Small square photoelectric switch

Magnetic proximity switches include eddy current proximity switches, capacitive proximity switches, Hall proximity switches, photoelectric proximity switches, pyroelectric proximity switches, TCK magnetic switches and other proximity switches. Because displacement sensors can be made according to different principles and different methods, and different displacement sensors have different "perception" methods for physical rest, there are the following common proximity switches: wet flow proximity switches This switch is sometimes called inductive proximity switches. It is the use of conductive objects in close proximity to this can generate an electromagnetic field.
