Mitutoyo 174-185A KA-200 3-axis Dro Counter

Product Description

The MITUTOYO 174-185A is the KA-200 3-axis digital readout (DRO) counter designed for machine tool position tracking in precision machining environments. It features an LED display and a built-in calculator function, allowing operators to perform on-the-fly calculations without leaving the machine. Operating on 120 volts, the unit is suited for standard shop power and is installed by machinists or millwrights on lathes and milling machines where repeatable, accurate positioning is critical. The non-linear scale type accommodates a range of encoder inputs. At 4 pounds, the unit is compact enough for bench or machine-mount installation.

The 174-185A is intended for use on manual and semi-automatic machine tools in production and job-shop environments. It supports 3-axis position readout, making it appropriate for knee mills, engine lathes, and similar equipment where X, Y, and Z axis tracking is required simultaneously. The calculator function reduces the need for separate shop calculators during layout and setup work. This unit is a practical fit for tool rooms, machine shops, and maintenance departments running light to medium production work.

Key Features

• 3-axis position readout for simultaneous X, Y, and Z axis tracking
• Built-in calculator function for on-machine arithmetic during setup
• LED display for clear readout in typical shop lighting conditions
• Non-linear scale type for broad encoder compatibility
• 120-volt operation compatible with standard North American shop power
• Compact form factor at 10.24 inches wide, 3.15 inches deep, and 6.57 inches tall

Compatibility

Designed for use with lathe and milling machine applications per manufacturer specifications. Compatible with non-linear scale encoder inputs. Verify encoder interface compatibility with existing machine scales before installation.

Installation Notes

Installation is typically performed by a machinist or qualified millwright. Power down the machine tool and disconnect power at the source before wiring the DRO unit. Mount the display enclosure to a stable surface using the manufacturer-provided hardware, ensuring it is positioned within the operator sightline. Consult the MITUTOYO installation manual for encoder wiring and axis assignment procedures specific to this model.
