Fowler 54-220-777-1 Electronic Micrometer Head 0-25mm

Product Description

The FOWLER 54-220-777-1 is an electronic micrometer head with a 0 to 25mm measuring range and a resolution of 0.00005 inches. It features a flat spindle, a friction thimble for consistent measuring force, and a carbide measuring face for long-term wear resistance. A large LCD display provides clear readings at a glance, and a built-in data output port allows direct connection to SPC data collection systems or compatible devices. This micrometer head is designed for integration into custom fixtures, gauging assemblies, or precision measurement setups in manufacturing, inspection, and metrology environments. Licensed machinists, quality technicians, and tooling engineers are the primary installers and users.

The 54-220-777-1 is suited for precision dimensional measurement applications in industrial and laboratory settings. It is commonly used when building custom gauging fixtures or replacing worn micrometer heads in existing assemblies. The flat spindle configuration is appropriate for measuring flat, parallel, or slightly irregular surfaces. The IP54 ingress protection rating makes this head suitable for light shop-floor use where exposure to coolant mist or dust is a concern. The rotating spindle allows for standard thimble operation during measurement.

Key Features

• 0 to 25mm measuring range with 0.00005-inch resolution for high-precision readings
• Flat spindle design for measuring flat and parallel surfaces
• Carbide measuring face for extended durability and wear resistance
• Friction thimble provides consistent, repeatable measuring force
• Large LCD display for easy reading in shop-floor conditions
• Data output port supports SPC and digital data collection integration
• IP54 ingress protection rating for resistance to dust and light fluid exposure

Compatibility

Designed as a replacement or build-in micrometer head for custom gauging fixtures, inspection tooling, and precision assembly equipment requiring a 0 to 25mm range electronic head with flat spindle geometry.

Installation Notes

Installation is typically performed by a machinist, metrologist, or tooling engineer integrating the head into a custom fixture or gauge body. Secure all mounting clamp surfaces before zeroing the instrument. Power down any connected data acquisition equipment before wiring the data output connection. Follow applicable workshop metrology standards and equipment manufacturer guidelines for fixture mounting and calibration procedures.
