Electro Magnetic Holder KE-R แม่เหล็กยึดชิ้นงาน
Small and light, for meeting uses in carrying press material which is not easily released by its own weight ; also for holding hands of industrial robots.
• 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 pressure of the projection at the center of the attractive face. The spring pressure can be adjusted according to workpiece situations. • Electrical control such as a reverse exciting circuit is not necessary. • Quick attach and detach enables speedy automation. • Usable for continuous operation. • Finished by plating. ※ Use these holders for workpieces whose surface where the holder comes in contact is not rough. They are not suitable for thin plates that may be deformed by the pressing force. [mm]

0.12A ※ Projection is provided at the center of attractive face with ∅ 2 × max length 1mm for KE-2R ∅ 2.5 × max length 1mm for KE-3RA and 4RA. ※ If the pressing force cannot release the workpiece smoothly, use a rectifier enclosed in parentheses. ※ RA type: Cord length 0.3 m (0.2-m lead for KE-2R only) ※ The maximum holding power applies to SS400, 10-mm thick, ground-fi nished test piece 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 ˚C or below and temperature of workpieces to hold 50 ˚C 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 steelplates and the holding power relative to various gaps are as shown in the graphs. ※ The maximum holding power is the power that can be obtained under the most favor- able conditions including materials, shapes and finishes of workpieces to hold. Thus, for practical use, choose a suitable model in consideration of a large drop in the holding power depending on situations. Generally, the lifting capacity drops to a half or below of the holding power obtained from the graphs. If you plan to use holders in particular sit- uations such as for workpieces having holes and grooves on the attractive face to disable
the utilization of the whole area or where big acceleration (G) will be applied to work- pieces to be held and transported, please contact us. ※ The electromagnetic holders when powered off still have residual magnetism. 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 a reduction-of-magneti- zation function by reverse excitation, except for the holders equipped with the automat- ic release function. ※ The electromagnetic holders are not of waterproof construction. If waterproof holders are required, please contact us. ※ If you want to use an uninterruptible power supply for a rectifier for electromagnetic holders, please consult with us in advance.

KEP-K5
KEP-7C
• Permanent magnetic holder for long time attraction without trouble of dropping due to power failure. It is turned ON/OFF with electric control. • Magnetic force turns OFF (releases) by power supply control and it is turned ON at all other times. • The interruptible power supply is not required.

How to Use Power source is 24 VDC. When using 4 holders at the same time, connect their wires in series and use them with power of 96 VDC. In this case, a voltage variable rectifi er (e.g.KR-T205) enables adjustment of the demagnetizing voltage (power on amount at OFF) to facilitate operation. Release Only at Power Supply The power-on time must be 5 seconds or less. The power-off time must be 10 times or longer. Residual Magnetism As an inevitable nature of the per manent electromagnetic holder, 3 % to 4 % of the holding power will remain as residual holding power even when it is released. If the weight of the lifted workpiece is lighter that this holding power, it may not be released. In such a case, the workpiece can be released easily by attaching a thin nonmagnetic film on the attractive face. But, the holding power will drop in squared proportion.
Rust and scratches on the attractive face aff ect the holding power adversely. Repair it periodically. Precautions for use
