Environment-Resistant Digital Gage

LINEAR GAGE LG100 SeriesCompact-type Counter EJ Counter

Catalog No. E13021(2)Can be used inline or in measurement rooms

Best-in-class precision and environmental resistance.
Enables real-time measurement and data management

Linear Gage LG100 SeriesHigh accuracy
Precision and accuracy demanded by the automated assembly and inspection markets,are guaranteed. Thanks to our expertise as a manufacturer of measuring instruments,
repeatability in the full measurement range (2σ) and narrow-range precision are also
guaranteed.

542-190/542-191/542-192(10 mm stroke)

CounterIndustrial interface

Environment resistanceSliding durability of more than 50 million times*, with protection level of IP67G. Highly
oil-resistant material is used in the rubber cap and cable sheath, so it can be used even inharsh environments.

542-193/542-194/542-195(25 mm stroke)* 10 mm range models (Actual value from in-house tests)

Function of reference point detection
Reference point signal output functions are featured throughout this series. When
incorporating into a device the master setting value is easy to set and is retained after
shutdown. Re-setting the origin is possible when there are problems such as excessive
speed, ensuring excellent reliability.

542-196/542-197(50 mm stroke)

Measurement

Can be connected with 2 types of counter
The ideal counter can be selected according to the application it can be connected to acompact counter (EJ counter) suitable for inline use or building into a device or amultifunctional counter (EH counter)* suitable for use in measurement rooms.

Interface unit
CC-LinkUSBPLC* A conversion plug is required for connecting to multifunctional counter (EH counter).

Combining small form and ease of use
High-speed and space-saving, delivering production site visualization, improved
productivity, and information feedback. Up to 8 compact counters (EJ counters) can belinked providing the capacity to connect up to 16 gages. On a DIN rail, each unit can beconnected directly without using cables, so it takes up minimal space. All linked units andgages can be driven by a single power source.

CC-Link connection, USB connection
Data can be output through an industrial interface (CC-Link) by linking a compact counter(EJ counter) with an interface unit. Constant data monitoring and positional management
are performed. A USB interface is also provided for easy connection with a computer.

Data management

Note: The range of interfaces is set to be expanded in the near future.

Inter-axial calculation function
Enables sum difference operations between 2 gages connected to the same counter.
Functions such as tolerance judgment and peak hold are also included.

Can be used in various production settings
