Sensor assemblies incorporating a temperature varying resistor provide information regarding the temperature of the operating environment for a sensor or protect the sensor from extreme temperatures. The assembly includes only two conductors—one transmitting current from a power source and another transmitting an output signal. In one embodiment, the assembly includes a sensor and a temperature varying resistor in parallel between the conductors with the output signal including information regarding a value of a variable measured by the sensor and information regarding a temperature of an operating environment for the sensor. In another embodiment, the sensor and temperature varying resistor are in series between the conductors with the output signal including information regarding a value of a variable measured by the sensor and the temperature varying resistor preventing delivery of current to the sensor when a temperature of the operating environment for the sensor meets a predetermined condition.

A wheel-speed sensor (WSS), including: an active pulse-sensor (PS) having a detection-direction (DD), and a housing for the PS; a movement of a pulse-generator in the DD is detectable by the PS; the WSS has an axis and axis direction (AD) defined to be aligned perpendicularly to the DD; the housing has first/second-components, the first-component (FC) being enclose-able and to which the FC is connectable; the PS is on the FC; the WSS has a radial-cable-outlet (RCO), aligned radially to the axis to lead a cable out; the RCO integrally formed with the second-component (SC) so that the cable is led in a different direction; the FC has a first-region (FR), and the SC has a second-region (SR), the FR-contour-circumference having a shape-feature in predetermined-angle (PA) steps around the axis, so that an FC orientation is definable in the PA steps to provide a PA around the axis.

A vehicle rotational speed sensor has a sensor element, a cylindrical sensor housing in which the sensor element is accommodated, an electrical connection cable which is guided out of the sensor housing, and a bend limiting element. The bend limiting element is configured to limit a radius of curvature of the connection cable directly in a region in which the connection cable is guided out of the cylindrical sensor housing.

A body for an acoustic resonance fluid flow speed sensor or an acoustic resonance fluid flow sensor comprising such a body, the body comprising a reflector surface with at least one section that is more hydrophilic than a surrounding section of the reflector surface to promote movement of water from a centre toward an edge of the reflector surface.

A component for a sensor having a sensor element and having an output interface for the outputting of an electrical signal, which is dependent on a physical variable, from the sensor element to the output interface, including—a circuit with at least one first signal path for receiving the electrical signal from the sensor element and for conducting the electrical signal to the output interface, and a second signal path, which differs from the first signal path, for conducting the electrical signal to the output interface,—wherein an activity of the first signal path or of the second signal path is dependent on a position of the component in the sensor.
