Proximity sensors work in a similar manner to variable reluctance speed sensors, coming in either hall effect or inductive sensing types. They respond to the presence or absence of a ferrous or non-ferrous target material within or outside a range of distances, providing an electrical output signal to indicate the target location. The housings are typically made of corrosion-resistant stainless steel, with customizable lightweight options available. The envelope and construction can be tailored for various applications.
