1. A sensor comprising:
- a cable comprising;
a first conductor, a second conductor, and an extruded crushable layer located between the first and second conductors;
a signal generator connected to the first conductor; and
a signal detector connected to the second conductor, wherein the first and second conductors are adapted to touch and pass a signal from the signal generator to the signal detector upon deformation of the crushable layer.

Abstract
The present invention relates to a contact sensor that detects contact between two objects and includes a first conductor separated from a second conductor by a crushable layer with a predetermined crush resistance. The crushable layer deforms under pressure such that a signal passes between the first and second conductor. Methods of detecting contact are also part of this invention
