A CYLINDER WITH POSITION FEEDBACK SENSOR

摘要

A cylinder with position feedback sensor, including a barrel (11), a piston rod (12) and piston (15). Markings (M) associated with a central portion of the piston rod (12C) are readable by a sensor (S). In practice, the freedom of slidable movement of the piston rod (12) is such that the markings are retained at all times entirely within the barrel (11) during use so that the external environment cannot influence (e.g. damage) the markings.
