Shielded cables
The following factors decisively determine the effect of the shielded cables:
Good shield connection
ƒ
–
Ensure a contact surface as large as possible
Low shield resistance
ƒ
–
Only use shields with tin−plated or nickel−plated copper braids (shields
with steel braids cannot be used).
High overlap rate of the braid
ƒ
–
At least 70 ... 80 % with 90° overlap angle
The ECSZS000X0B shield mounting kit includes a wire clamp and shield sheet.
