Mitutoyo 543-792-10 Electronic Drop Indicator 0.5 in

Product Description

The MITUTOYO 543-792-10 is an electronic drop indicator designed for high-precision dimensional measurement in metrology, machining, and quality control applications. It delivers a measurement range of 0 to 0.5 inches with an accuracy of 0.0001 inches, making it suitable for work where tight tolerances are critical. The lug back mounting configuration allows secure attachment to magnetic bases, indicator holders, and transfer stands. Powered by a single SR44 battery — included — the unit provides digital output without the reading ambiguity of a dial face. The contact point is solid carbide for wear resistance during repeated probing cycles.

This indicator is used in dimensional inspection setups on machine tools, surface plates, and fixture rigs in both production and tool-room environments. Machinists, quality technicians, and metrologists use it for runout checks, flatness verification, and part-to-part comparison measurements. The drop-style body allows the spindle to travel vertically downward, which suits many surface and bore measurement setups where a standard back-plunger style would be awkward to mount.

Key Features

• Measurement range of 0 to 0.5 inches with 0.0001-inch accuracy
• Solid carbide contact point for extended service life under repeated use
• Lug back mount for compatibility with standard indicator holders and magnetic bases
• Digital electronic readout eliminates parallax error inherent in dial indicators
• Battery powered using a single SR44 cell, included in the package
• Meets ANSI standards for dimensional measurement instruments

Compatibility

Designed as an OEM-style electronic drop indicator for use with standard lug back indicator mounting hardware, magnetic bases, and universal indicator holders common in machine shop and inspection room setups.

Installation Notes

Installation is performed by machinists or quality technicians familiar with precision measurement equipment. Secure the lug back to a rigid holder or magnetic base before zeroing the instrument to prevent measurement error from movement. Avoid side-loading the spindle during use, as lateral force can affect accuracy and wear the spindle bore prematurely. Handle the contact point with care — carbide is hard but brittle and can chip if struck against a hard surface.
