［Application］
Suitable as a hand of industrial robots for transportation of press
workpieces that are small and light to make them difficult to bereleased by their own weight only.
［Features］●Special cables that have specially high durability against bending
and vibration are used. (Employed in all models except for KE-2R.)●The workpiece is released quickly by the spring force of the
projection in the center of the attractive face. The spring force canbe adjusted according to workpiece conditions.
●The workpiece can be attracted and released smoothly.
●Finished by plating.
●Usable continuously.
※Use these holders for workpieces whose surface where the holder
comes in contact is not rough or has no holes. These holders are
not suitable either for thin sheets that may be deformed by thepressing force.

※Cord length 0.3 m (0.2 m lead for KE-2R only) ※The max. holding power is based on a test piece of SS400, 10 mm thick, ground surface held on the whole area.

※Allowable temperature: The electromagnetic holders KE, permanent electromagnetic
holders KEP and hybrid holders KE-H must be used under the conditions of ambient
temperature 40℃ or below and temperature of workpieces to hold 50℃ or below. For
higher temperature, please contact us.
※The holding power of KE-B, KE-E (D) and KE-RA (R) on various thickness of steel
plates and the holding power relative to various clearance are as shown by thegraphs.
※The max. holding power is the power that can be obtained under the most favorable
conditions including materials, shapes and ﬁnishes of workpieces to hold. Therefore,
for practical use, choose a suitable model in consideration of a large drop in theholding power depending on situations. Generally, the lifting capacity drops to a halfor below of the holding power obtained from the graphs. If you plan to use holders inparticular situations such as for workpieces having holes or grooves on the attractive
face to disable the utilization of the whole area or where big acceleration (G) will beapplied to workpieces to be held and transported, please contact us.
※The electromagnetic holders have residual magnetism even after they are powered oﬀ.
If the mass of the workpiece is greater than the residual holding power, the workpiece
will come oﬀ, but if not, it is usually necessary to use a rectiﬁer equipped with areduction-of-magnetization function by reverse excitation, except for the holders
equipped with the automatic release function.
※The electromagnetic holders are not of drip-proof construction. If drip-proof holders are
required, please contact us.
※If you want to use an uninterruptible power supply as a rectiﬁer for electromagnetic
holders, please consult with us in advance.

Holding power●No fear of accidents by fallen workpieces due to power failure and no heat generated bycontinuous power on. These features make these holders suitable for long-hour holding.
Workpieces are held by a permanent magnet, but its ON/OFF is controlled electrically.
●The electromagnetic release type that keeps the magnetic force oﬀ when power isbeing supplied. Normally, the magnetic force is kept ON.
●An uninterruptible power supply is not required.
●The square type (KEP-K) is suitable for picking up small parts from corners ofcontainers, etc. and picking up doughnut-shaped workpieces.

Precautions for use●The rectiﬁer KR Series and RH Series use electronic PC boards and small relays inside therectiﬁers and therefore, are not suitable for use, for example, on cranes where they are
subjected to vibrations constantly. For installation in places that are subjected to constantvibrations, anti-vibration measures need to be provided. The RH Series external signal input
cables must be shielded cables and must be limited to 10 m long max.
●For failures due to use of holders made by other manufacturers, we may not be able to answer
technical questions. Such use also voids the warranty even if a failure occurs within thewarranty period.

［Application］
These are breakthrough electric products that can make standard electromagnetic holders
respond to higher-speed motion of workpiece handling by robot hands, etc.
［Features］●The residual holding power, a factor to delay workpiece attaching and detaching operations,can be eliminated quickly to speed up the lines that use standard electromagnetic holders.(Thedemagnetizing time may become longer depending on materials of workpieces.)●These controllers can be used to attract and transfer stacked plates one by one or to pick up
parts stored in a bucket one by one by adjusting the voltage.

List of permanent magnetic holders■Type A (Alnico magnet used)
Superior in terms of temperature. The holding power as high as 85% can
be maintained at 350℃ when the holding power at 20℃ is 100%. This
type can be used up to 400℃ intermittently for a short period of time.

■Type B (Samarium-cobalt type rare earth magnet used)

KM-06S

The holding power drops to about 95% at 100℃ and to about 85% at
200℃ when the holding power at 20℃ is 100%. For continuous use,
the upper limit is 150℃ and for intermittent use for a short period oftime, this type may be used up to 200℃.

■Type C (Neodymium rare earth magnet used)※ The holding power may drop when the holder is worked on
additionally. In particular, additional work in the radial
direction has large influence on the holding power andtherefore, must be limited to a minimum necessary scope.

area……Additionally workable.

The holding power drops to about 85% at 50℃ and to about 70% at
100℃ when the holding power at 20℃ is 100%. The upper limit forcontinuous use is 100℃.
