Digital Scale and DRO Systems

Incremental scale unit
AT402EFeatures• Mounting arrangements are compatible with linear scales supplied by third-party vendors*• Signal conversion adapters are available to provide a variety of industry-standard signal output formats• Absolute Interval Code has enabled implementation of simplified, low-cost ABS system* Please contact your local Mitutoyo Sales Office for more details.

Signal Conversion Adapters for the AT402E
PSU-400EA and PSU-400EV
Connected to the AT402E scale the PSU-400EA outputs a 11μAp-p differential sinusoidal signal, while the PSU-400EV outputs TTL pulses.

Absolute scale unit
AT1100Features• Leverages Mitutoyo’s unique electromagnetic induction technology to provide excellent resistance to oil and water compared withthe optical linear encoder type.
• Innovative shaping and location 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 and sensor even in extremely
severe installation environments• Mounting arrangements are compatible with linear scales supplied by third-party vendors** Please contact your local Mitutoyo Sales Office for more details.
