The Parker YP20 yoke light is a molded inspection light designed to fit the P-2 series Contour Probe. The light produces substantial close-in illumination for magnetic testing.
The yoke light operates from the induction of the AC magnetic field produced by the yoke. A small coil wound within the molded light housing produces around 12 volts AC which operates the small cylindrical shaped bulb. There are no wiring connections necessary for installation.
