Motion control has emerged as one of the most dynamic technologies in manufacturing. The current shift from mechanical control systems towards electronic servo control systems promises to increase process speeds by 50% or more, depending on application. The transfer and assembly lines have had a powerful impact in automating our factories with the primary goal of reduction of labour content while holding on to the financial justification labelled as economy of scale. Motion controllers are components that range from ON/OFF devices with simple linear controllers to complex, user programmable modules that act as controllers
within complex integrated multi-axis motion systems. Applications include all types of industrial processing, packaging, and machining/forming operations. This thesis will focus on analysis of basic motion control theory, sensors and actuators used in
motion control, adapting fieldbus technology in motion control systems, and developments, trends and application of motion control technology in different engineering disciplines.

Excerpt from the Book
2.2 PROXIMITY SENSORS
Proximity sensors detect the presence of nearby objects without any physical contact. Proximity sensors often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object sensed is referred to as the proximity sensor target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor requires a metal target. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object.
The following sections describe in details the various types of proximity sensors commonly in use, their principle of operation and applications.
2.2.1 Inductive proximity sensors
Inductive proximity sensors only detect the presence of metallic objects with the use of its electromagnetic field. They operate under the electrical principle of inductance. Inductance is the phenomenon where a fluctuating current, which by definition has a magnetic component, induces an electromotive force (emf) in a target object.
