Columbia Marking Tools’ updated Mite-E-Mark air impact marker features additional stroke length, integrated position sensors and a low-maintenance, non-lube feature. This air impact marker is used for marking lot codes, acceptance marks or machine ID codes on metal and plastic parts.
The marker is compact, and in its smallest configuration, is 3″ long with 1″ of approach stroke from the retracted position to the point of part marking. The marker also offers an additional option with a longer approach stroke. This added feature also has more force. The 2″ approach stroke offers 220 lbs of impact force at 80 psi.
One of the more recent additions to the marker is the integrated position sensor. This electronic indicator is installed internally and is able to detect when the marker is in the retracted position. This option is useful for manufacturers who prefer to work in “lights-out” environments, the company says.
The non-lube version of the air impact marker features permanent lubrication and improved seals. This combination provides a system that no longer requires constant maintenance and additional lubrication, the company says.
