Mitutoyo 2119A-11 | Dial Gauge | Flat Back | ANSI/AGD Type | Jeweled Bearing | Graduation 0.001 mm | Range 5 mm
Part No. 2119A-11 | Range 5 mm | Graduation 0.001 mm | Accuracy ±0.01 mm
Product Overview
The Mitutoyo 2119A-11 is a Series 2 dial indicator designed for fine comparative measurement, gauge setting and precision inspection. It provides a 5 mm measuring range with 0.001 mm graduation and a balanced 0-100-0 dial for monitoring movement in both directions from the zero position.
The indicator operates at 0.2 mm per revolution, providing controlled indication throughout the 5 mm measuring range. The supplied specifications state ±0.007 mm accuracy over the first 2.5 revolutions and ±0.01 mm accuracy over the full measuring range.
The 2119A-11 features a 57 mm dial and a lug-back configuration. The lug back allows the indicator to be secured to suitable stands, fixtures and machine setups where a rigid mounting arrangement is required.
The indicator uses a hardened steel stem and spindle, a machine-ground rack gear and four-screw mounting construction. The carbide-tipped contact point provides the specified measuring contact, while jewelled bearings support smooth and sensitive pointer movement. Measuring force is specified as 1.5 N or less.
As the ANSI/AGD configuration, the 2119A-11 uses a 3/8" (Ø9.53 mm) stem and #4-48 UNF contact-point thread. These dimensions distinguish it from the ISO/JIS 2119S-11 configuration, which uses an Ø8 mm stem.
For applications requiring a shorter measuring range, the Mitutoyo 2109A-11 provides a 1 mm range with 0.001 mm graduation.

Who This Product Is Best For
The Mitutoyo 2119A-11 is suitable for quality inspectors, CNC machine setters, toolmakers, maintenance teams and production engineers who require fine comparative measurements.
It is particularly useful for inspection fixtures, height stands, machine setup, alignment checks, runout measurement and comparative inspection where a lug-back mounting arrangement is preferred.
The 5 mm range makes it suitable for applications where the expected movement exceeds the range of shorter 1 mm dial indicators.
How to Use
-
Mount the indicator securely using its 3/8" stem or lug-back mounting arrangement in a rigid stand or fixture.
-
Position the carbide-tipped contact point against the reference or workpiece surface.
-
Apply suitable spindle preload while keeping the indicator within its specified measuring range.
-
Rotate the bezel to establish the required zero reference.
-
Use the limit markers where appropriate to identify the acceptable measurement band.
-
Move or rotate the workpiece and observe the pointer movement on the 0-100-0 dial.
-
Compare the indicated deviation with the applicable drawing, tolerance or inspection requirement.
Keep the indicator securely mounted and avoid exceeding the specified measuring range during use.
