A printed circuit board having conductor tracks formed on one side of a substrate. The substrate is able to be cohesively bonded at a contact face to a cover for protecting the conductor tracks. In this case, the substrate includes a step, which forms a barrier with respect to an auxiliary material for promoting the cohesive bond, in order to prevent any wetting of the conductor tracks with the auxiliary material. A sensor having a printed circuit board for use in a fuel filling level measurement system of a vehicle.

A potentiometer device has a tubular body, an actuation shaft, splines, spline-receiving cavities, a potentiometer, a tubular housing, first and second annular cavities and retention balls. The splines are externally positioned about the actuation shaft. The spline-receiving cavities are internally positioned around the tubular body. The potentiometer has a housing body and a wiper pin. The tubular body is connected to the housing body. The tubular housing and the wiper pin are positioned within the housing body. The tubular housing is connected to the housing body. The wiper pin is mechanically coupled to the actuation shaft. The actuation shaft is removably positioned within the tubular body and the housing body. The first annular cavity internally and radially traverses into the tubular housing. The second annular cavity externally and radially traverses into an output coupling end of the actuation shaft. The retention balls are engaged within the first annular cavity.

A rotary position sensor for measuring the position of a rotating shaft comprises an upper housing and a lower housing arranged to be attached to the upper housing. A barrel is rotationally mounted to the attached upper and lower housings and coupled to the shaft is arranged to be positionable within the attached upper and lower housings by the shaft. A potentiometer component is mounted to the barrel and to an electrical sub-assembly that measures the position of the barrel and in response generates a position signal.

In at least some implementations, a liquid level sensor, includes a liquid level responsive member that moves in response to changing liquid level, an electrically conductive contact associated with the liquid level responsive member, a circuit including a rectifying element and a) one or more conductive elements, or b) one or more resistive elements or c) one or more conductive elements and one or more resistive elements, wherein the contact is arranged to engage at least one of the elements in a, b, or c, and a power supply. The power supply is adapted to provide a voltage to the circuit causing a current flow in a first direction in the circuit wherein the current flows through the contact and to provide a current flow in a second direction in the circuit wherein the rectifying element prevents current flow through the contact.

A rotary controller locking cap including a cap body having a longitudinal axis, a bore extending partially through the cap body along the longitudinal axis such that the cap body has an opening on a first side and is closed on an opposite second side, and an internally threaded portion arranged in the bore at least at the opening. The internally threaded portion is structured and arranged for threaded engagement with a threaded collar of a rotary controller. The bore is structured and arranged to accommodate an output shaft of the rotary controller therein while not contacting the output shaft when the cap body is engaged with the threaded collar. The cap body when engaged with the threaded collar is operable to preclude adjustability of the output shaft of the rotary controller.
