Mitutoyo 350-352-30 Electronic Micrometer Head Flat Spindle

Product Description

The MITUTOYO 350-352-30 is a flat-spindle electronic micrometer head designed for precision dimensional measurement in toolroom, metrology, and machine-tool applications. It covers a measuring range of 0 to 25.4mm (approximately 0 to 1 inch) and delivers a resolution of 0.00005 inches with an accuracy of 0.0001 inches. The 6.35mm-diameter spindle features a carbide measuring face for durability against wear during repeated contact cycles. Built-in digital electronics provide direct data output, allowing integration with SPC data-collection systems. Calibration technicians, machinists, and metrology professionals install this head into fixtures, comparator stands, and custom gauging assemblies.

This micrometer head is suited for precision gauging fixtures in both production and inspection environments. It fits residential shop toolrooms as well as commercial and industrial metrology labs wherever a compact, digitally read micrometer head with data output is required. The rotating spindle and included clamp nut support a range of mounting configurations in custom or standard gauging setups. No specific OEM model compatibility is stated by the manufacturer for this unit.

Key Features

• Flat carbide measuring face resists wear during high-cycle contact gauging
• Digital data output port supports SPC and external data-collection systems
• Rotating spindle with clamp nut included for flexible fixture mounting
• Measurement values displayed in 0.001mm increments on integrated digital readout
• Powered by a single SR44 battery, included in the package

Compatibility

Designed as an OEM-style precision micrometer head for integration into custom gauging fixtures, comparator frames, and precision measurement assemblies requiring a flat-spindle, digitally read head with data output capability.

Installation Notes

Installation is performed by calibration technicians or precision machinists familiar with dimensional gauging equipment. Before mounting, ensure the fixture or stand is free of debris and that all clamping surfaces are clean and burr-free. Use the supplied clamp nut to secure the head; do not overtighten, as this may affect spindle alignment and measurement accuracy. Verify zero calibration after installation before taking production measurements.
