SPT01-335DEE

Automation sensor transient and overvoltage protection
  • active Active

The SPT01-335 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 offering two connections for PNP or NPN sensors as shown in Figure 8 and Figure 9.

Thanks to high performance ST technology, the SPT01-335 protects the proximity sensor to the highest level compliant with IEC 61000-4-2, IEC 61000-4-4 and IEC 60947-5-2 / IEC 61000-4-5 standards.
