Mitutoyo 543-796-10 Electronic Drop Indicator

Product Description

The MITUTOYO 543-796-10 is an electronic drop indicator designed for precision dimensional measurement in machining, inspection, and metrology applications. It measures from 0.0000 to 0.5000 inches (0 to 12.70 mm) with an accuracy of plus or minus 0.0001 inches (0.003 mm). The straight connection type allows direct mounting to standard indicator holders, magnetic bases, and transfer stands. Machinists, quality control technicians, and toolroom professionals use this instrument to check runout, flatness, and part-to-part variation on machine tools and inspection fixtures. The electronic output provides a clear digital readout, reducing interpretation error compared to dial-type indicators.

This drop indicator suits residential shop environments, production floors, and quality labs where repeatable linear measurement is required. It is well suited for surface plate work, lathe runout checks, milling machine setup, and CMM-adjacent hand measurement tasks. The 0.5000-inch range covers the majority of common setup and inspection tolerances encountered in general machining and precision manufacturing work. A measuring force of 2.5 newtons keeps contact pressure consistent, helping protect delicate workpiece surfaces during gaging operations.

Key Features

• Electronic digital readout eliminates analog interpolation errors
• Measurement range of 0.0000 to 0.5000 inches (0 to 12.70 mm) suits most setup and inspection tasks
• Accuracy of plus or minus 0.0001 inches (0.003 mm) for high-precision tolerance verification
• Straight connection type for direct compatibility with standard indicator holders and magnetic bases
• Measuring force of 2.5 newtons minimizes contact pressure on sensitive surfaces

Compatibility

Designed as an OEM-style drop indicator for use with standard indicator holders, transfer gages, and magnetic base setups common in machining and quality inspection environments.

Installation Notes

Mounting and setup should be performed by a qualified machinist or metrology technician familiar with indicator gaging procedures. Secure the indicator firmly in the holder to prevent slip or backlash errors before zeroing the instrument. Ensure the spindle axis is aligned perpendicular to the measurement surface to avoid cosine error. Do not exceed the stated measuring range or apply lateral force to the spindle, as this can damage the internal sensing mechanism.
