Hybrid Electromagnetic Holder

• This holder combines the magnetic force of a permanent magnet and an electromagnet, providing a high holding force despite its compact size.
• By switching between energized, de-energized, and reverse-energized states, the holding force can be controlled in three levels: strong, medium, and off. Therefore, you can select the appropriate holding level according to the application.
• When the power is turned off, the permanent magnet continues to provide holding force. Therefore, the holder can be used for magnetic brakes, stopper components, and handling fixtures/tools. In addition, reverse energization allows the magnetic holding force to be switched OFF.

Duty Cycle: Continuous 100% ED

※ The maximum holding force is the maximum value obtained with full-surface contact using an SS400 steel test plate, 10 mm thick, with a ground-finished surface.

Operating Conditions for Electromagnetic Holders

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

[Holding Force]
The holding force varies depending on conditions such as the material, shape, surface finish, and plate thickness of the workpiece. In addition, if full-surface contact is not possible, the workpiece cannot be held at its center of gravity, or strong impacts occur during transport, select a model with an appropriate safety margin. Please consult us in advance regarding specific operating conditions.

[Waterproofing / Rust Prevention]
The electromagnetic holder is not waterproof. Furthermore, the holding surface does not have a rust-prevention treatment, so it cannot be used in environments such as clean rooms. However, custom specifications suitable for such environments are also available. Please consult us for details.

[Residual Magnetic Attraction]
Even after switching the power OFF, a small amount of residual magnetic holding force remains. If the mass of the held object exceeds this residual magnetic force, it will not cause a problem. However, in other cases, models other than the automatic release type (CEH-R) require a demagnetizing rectifier (TPRC-R) equipped with a reverse-excitation magnetic circuit.
