Mitutoyo 2046A Dial Indicator Metric Lug Back ISO Type, Range 10mm

The Mitutoyo 2046A is a precision plunger-type dial indicator with a 10 mm measuring range and 0.01 mm graduation, built to ISO/JIS standards with a metric lug back mounting. This is one of the most widely used dial indicators in the world — the standard choice for machine setup, alignment checking, and dimensional inspection in workshops, quality labs, and production lines across the UAE.

Featuring Mitutoyo's jewelled movement for smooth, backlash-free readings and an O-ring sealed frame that keeps out coolant, oil, and swarf, the 2046A delivers reliable 0.01 mm resolution through its full 10 mm travel. The bezel clamp and lifting lever can be installed on either side without tools, and the revolution counter keeps track of full turns so you never lose your place during long-travel measurements.

✦ Key Features

10 mm Range with 0.01 mm Graduation — Full 10 mm plunger travel with 1 mm per revolution, ideal for checking runout, flatness, height differences, and alignment across a wide range of setups.

Jewelled Movement — Precision-mounted jewel bearings eliminate backlash and ensure smooth, repeatable pointer movement in both directions.

ISO/JIS Lug Back Mounting — Standard 8 mm stem and lug back fit virtually all magnetic stands, holder arms, and fixture clamps without adapters.

O-Ring Sealed Frame — No through-screw holes on the frame. The O-ring seal prevents water, oil, and coolant from entering the movement — essential for shop-floor use.

Bezel Clamp & Lifting Lever — Both mount on either the right or left side without tools. The bezel clamp locks the datum ring, and the lifting lever retracts the plunger for easy positioning.

Revolution Counter — Small sub-dial tracks full revolutions of the main pointer so you can measure across the full 10 mm range without losing count.

📐 Technical Specifications

🏭 Applications

Frequently Asked Questions

What is the difference between the 2046A and the 2046S?
The 2046A is the current production model with the same specifications as the older 2046S. Mitutoyo updated the model designation but the movement, range, and accuracy are identical.

Can I use this indicator on a magnetic stand?
Yes. The 8 mm stem fits directly into any standard magnetic stand with a 3/8" or 8 mm clamp — including the Mitutoyo 7010S-10 sold separately on this store.

Is the 2046A waterproof?
It is splash-resistant thanks to the O-ring sealed frame — no through-screw holes means coolant and oil cannot penetrate the movement. However, it should not be submerged.

What contact point comes with the 2046A?
It ships with a standard flat contact point. Replacement and specialty contact points (ball, roller, needle) are available as accessories.
