Defying Conventional
WisdomNewly released
Scale Unit

Outstanding Environmental ResistanceThis scale unit leverages Mitutoyo's unique electromagnetic induction technology to provide excellent
resistance to oil and water compared with the optical linear encoder type, elevating the ABS AT1100 to
the level of a highly reliable NC machine-tool scale suitable for tough shop floor conditions.

Robust Dustproof/Waterproof Structure
Additional factors in providing the high performance of the ABS AT1100 are the innovative shaping andlocation of the detector track in the aluminum frame and the extreme coolant resistance of the track-sealmaterial. Together these combine in a highly effective first defence against contamination of the scale andsensor even in extremely severe installation environments.

Approximately
0.4mm

World's Largest Air Gap
The sensor-to-scale air gap is approximately 0.4mm, around 4 times as wide as that of the conventional
optical or electromagnetic induction design. This is yet another factor that makes issues due to dust or oil
contamination unlikely to arise. This air gap is actually the largest in the world for a machine-tool scale.
