SD220/SD230 PROBE WIRING RECOMMENDATIONS
For maximum noise immunity, splice or terminate cables only when absolutely necessary. Where
extension is necessary, use Belden 8761 or equivalent shielded twisted pair cable. The SD22x fami
ly
of products is designed to provide high common mode noise rejection. Common mode rejection is
realized most effectively with twisted pair cabling.
3. Maintain independent shields
4. Position shield terminals between
transmitter and receiver signal terminals
1. Minimize unshielded lengths.
2. Twist signal wires together where
unshielded.
