Electric push rods are usually equipped with limit devices when in use, mainly to achieve program control. Therefore, the correct selection and installation of the device are very important.

The limit devices are usually selected as LX19-001 and LX2-121, and are installed on the same plane as the stroke contact position. However, due to some drawbacks of these two limiting devices, such as poor sealing, low accuracy, and easy damage, they can no longer meet the current needs of program control.

Therefore, a new limit device was developed, and in order to meet the increasingly high requirements, the LJC80A-40J/KS proximity switch was chosen as the limit device for the electric push rod. This is a long-distance, inductive, non buried device with good working ability. In addition, it adopts a fully plastic sealed shell, so problems such as component oxidation and corrosion can also be well overcome. Therefore, this limiting device has become popular among a large number of users.
