Provided with power supply terminal.
Input power of 12 to 24VDC (1A or more).
Insert a gage in the mounting hole
(recommendation: ø9.5_H6) and fix it with the
clamp nut supplied. For this gage, be sure to
hold the knurled section at the middle of the
gage body by hand and tighten the clamp nut
with the special wrench supplied. Ensure that no
force or torque is applied to the cable during this
operation, otherwise damage may be caused.
Optional mounting brackets are available.
Incidentally, when fabricating a mounting bracket,
it is recommended that dimension `B' (shown on
page 32) is 11.5mm.
This counter is dedicated to panel-mount application and is not suited for
direct bench-mount application. Choose an EH counter for bench-mount or
carry-on application.
Only the optional I/O output
connector No.02ADB440 is available
from Mitutoyo. This is because the
number of pins and length of cable
varies with application requirements
and accordingly wiring is better left
for customer’s arrangement.
• The mounting hole shall be machined parallel with the direction of
measurement. Cosine-effect measurement error will occur if the gage is
misaligned with this direction.
• Excessive force in tightening the stem will affect smooth spindle
motion and should be avoided.
• In applications where a Laser Hologage is subject to movement, ensure
that the mounting is designed to avoid the cable being dragged when
in motion.
• Precautions for measurement:
Gage heads have been widely introduced and accepted in various fields of industries. When
it comes to the matter of mounting gage heads onto equipment, however, the problem
encountered is a higher cost involved in fabricating mounting brackets. In order to avoid waste of
this kind, Mitutoyo offers mounting brackets (material: cast iron, FC45, nickel plated) that have
been fabricated with varieties of mounting methods taken into consideration in view of design
and machining. (See page 32.)

• Service air pressure: 0.3 to 0.4MPa
• Lubricating oil: Turbine oil class 1 (ISO VG32)
• Caution: Holding the air cylinder section while mounting gage will
exert force on section A, causing a gage failure. For the same reason it is
essential not to apply force to section A when connecting an air hose to
the gage head.
Laser Hologage
A Laser Hologage can be mounted by inserting its stem in the mounting
hole of a dedicated stand or other equipment.
Recommended mounting hole diameter in fixture: 15mm

• Engage the key wrench (supplied) with the wrench-seat to prevent the
spindle from rotating, grip the contact point with a pair of pliers, then
loosen or tighten it as necessary.
When gripping a contact point with a pair of pliers, insert a piece of felt
or other soft packing between the jaws and the point to protect it from
damage.
• Torque exerted via the spindle on the internal mechanism of a gage
can cause damage to the gage. To avoid this problem, ensure that the
spindle is firmly held with a key wrench before loosening/tightening the
contact point.
• Contact points are interchangeable according to the required
specification of the customer.
About dust / water protection
All gage heads, excluding the LGH and 100mm gage heads, are
protected to IP66 or IP54 (DIN40050/IEC529 standards).
•
The preamplifiers and counters are not designed to provide dust or
water protection. Install them in places where they will not come into
direct contact with water or oil.
•
When an extension cable is used, seal the preamplifier connection and
connectors completely, making sure no portion is left exposed.
•
If the cable cover is damaged, water or other liquids may enter the
gage due to the capillary effect, causing gage failure. If the cable cover
becomes damaged it should be repaired or replaced immediately.
•
Handle the gage with due caution to make sure that the rubber boots
will not be damaged by scuffing, etc. If the rubber boots are damaged,
the gage can no longer be protected from dust or water. When
damage is found, repair or replace the boots immediately.
•
The rubber material used for the boots and seals does not provide
complete protection against coolants and chemicals, which are
becoming increasingly complex in composition. If rubber parts are
found to have deteriorated significantly, contact your nearest Mitutoyo
office.
•
The gage must not be disassembled, since it will break the seals of
various components. Never attempt to disassemble the gage. Doing
so will prevent the gage from functioning to its original specifications.

- To help ensure accuracy, allow 30 minutes warm-up time for the system after
powering ON.
- Allow sufficient time for temperature stabilization for both the gage and
workpieces to be measured.
- Thoroughly clean the contact point and all surfaces to be measured before
measurement to avoid accuracy degradation due to dust or grease.
- Be aware of possible overspeed errors if the contact point is allowed to
drop significantly from surface to surface on the workpiece. Appropriate
measuring procedures should always be used with due consideration for the
part features.
