Mitutoyo 2046A-01 Dial Drop Indicator 0-100 Reading

Product Description

The MITUTOYO 2046A-01 is a metric dial drop indicator designed for precision measurement in machining, inspection, and metrology applications. It features a jeweled bearing mechanism and a 55.56 mm (2-3/16 inch) yellow dial face with a 0-100 graduation range and 0.01 mm dial graduation. The lug back mounting style and 9.52 mm (0.375 inch) stem make it straightforward to secure in standard indicator holders and magnetic bases. A built-in revolution counter tracks full rotations across the 10 mm total measurement range, reducing misread errors during repetitive measurement tasks. Accuracy is rated at 0.013 mm per ANSI/AGD standards.

This indicator is suited for surface comparator work, runout checks, flatness verification, and fixture setup in machine shops, quality control labs, and precision manufacturing environments. The metric unit of measure and ANSI/AGD Group 2 rating make it a standard choice for professionals working to tight tolerances in both production and inspection settings. Measuring force is 1.40 N, minimizing deflection of delicate workpieces during contact measurement.

Key Features

• Jeweled bearing mechanism for consistent, low-friction spindle travel
• 0.01 mm dial graduation with 10.00 mm total measurement range
• Built-in revolution counter reduces rotation tracking errors
• Lug back mount compatible with standard indicator holders and magnetic bases
• Yellow dial face for high-contrast readability
• Meets ANSI/AGD standards at AGD Group 2 classification

Compatibility

Designed for use with standard dial indicator holders, magnetic bases, and fixtures that accept a 9.52 mm (0.375 inch) stem diameter. The lug back configuration fits lug-style clamping systems commonly used in metrology and machine shop environments.

Installation Notes

Installation is performed by metrologists, machinists, and quality control technicians. Secure the lug back or stem in a compatible holder before contacting the workpiece to avoid spindle side-loading. Verify the indicator is zeroed and the spindle moves freely through its full range before taking measurements. Do not exceed the rated 10 mm measurement range, as over-travel can damage the internal mechanism.
