Shielded cables
The following factors decisively determine the effect of the shielded cables:

ƒ

Good shield connection

Ensure a contact surface as large as possible

ƒ

Low shield resistance

Only use shields with tin-plated or nickel-plated copper braids (shields
with steel braids cannot be used).

ƒ

High overlap rate of the braid

At least 70 ... 80 % with 90° overlap angle

The ECSZS000X0B shield mounting kit includes a wire clamp and shield sheet.
