Grade
Contact numbers: The contact numbers of the control loop contacts are shown in the figure.
Construction Introduction
The limit switch is composed of a main shaft passing through a gear reduction system, a camshaft with an adjustable cam plate combination, and a control system composed of micro switches symmetrically arranged on both sides. The three components are integrated and installed in a housing with a protection level of IP54., its appearance and installation dimensions are shown in the figure.
Adjustment Cam plate Angle
Cam plate Angle: There are two types of cam plates and eight types, that is, the first type includes seven types including Ia, Id...Ig. There is only one type of Category II. Its working angle and corresponding rotation number of the limit switch spindle are shown in Table 4.
