Final answer:

Sensors that utilize a PNP transistor to switch DC loads are known as current-sourcing devices. They generate current to the load when triggered, often used in industrial control circuits.

Step-by-step explanation:

Sensors that use a PNP transistor to switch DC loads are referred to as current-sourcing devices. In this configuration, when the sensor is activated, it provides the current to the load. It's essential to remember that the PNP transistor works as a current source in this application. A typical example of such an application is a control circuit in an industrial system where signals are generated by these sensors to control DC loads.
