Limit switches for linear guides are electrical switches that are used to monitor the positioning behavior of linear guides. They are usually mounted at the ends of the guide rail or carriage and are positioned so that they are triggered when the carriage or carriage reaches the end of the guide.
The limit switches can be of various types, for example mechanical limit switches, which are triggered by the contact of a lever or cam, or optical limit switches, which are activated by breaking or interrupting a light beam. Another type of limit switch for linear guides are magnetic limit switches, which are triggered by a magnet moving past the limit switch.
The use of limit switches for linear guides offers several advantages. They enable reliable positioning of the slide or carriage and prevent overtravel of the end point, which can cause damage to the linear guide or other parts of the machine. They can also be used as reference points for positioning, helping to improve the accuracy of positioning.
Limit switches for linear guides are used in many different applications, such as machine tools, assembly and production systems, packaging machines and robots. Depending on the requirements and area of application, different types of limit switches can be selected to ensure optimum functionality and reliability.
