- Measures linear displacement from 0 to 10 mm (0.4 inches), with selectable resolution to 0.1 micrometers
- Slim shape supports high-density installation in close-pitched applications, or in confined spaces
- Differential square-wave output for connection to a compatible display unit (sold separately)
- Photoelectric linear encoders for repeatable measurement
- Protection against ingress of dust and liquid rated at IP66
The Mitutoyo 542-181 LGF linear gauge measures linear displacement from 0 to 10 mm (0.4 inches), with selectable resolution of 1, 0.5, or 0.1 micrometers, and is accurate to 0.8+L/50 micrometers, where L is the displacement measured from 0 to 10 mm.
This linear gauge uses transmission-type photoelectric linear encoders with a maximum response speed of 400 mm/second for repeatable precision measurement, and outputs a 90-degree phase difference square wave with a 0.4 micrometer signal pitch that is equivalent to RS-422A signals for connection to a compatible display unit (sold separately). The gauge can be split-clamp mounted by the thrust stem housing, and the slim shape supports installation in high-density, multi-point applications or use in confined spaces. The gauge has an 8-mm diameter stem, with a 3-mm carbide contact point to help prolong life. Linear ball bearings in the slider unit help smooth spindle strokes, while the electronics housing has an Ingress Protection rating of IP66, for the fullest possible protection against ingress of dust, and protection against liquids up to the force of a high-pressure water jet.
Linear gauges, also called gages, are precision instruments for measuring the displacement of a point on the surface of a workpiece. When several are used together in a fixture they can perfrorm multi-point measurement of the contour of a workpiece and evaluate errors against specified tolerances. In some linear gauges, the degree of displacement is output as a differential square-wave which, when connected to a compatible display unit or process controller, can be identified as a measurement position. Other linear gauges provide digital output for statistical process control, and some may provide both. Linear gauges are typically used in manufacturing for production line and quality control applications, in industries such as automotive and aerospace.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
