The Ramsey Pro-Line Belt
Misalignment Switch monitors the operation of conveyor belts and
alerts you in the case of a run-off or misaligned belt. The
displacement of its actuating arm by a misaligned belt causes a
cam to operate a micro-switch with DPDT contacts, which may be
used for interlocking, conveyor shut-down and/or alarm/annuciation.

Run-Off Switches are mounted on the top or bottom of the
conveyor stringers with the actuating arm adjusted to the outside
edges of the belt.
Under normal conditions with the belt trailing properly, the
edge of the belt clears the actuating arms by 1" or more
(adjustable by switch positioning).
If the belt skews or runs-off contacting actuating arm,
displacing it from the arm's normal vertical position, one or more
of the microswitches are contacted.
Displacement of the actuating arm causes a cam to operate a
microswitch with DPDT contacts. These contacts may be
used for interlocking, conveyor shut-down and/or
alarm/annunciation.
