- PNP output type is used when connecting a load between sensor output terminal and power supply -.
This type is used a lot in Europe from a safety viewpoint because the load is not driven even if somewhere within the wiring connected with the sensor output terminal it is short-circuited. - The following is a typical output circuit diagram of the E2E.
