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.
