Manufacturer: TECHNOPLAN
Model: CEH series

Electromagnetic Holder

• Magnetic force can be turned ON/OFF remotely by electrical control.
• It can be used for automatic press material feeding, preventing deflection of sheared materials, and in applications ranging from various automated machines to gripping sections of industrial robots.

Duty cycle: Continuous 100% ED

※ The maximum holding force is the maximum value obtained under full-surface contact with a template made of SS400 steel, 10 mm plate thickness, ground-finished surface.

About the Operating Conditions for Electromagnetic Holders

[Allowable Temperature]

Please use the holder at an ambient temperature of 40°C or less and with the workpiece temperature at 50°C or less.
If you need to use it in a higher-temperature environment, please consult us in advance.

[Holding Force]

The holding force varies depending on the holding conditions, such as material, shape, surface finish, and plate thickness.
In addition, if the usage conditions involve cases such as:

• full-surface contact is not possible,
• the workpiece cannot be held at its center of gravity,
• or large shocks are applied during transport,

please select a model with an appropriate safety margin.
Please consult us in advance regarding the operating environment and conditions.

[Waterproofing / Rust Prevention]

Electromagnetic holders are not waterproof. In addition, the holding surface is not treated for rust prevention, so they cannot be used in places such as clean rooms.
However, we can also manufacture specifications suitable for such environments, so please consult us beforehand.

[Residual Magnetic Attraction]

Even after the power is switched OFF, a weak residual magnetic holding force remains in the electromagnetic holder.
If the mass of the held object exceeds this residual magnetic force, there is no problem. However, if it does not, then for models other than the automatic release type (CEH-R), it is necessary to use a demagnetizing type rectifier (TPRC-R) equipped with a reverse excitation magnetic circuit.
