Manufacturer: TECHNOPLAN
Model: CEH-D series

Low-Profile Electromagnetic Holder

• Designed to save installation space and reduce the weight of the holder itself.

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; therefore, 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, for other cases, models other than the automatic release type (CEH-R) require a demagnetizing rectifier (TPRC-R) equipped with a reverse-excitation magnetic circuit.
