TECHNOPLAN TPRC Series Electromagnetic Holder Rectifier Or Controller

Manufacturer: TECHNOPLAN
Model: TPRC series

Electromagnetic Holder Rectifier / Controller

Converts the AC power input into DC power and supplies it to the electromagnetic holder.
In addition, the TPRC-R type features a single reverse-excitation function designed to eliminate residual magnetic holding force.

Operating Conditions for Electromagnetic Holders

[Allowable Temperature]
Use the holder at an ambient temperature of 40°C or less and with a workpiece temperature of 50°C or less. However, 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 can also be manufactured. 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, there is no 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.
