The invention relates to a sensor comprising a sensor element () for detecting a physical variable, said sensor comprising two electric contact surfaces (), and comprising a sensor body (), on one end of which the sensor element () and on the other end of which a contact carrier () is located, wherein the contact carrier () supports at least two insulation displacement contacts () suitable for producing an insulation displacement connection () to an electric connecting cable (), wherein each contact surface () is connected to an insulation displacement contact (). The invention also relates to a sensor assembly. The combination of the insulation displacement technology with the sensor makes it possible for the sensor and the cable tree of a motor vehicle, for example, to be contacted in a simple manner.

Sensor and sensor assembly

The temperature sensor is particularly suitable for a fever thermometer which has outer dimensions of, for example, 4 mm diameter and 40 mm length. To provide the requisite stiffness, the outer sleeve is made of stainless steel or specialty steel of thin walls, for example less than 0.1 mm wall thickness, closed at one end, and the temperature sensor is positioned essentially exposed, and naked at the end of a positioning body formed of two half-sections of low-density foam material, in which a longitudinal groove is formed, through which the connecting wires of the temperature sensor extend. The longitudinal groove can be filled by a springy element, for example unitary with one of the half-sleeves, or a separate positioning rod. The connecting ends of the sensor conductors can be connected to a coaxial cable, and the end portion can have a handle plastic-molded thereabout. The exposed positioning of the sensor, adhesively connected to the inner end of the sensor tube, provides for low heat capacity, high heat transfer, and the foam filling additionally contributes to heat sensitivity.
