5. Proximity Switches

Figure 2.3.5 Configurations of contact type proximity switch [1]

Figure 2.3.5 shows a number of configurations of contact-type proximity switch being used in manufacturing automation. These are small electrical switches which require physical contact and a small operating force to close the contacts. They are basically employed on conveyor systems to detect the presence of an item on the conveyor belt.
