Belt Sway Switch

Liên hệ

Belt Sway Switch, also called a belt misalignment detector, detects belt misalignment and swaying and notifies you.

Brand: Matsushima
Origin: Japan


  1. It is possible to avoid or minimize cargo spillage due to misalignment and sway of loading.
  2. Since there is no spillage, the burden of cleaning work is reduced.
  3. It can prevent belt lugs from hitting the conveyor frame and being damaged, or from causing fires due to frictional heat.


  • Adjustable detection angle
  • Abundant lineup
  • Only worn pulleys can be replaced

Operating principle

When the belt pushes the pulleys due to misalignment or slanting and tilts, a contact signal is sent to detect the misalignment or slanting of the conveyor.

How to use?

  1. Determine the mounting position:

    Install in place where misalignment occurs. Decide on installation location that avoids falling ore from the conveyor or a location subject to large vibrations or shocks.
  2. Mounting:

    Provide a mounting base for Belt Sway Switch. Install Belt Sway Switch so that it is perpendicular to the belt. It is recommended to install cover in case of falling mines.
  3. Wiring:

    The contact signal is a dry contact. Avoid direct input to motors and sequencers, and use magnet conductors or relays.
  4. Adjustment:

    No adjustment is required as it has been adjusted at the factory. However, it is possible to adjust the detection angle in the field if necessary.
