Mitutoyo measuring instruments incorporating these scales provide the signicant benet of being always ready for measurement without the need of preliminary setting after switching on. Electrostatic, electromagnetic and a combination of electrostatic and optical methods are used in implementing this capability but the key enabling feature is Mitutoyo’s patented technology of building absolute positional information into the scale so it can be read at start up. These linear encoders are widely used in Mitutoyo’s measuring instruments as the in-built length standard and their use greatly contributes to the generation of highly reliable measurement data in industry, especially in harsh environments where contamination by cutting uids, coolants and dust must not affect performance.Advantages:1.No count error occurs even if you move the slider or spindle extremely rapidly.2.You do not have to reset the system to zero when turning on the system after turning it off*1.3.As this type of encoder can drive with less power than the incremental encoder, the battery life is prolonged to about 3.5 years (continuous operation of 18,000 hours)*2 under normal use.*1 Unless the battery is removed.*2 In the case of the ABSOLUTE Digimatic caliper (electrostatic capacitance model).IP Codes These are codes that indicate the degree of protection provided (by an enclosure) for the electrical function of a product against the ingress of foreign bodies, dust and water as defined in IEC standards (IEC 60529: 2001) and JIS C 0920: 2003.[IEC: International Electrotechnical Commission]Measuring Instruments Shipped with Inspection CerticateMitutoyo guarantees product quality as a leading precision measuring instrument manufacturer and ships measuring instruments with an inspection certicate that includes inspection data so that customers can use them with condence.Mitutoyo also calibrates the purchased measuring instrument and issues, for a fee, a calibration certicate that proves traceability to the relevant standard.* For the meaning of the inspection marks shown at left, refer to the detailed description of each product.MeasurLink ENABLED marksProducts equipped with the measurement data output function can be connected to the measurement data network system MeasurLink.MeasurLink® is a registered trademark of Mitutoyo Corporation in Japan and Mitutoyo America Corporation in the United States.* For details of the test conditions used in evaluating each degree of protection, please refer to the original standard.FirstcharacteristicnumeralDegrees of protection against solid foreign objectsBrief description Denition0Unprotected—1Protected against solid foreign objects of Sø50 mm and greaterA Sø50 mm object probe shall not fully penetrate enclosure*2Protected against solid foreign objects of Sø12.5 mm and greaterA Sø12.5 mm object probe shall not fully penetrate enclosure*3Protected against solid foreign objects of Sø2.5 mm and greaterA Sø2.5 mm object probe shall not fully penetrate enclosure*4Protected against solid foreign objects of Sø1.0 mm and greaterA Sø1.0 mm object probe shall not fully penetrate enclosure*5Protected against dustIngress of dust is not totally prevented, but dust that does penetrate must not interfere with satisfactory operation of the apparatus or impair safety.6Dust-proofNo ingress of dust allowed.SecondcharacteristicnumeralDegrees of protection against waterBrief descriptionDenition0Unprotected—1Protected against vertical water dropsVertically falling water drops shall have no harmful effects.2Protected against vertical water drops within a tilt angle of 15 degreesVertically falling water drops shall have no harmful effects when the enclosure is tilted at any angle up to 15° on either side of the vertical.3Protected against spraying waterWater sprayed at an angle up to 60° either side of the vertical shall have no harmful effects.4Protected against splashing waterWater splashed against the enclosure from any direction shall have no harmful effects.5Protected against water jetsWater projected in jets against the enclosure from any direction shall have no harmful effects.6Protected againstpowerful water jetsWater projected in powerful jets against the enclosure from any direction shall have no harmful effects.7Protection against water penetrationIngress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.8Protected against the effects of continuous immersion in waterIngress of water in quantities causing harmful effects shall not be possible when the enclosure is continuously immersed in water under conditions which shall be agreed between manufacturer and user but which are more severe than for IPX7.Installation of Main Unit Startup SystemAs a part of the enhancement of our export control system, the large CNC measuring machines (all the CNC Coordinate Measuring Machines, Vision Measuring Systems, and Form Measuring Machines) are now equipped with a Main Unit Startup System (relocation detecting system) before export. This system is designed to take a machine out of operation upon detecting the mechanical shock that accompanies relocation. If you intend to relocate a measuring machine fitted with this system, please contact us beforehand so that our service engineers can assist you. On the other hand, the system may be triggered in the event of a natural event such as a powerful earthquake. In this case, our service engineers will deal with the situation at the earliest opportunity.
