An assembly that includes a target component mounted for rotation about an axis, a sensor mounted adjacent the inner member and directed toward the inner member to measure the rotational speed of the target component and an outer component interposed between the sensor and the target component. Low magnetic permeability of the outer component is assured by appropriate selection of the material, maintaining the concentration of martensite in the outer component below a reference concentration as indicated by certain reference indices such as the Instability Function, and/or by maintaining the temperature at which a stamping operation is performed on the inner member above a pre-determined temperature.

Sensing an operating parameter of a target concealed from a sensor by an interposed component

An automatic transmissions for an automotive vehicle includes a variator of the traction drive type, the variator including an input disc, an output disc, and rollers driveably engaged with the discs and adapted to vary continuously the ratio of the speeds of the output disc and input disc. Each of two planetary gearsets includes a carrier, a sun gear and a ring gear and a set of planet pinions meshing with the respective sun gear and ring gear. Angular variation of the rollers causes the variator to drive the ring gear at a variable speed relative to engine speed and the carrier to rotate in accordance with the speeds of the sun gear and ring gear.
