Description
The SPT02 is specifically designed for the
protection of 24 V proximity sensors. It
implements the reverse polarity and the
overvoltage protection of the sensor power supply
and the power switch overvoltage protection.
It provides a very compact and flexible solution.
Thanks to high performance ST technology, the
SPT02 protects the proximity sensor to the
highest level compliant with IEC 61000-4-2, IEC
61000-4-4 and IEC 61000-4-5 standards.
