulation thanks to the uniqueness of the codes transmitted by the actuator.
- Connection in series of several sensors
One of the most important features of the ST series is the possibility of connecting up to 32 sensors in series, while still maintaining the maximum safety level (PL e) laid down in EN ISO 13849‑1.
- Signalling LEDs
ST series sensors feature 4 status-signalling LEDs for quick immediate diagnosis, which highlight the status of each input and output.
- Protection degree IP67 and IP69K
The ST series sensors can be used in all environments where maximum protection degree of the housing is required, and they pass the IP67 immersion test acc. to EN 60529.
- Programmability
Pizzato Elettrica supplies a programmable version of the ST series sensors. With a simple and brief ope‑ ration, the sensor can be programmed to recognise the code of a new actuator.
- Chance to choose between 3 different actuator types
These devices are extremely versatile, for it is possible to choose among 3 kinds of actuators with different fixing and actuating directions.
