15. An elongate capacitive sensor for installation about an opening in a motor vehicle, the opening having at least one corner, the sensor comprising:
- (a) a one-piece extruded non conducting body; and
(b) a first polymeric conductor and a second polymeric conductor embedded in the body, the body configured to substantially maintain a nominal separation distance between the first polymeric conductor and the second polymeric conductor after installation about the corner.

Abstract
A capacitive sensor having a first and a second polymeric conductor are embedded within a non conducting body, wherein the body maintains a fixed separation distance between the first and the second polymeric conductor. The body can include a non conducting web, wherein the web substantially precludes variation in the spacing of the polymeric conductors during use in the intended operating environment.

29-1. The capacitive sensor of claim 28, wherein the polymeric body defines at least a portion of a weatherseal.
- 30. A method manufacturing a capacitive sensor for installation about a motor vehicle opening having at least one corner, the method comprising forming a non conductive web intermediate a first polymeric conductor and a second polymeric conductor to define a separation distance between the first and the second polymeric conductor, the web configured to substantially maintain the separation distance upon installation about the corner.
