Description
Technical Field
The utility model belongs to the technical field of switches, and particularly relates to an inductive proximity switch.
Background
Proximity switches, also known as contactless proximity switches, are ideal electronic switching value sensors. When the metal detection body approaches the induction area of the switch, the switch can be in non-contact, pressure-free, spark-free and rapid-sending electric instructions, and accurately reflects the position and the stroke of the movement mechanism, and even if the metal detection body is used for general stroke control, the positioning precision, the operating frequency, the service life, the convenience of installation and adjustment and the applicability to severe environments are incomparable with those of a general mechanical stroke switch. It is widely used in machine tool, metallurgy, chemical industry, light spinning and printing industries. The method can be used as a link of limiting, counting, positioning control, automatic protection and the like in an automatic control system. When the mechanical switch is used, an object is required to be contacted, namely, the object reaches a designated position, the proximity switch is arranged at the designated position, and the proximity switch and the object are provided with a signal through the contact point, so that the proximity switch is triggered, and further, a switch signal is transmitted to the control system.
