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.
