ABSOLUTE Linear Encoder
Mitutoyo's technology has realized the absolute position method (absolute method). With this method, you do not have to reset the system
to zero after turning it off and then turning it on. The position information recorded on the scale is read every time. The following three types
of absolute encoders are available: electrostatic capacitance model, electromagnetic induction model and model combining the electrostatic
capacitance and optical methods. These encoders are widely used in a variety of measuring instruments as the length measuring system that can
generate highly reliable measurement data.
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

.
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 20,000 hours)

under normal use.
*1: Unless the battery is removed.
*2: In the case of the ABSOLUTE Digimatic caliper.
• The electromagnetic-induction-type absolute encoder is patent-protected in Japan, the United States, the United Kingdom, Germany, France, India and China.
• The absolute encoder combining the electrostatic capacitance and optical methods is patent-protected in Japan, the United States, the United Kingdom, Germany,
Switzerland, Sweden and China.
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) and JIS C 0920. Due to ongoing development of new length measuring systems, Mitutoyo builds metrology products qualified to protection codes IP65, IP66
and IP67, which signifies that these products may be used in hostile environments.

Independent Confirmation of Compliance
IP65, IP66 and IP67 protection level ratings for applicable Mitutoyo products have been independently confirmed by the German accreditation organization, TÜV Rheinland.

Conformance to CE Marking
In order to improve safety, each plant has programs to comply
with the Machinery Directives, the EMC Directives, and the Low
Voltage Directives. Compliance to CE marking is also satisfactory.
CE stands for Conformité Européenne. CE marking indicates
that a product complies with the essential requirements of the
relevant European health, safety and environmental protection
legislation.
RoHS Directive Compliance
The RoHS directive* is a set of European regulations for the use of certain hazardous substances. Since July 1, 2006, selling specified
electronic equipment containing more than the regulation amount of the specified six substances (lead, cadmium, mercury, hexavalent
chromium, polybrominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE)) is prohibited in Europe.
The scope of the RoHS directive is based on the 10 categories in the WEEE** directive. However, medical devices and monitoring and
control instruments are excluded.
Mitutoyo is actively promoting environmental protection by developing RoHS-compliant products.
* RoHS directive:
Directive of the European Parliament and of the Council on the restriction of the use of certain hazardous substances in electrical
and electronic equipment
** WEEE directive: Waste Electrical and Electronic Equipment Directive
