An extruded capacitive sensor assembly includes multiple sense conductors of unequal length disposed in an upper section of a non-conductive jacket, and a ground conductor disposed in a lower section of the jacket adjacent a panel or carrier to which the strip is affixed. A sensor strip with three sense conductors is formed by extruding a non-conductive jacket having first and second sense conductors in the upper section of the jacket, and severing the first sense conductor to create three unequal length sense conductor segments. Electrical termination to the sense and ground conductors can be made at the point where the first sense conductor is severed, or at the end of the sensor strip. In cases where only two sense conductor segments are needed, the third sense conductor segment is removed or simply un-used.
