Mitutoyo 04AZA721 Electronic Micrometer Head

Product Description

The MITUTOYO 04AZA721 is an electronic micrometer head designed for precision measurement applications in metrology, machining, and quality control environments. This replacement-style component integrates an electronic readout mechanism into a standard micrometer head form factor, allowing technicians and machinists to obtain digital displacement readings with high accuracy. At 0.15 pounds, the unit is compact and suited for bench-top or fixture-mounted measurement setups. No clamp nut is included with this part, so the installer should confirm that mounting hardware is sourced separately before beginning installation.

Electronic micrometer heads of this type are used in precision dimensional inspection, fixture gaging, and custom measurement instrument builds. They are appropriate for industrial metrology labs, machine shops, and quality assurance stations where repeatable linear measurement is required. This part is catalogued as a replacement or web-only SKU, meaning it is typically sourced to service or upgrade existing measurement equipment rather than as a standalone new instrument purchase.

Key Features

• Electronic readout integrated into micrometer head for digital displacement measurement
• Compact form factor at 0.15 pounds for fixture or bench-mount applications
• No clamp nut supplied — confirm mounting hardware availability before ordering
• Sold individually as a single-unit replacement part
• Catalogued as a replacement and web-only SKU for service and upgrade use

Compatibility

Designed as an OEM-style replacement electronic micrometer head for precision measurement instruments and gaging fixtures requiring a compatible Mitutoyo-sourced head assembly.

Installation Notes

Installation of electronic micrometer heads should be performed by a qualified metrology technician or machinist familiar with precision instrument assembly. Confirm the receiving fixture or instrument is fully powered down and secured before removing or installing the head. Clamp nut hardware is not included and must be sourced separately prior to mounting. Handle the spindle and measuring faces with care to avoid contamination or damage that would affect measurement accuracy.
