ST series safety sensors 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, PL e and Category 4.
These sensors use RFID technology and provide high protection against any manipulation thanks to a unique code transmitted by the actuator. Since they have no mechanical elements, they guarantee a long service life even in applications with frequent operating cycles and under harsh environmental conditions.
Their protection degree is rated IP67 and IP69K and they mantain the maximum safety level PL e, even when connecting up to 32 sensors in series.
It is possible to choose among 3 kinds of actuators with different fixing and actuating directions. This means that the sensors can be installed on all types of machines and guards, both large and small.
