pendolo

Italian to English Tech/Engineering Automation & Robotics

I don't quite understand how to translate "pendolo" below:

Errore Generale: Sensore Anticollisione (pendolo) Intervenuto

I have found "pendulum" in my research, but I thought maybe "osscilating" or "pending" might be the meaning... I also cannot tell if this "pendolo" in this context is an physical object in the shape of a pendulum, or whether it is describing the sensor's actions...
