Encoders
Mitutoyo DROs paired with linear scales deliver an unbeatable combination of precision, speed and ruggedness for machine tool and positioning applications. Mitutoyo linear scales are available in several different types, sizes, response speeds and IP protection ratings to meet the demands of any application. Paired with intuitive DRO displays featuring multi-axis readouts, preset macros, switchable inch/metric resolution and SPC data output, operators get real-time, repeatable feedback to help speed up set-up times, reduce manual calculation errors and improve overall machining cycle times.

Frequently Asked Questions
Have Question? We are here to help
How do Mitutoyo products support OEM applications?
Mitutoyo offers a wide range of components specifically for OEMs to integrate into their own equipment and systems. This includes high-precision linear encoders, sensors, and miniature microscope units. We work with OEMs to develop custom solutions that seamlessly integrate with their production lines, providing the core measurement technology they need.
What types of sensors and encoders does Mitutoyo offer?
We offer a variety of sensors and encoders designed for different applications, including:
-
Linear Gauges: For accurate linear displacement measurement in quality control applications.
-
Laser Scan Micrometers: For non-contact measurement of small or delicate parts.
-
Non-Contact Line-Laser Sensors: Designed for high-speed part measurement in automated systems.
-
Linear Encoders/Scales: Both optical and electromagnetic types for position feedback in machine tools and precision stages.
What is the difference between an optical and an electromagnetic linear encoder?
An optical linear encoder uses a glass scale with precise gratings. A light source and a light-receiving device detect changes in light intensity as the scale moves, converting this into a displacement value. An electromagnetic linear encoder uses electromagnetic induction and is highly resistant to environmental contaminants like coolant, oil, and dust, making it ideal for harsh workshop environments.
What are the benefits of using a Mitutoyo DRO system on my machine to
Mitutoyo DRO systems dramatically improve machining accuracy and efficiency by providing:
-
Clear, High-Resolution Display: Digital counters show the precise position of the cutting tool or workpiece, eliminating the need for manual calculations.
-
Zero-Setting at Any Position: You can set a zero point at any location on a workpiece, simplifying complex operations.
-
Versatile Functions: Many DRO counters feature one-touch macro keys and functions to simplify operations like bolt-hole circles, line holes, and angular measurements.
Can I use Mitutoyo DRO scales with a different brand of digital readout counter?
Mitutoyo scales and counters are designed to work together as a system for optimal performance and accuracy. While some cross-compatibility may be possible, it is not universally guaranteed due to differences in wiring, voltage, and signal protocols. We recommend using a complete Mitutoyo DRO package for the most reliable and accurate results.
