Mitutoyo 2050A-01 Dial Drop Indicator 20mm Plunger

Product Description

The MITUTOYO 2050A-01 is a plunger-style dial drop indicator designed for precise linear displacement measurement in machining, metrology, and inspection applications. It offers a total measurement range of 20.00 mm with a dial graduation of 0.01 mm and an accuracy rating of 0.01 mm, making it suitable for surface comparison, runout checks, and fixture verification. The indicator features a lug back mount for secure clamp-on installation and a yellow dial face for high-visibility readings. A measuring force of 2 N ensures consistent contact without distorting delicate workpieces. Machinists, tool-and-die technicians, and quality control inspectors are the primary users of this instrument.

The 2050A-01 is used across precision manufacturing, machine shop, and inspection environments where repeatable linear measurements are required. Typical applications include checking spindle runout, verifying part flatness, and monitoring fixture travel on milling machines, lathes, and surface plates. The clamp-on base mount type allows it to be mounted to magnetic bases, articulating arms, and fixture posts commonly found in shop and metrology lab settings. Its 0-100 dial reading scale with a 1.00 mm range per revolution simplifies direct reading during incremental measurement routines.

Key Features

• 20.00 mm total measurement range with 0.01 mm graduation for fine resolution
• Plunger-style indicator for direct axial contact measurement
• Lug back with clamp-on base mount type for versatile fixture compatibility
• Yellow dial face for improved readability in shop lighting conditions
• 2 N measuring force minimizes deflection on sensitive workpiece surfaces
• Plain bearing construction for smooth, consistent plunger travel

Compatibility

Designed as an OEM-style dial drop indicator compatible with standard lug-back clamp-on mounting arms, magnetic bases, and articulating holders used in precision measurement setups.

Installation Notes

Installation is performed by machinists or metrology technicians using a compatible clamp-on arm or magnetic base holder. Secure the lug back firmly before zeroing the dial to prevent movement during measurement. Avoid side-loading the plunger shaft, as off-axis force can affect accuracy and wear the plain bearing prematurely. Always handle the instrument carefully to protect the dial face and plunger mechanism from impact.
