Mitutoyo 2046A-11 Dial Drop Indicator 0-100 Metric

Product Description

The MITUTOYO 2046A-11 is a metric dial drop indicator designed for precision dimensional measurement in machine shop, inspection, and toolroom environments. Built to ANSI/AGD Group 2 standards, it delivers 0.010 mm accuracy over a 10.00 mm total measurement range with 1.00 mm per revolution. The jeweled bearing mechanism supports smooth, repeatable stylus travel under a 1.40 N measuring force. The 57.00 mm yellow dial face features a glare-free, scratch-resistant crystal for clear readability under shop lighting. Machinists, quality technicians, and tool-and-die professionals install this indicator for runout checks, surface parallelism, and part-to-fixture alignment tasks.

The 2046A-11 suits residential and industrial machine shops, inspection departments, and production floor applications where metric measurement is required. The 9.52 mm (0.3750 inch) stem diameter fits standard AGD-compatible indicator holders, magnetic bases, and transfer arms. The lug back mount allows secure attachment to indicator posts and surface plate stands. Where tight tolerances demand a traceable, standards-compliant indicator, this unit fits conventional AGD Group 2 setups without adapter hardware.

Key Features

• 0.010 mm dial graduation with 0-100 dial reading scale across a 10.00 mm total range
• Jeweled bearing for low friction, long service life, and measurement repeatability
• Glare-free, scratch-resistant crystal on a 57.00 mm yellow dial face
• Lug back mount with 9.52 mm stem diameter for compatibility with AGD Group 2 holders
• Revolution counter tracks full stylus revolutions during measurement
• Includes limit markers and protective plastic case for storage and transport

Compatibility

Designed for use with AGD Group 2 indicator holders, magnetic bases, and accessory arms accepting a 9.52 mm (0.3750 inch) stem diameter. Conforms to ANSI/AGD standards for Group 2 dial indicators.

Installation Notes

Installation is performed by machinists, metrologists, or quality inspection technicians. Secure the lug back or stem firmly in the holder before zeroing the dial to avoid false readings from indicator movement. Do not exceed the 10.00 mm measurement range or apply side load to the stem, as either condition can damage the jeweled bearing or rack mechanism. Zero the indicator at the reference surface before recording measurements and verify stylus contact force is consistent across measurement points.
