Measurement Columns M20E Series

Image M20E

The M20 Series encoder is the newest addition to the well know M20 measurement equipment line, offering a new set of features for dimensional quality control in production lines.

The M20-4E model allows connection up to 4 incremental transducers (Mitutoyo gage heads, Heidenhain sensors, among others), and the possibility of simultaneous dimensional processing up to 2 different products.

The use of incremental sensors allows very high accuracy, especially in applications that requires long measurement ranges. Additionally, incremental sensors do not require calibration, making the setup process easier and faster.

All models have a high contrast LCD display (2 lines, 16 characters per line), a 101 segment multicolor led bargraph, 6 auxiliary led indications, industrial grade membrane panel, RS232/USB communication interfaces and a digital I/O port (10-bit I/O) for industrial automation.


  • High ruggedness and ease to use. Exceptional electronic and mechanical ruggedness.
  • Integrated data acquisition with support to communicate with commercial SPC software.
  • Direct readout of instantaneous measure, max, min, tir and mean values, for inspection of profile, orientation, run out or position tolerances, without need of complex analysis by the user
  • Simultaneous display of readouts in a high contrast LCD display and 101 segments multicolor led bargraph, allowing ease detection of dimensional run outs or part rejection
  • Independent non-volatile setup up to 100 products (with processing up to 4 transducers on each setup), making the setup process quick and ease even in high diversity part production lines.
  • Compatible with a wide range of linear and angular incremental sensors (from Heidenhain, Mitutoyo, etc).
  • Capable of direct processing for the following units: micrometer, millimeter, centimeter, meter, inch, mils, radian, miliradian, milidegree, degree, milligram, gram, kilogram, ton, kgf, lbf and N (application dependent)
  • Auto detection and setup switch based on sensor signal
  • Digital input filters with adjustable cut frequency
  • Flexible bargraph visualization modes, with option for rollout, zoom-out, static display and center bar
  • Dual-head feature, allowing two independent measurements to run simultaneously with split bargraph and display visualization
  • RS232C and USB communication interfaces for easy data acquisition or connection with commercial SPC software
  • Parallel I/O interface (10-bit) for PLC connection or other automation signaling
  • 5 user configurable key
