Mitutoyo 350-351-30 Electronic Micrometer Head Flat Spindle

Product Description

The MITUTOYO 350-351-30 is a flat-spindle electronic micrometer head designed for precision measurement and positioning applications in metrology, machine tooling, and inspection environments. It covers a measuring range of 0 to 25.4mm with a resolution of 0.00005 inches and an accuracy of 0.0001 inches, making it suitable for high-precision work where repeatable readings are critical. The spindle diameter is 6.35mm and the overall length is 156.5mm. Measuring faces are carbide for long service life. Built-in data output allows readings to be transmitted to external recording equipment. Licensed machinists, metrologists, and precision instrument technicians are the primary installers and users.

This micrometer head is used in precision machining setups, fixture building, inspection stations, and laboratory measurement environments. It is suited for both bench and machine-mounted applications where a flat spindle contact face is required. The rotating spindle allows for standard micrometer-style adjustment. Measurement values are displayed in 0.001mm increments on the integrated electronic display. This head is appropriate for industrial and toolroom settings where both analog feel and digital output are needed simultaneously.

Installation Notes

Installation and integration of this micrometer head should be performed by qualified machinists or metrology technicians familiar with precision instrument mounting. Ensure all machine motion is stopped and any powered equipment is de-energized before mounting or adjusting the head. Use appropriate clamping hardware compatible with the spindle and housing dimensions to avoid damaging the precision spindle or measuring faces. Follow equipment manufacturer guidelines for data output wiring when connecting to external SPC or logging systems.
