Sensor for measuring the separation (E) of fingers (1) of a tool, essentially including a framework (3) carrying a stop (4) for one of the fingers (1a) and a turning lever (7) pushed back by the other finger (1b). Gearing (11, 12), actuated by the lever (7), makes it possible to measure the separation of the fingers. This invention is designed to operate in a hostile environment and its advantages are its robustness, its simplicity and the precision for the measurements. <IMAGE>
