• Always lockout and tagout the machine prior to installation
The M100 Stopswitch is a simple inductive proximity shaft speed monitoring device. The self-contained
unit has a single set point, which signals when the shaft has stopped rotating. It can be used for process
control, motion detection and stopped shaft indication.
An inductive sensing device located in the nose of the M100 enclosure will detect a metal target. Ideally,
the target should be a ferrous metal, but non-ferrous metal will be detected at a shorter range. Maximum
range for ferrous targets is 6 mm (15/64 in.) and for non-ferrous targets it is 5 mm (13/64 in.), assuming
a 19 mm (3/4 in.) diameter target. Smaller targets may be used but operating distances will be reduced.
The M100 Stopswitch requires no calibration and provides an output when the shaft has stopped rotating.
The unit incorporates a start-up delay of 4 seconds to allow moving parts to achieve correct speed,
thereafter, if a pulse is not received within 4 seconds an output stopped motion signal is indicated.
