Protective hose and shielding hose

Protective hose over leads

The UL-approved protective hoses deployed as standard, which are often fitted with additional tie wraps, are available in different diameters. Spiral protective hose or metal protective hose are also optionally available.
They protect the stepper motor lines in the machines and devices against mechanical damage.

Shielding/Shielding hose

Due to a continuous increase in the powers and frequencies to be switched, the performance of the components and assemblies in their “electromagnetic environment" is always more difficult - also cables must be laid ever more closely - so that the probability for mutual interference increases.
To cope with this development, Nanotec offers a wide variety of different shielding measures. The shielding effect is heavily dependent on the shielding material as well as the shielding construction (optical shield).
Due to the field occurring in the outer space as well as in the inner cable space, a current is created in this shield that, ideally, has no effect on the signal in the cable and, at the same time, should not allow any fields to pass from the inside to the outside.
The braided shield should usually be laid on both sides with a large contact area on the ground potential so that any compensating currents that occur can simply drain away and no big differences in potential or interfering fields are formed. The Nanotec motors in IP54 already include a screw-type cable bushing with optimum EMC protection.
