How shielded cable braid helps with EM
compliance
Shielded cable braid from Warth International addresses the issue of the protection of data and power cables either entering a device, or used to connect internal circuitry or motors
The use of electromagnetic shielding gaskets is now common place within the electronics industry, with the need to conform to the emc directive paramount to any manufacturer looking to trade within Europe, and the United States One area of compliance that can often be overlooked is the protection of data and power cables either entering a device, or used to connect internal circuitry or motors

Tiny, conformable grounding pads from Warth International are being used to address one of the primary concerns when designing the electronics within a small mobile device
Shielded cable braid from Warth International addresses this issue.
The braid, ZCS-13, is based on standard nylon cable sheathing, but is uniquely plated with a silver based coating which gives it excellent electrical properties, allowing it to protect inserted cables against spurious electromagnetic signals or crosstalk from adjacent devices.This is essential for unprotected data cables used in an environment where strong electromagnetic signals are present, for example within an electrical drive or motor unit controlled by a microprocessor based device.
The braid can be either pulled to reduce, or expand to increase the aperture size of the sheath, to accept cables or looms of up to 20mm diameter, or to clasp diameters down to 8mm for smaller applications.
Essential to the performance of the shielding braid is correct earthing and this is provided by securely connecting the ZCS-13 to the metal chassis or ground of the unit.
Where a cable is entering a device this can be done by the use of Warth emc cable glands.
The sheathed cable is inserted through the cable gland and a locking mechanism within the gland securely holds the shielded braid against an electrically conductive seal, which is connected to the chassis of the unit.
Unlike other cable glands, the Warth emc gland does not require the sheathing to be terminated within the gland itself, so the shielding braid can be continued into the case unhindered giving protection up to point where the data cable terminates on the circuitry or enters a motor control unit for example.
