Encoder   \nMitutoyo’s ABSOLUTE method is technology characterized by  \n• Absolute positioning that reads position information on the scale each time,  \n• Not requiring zero-setting.  \nThere are three types of absolute linear encoders depending on whether the method used is electrostatic, electromagnetic, or optical. They are widely used in various measuring instruments as measuring systems endowed with enhanced reliability of measured values.  \nAdvantages:  \n1. No count error occurs even if you move the slider or spindle extremely rapidly.  \n2. You do not have to reset the system to zero when turning on the system after turning it off.*1  \n3. As this type of encoder can drive with less power than the incremental encoder, the battery life is prolonged to about 5 years (continuous operation of 18,000 hours)*2 under normal use.  \n*1: Unless the battery is removed.  \n*2: In the case of the ABSOLUTE Digimatic caliper (electrostatic capacitance model) .  \nis a trademark of Mitutoyo Corporation.  \nIP Codes   \nThese 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.  \n[IEC: International Electrotechnical Commission]  \n（IP：International Protection）  \nIP □□ □ (supplementary letter)  \n\n| Second\u003Cbr>characteristic\u003Cbr>numeral | Degrees of protection against water |  |\n| --- | --- | --- |\n|  | Brief description | Definition |\n| 0 | Non-protected | - |\n| 1 | Protected against\u003Cbr>vertical water drops | Vertically falling water drops shall have no harmful effects. |\n| 2 | Protected against vertical water drops\u003Cbr>within a tilt angle of 15° | Vertically 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. |\n| 3 | Protected against spraying water | Water sprayed at an angle up to 60° either side of the vertical shall have no harmful effects. |\n| 4 | Protected against\u003Cbr>splashing water | Water splashed against the enclosure from any direction shall have no harmful effects. |\n| 5 | Protected against water jets | Water projected in jets against the enclosure from any direction shall have no harmful effects. |\n| 6 | Protected against\u003Cbr>powerful water jets | Water projected in powerful jets against the enclosure from any direction shall have no harmful effects. |\n| 7 | Protection against\u003Cbr>water penetration | Ingress 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. |\n| 8 | Protected against the effects of continuous immersion in water | Ingress 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 . |\n\n| First\u003Cbr>characteristic\u003Cbr>numeral | Deg","cbCaioC9ecYwQLSI","https://ap.wps.com/l/cbCaioC9ecYwQLSI","pdf",14764955,39,"English","# INDEX\n## Product Safety and Environmental Compliance\n## Quality Control\n## Micrometers\n## Micrometer Heads\n## Inside Micrometers\n## Calipers\n## Height Gages\n## Depth Gages\n## Gauge Blocks\n## Dial Indicators, Digital Indicators and Test Indicators\n## Linear Gages\n## Mu-Checker\n## Laser Scan Micrometers\n## Linear Scales\n## Profile Projectors\n## Microscopes\n## Vision Measuring Machines\n## Surftest (Surface Roughness Testers)\n## Contracer (Contour Measuring Instruments)\n## Roundtest (Roundform Measuring Instruments)\n## Hardness Testing Machines\n## Coordinate Measuring Machines\n# Quick Guide to Measurement\n## ABSOLUTE Linear Encoder\n## IP Codes\n## TÜV Rheinland Certification Marks\n## CE Marking and UKCA Marking","[{\"question\":\"What does “ABSOLUTE Linear Encoder” mean in this guide?\",\"answer\":\"It refers to an absolute positioning method that reads position information on the scale each time and does not require zero-setting.\"},{\"question\":\"Why are absolute linear encoders advantageous according to the document?\",\"answer\":\"They prevent count errors even during extremely rapid movement and allow operation without resetting to zero after turning the system back on.\"},{\"question\":\"What are IP codes used for?\",\"answer\":\"IP codes indicate the enclosure’s degree of protection for electrical functions against ingress of solids and water, defined by IEC and JIS standards.\"}]","E11003 - Quick Guide to Precision Measuring Instruments - Quick Guide to Measurement | PDF"]
