Interface Cable for Computer
UL 4325 Cables for RS-4325, RS-449
Operating temperature 80°C, Operating voltage 30V
Application
For RS-422A, RS-449 equipment connection
Features
- Conductor size AWG24 is suitable for long- and medium-distance transmission, and AWG28 is suitable for medium-distance transmission.
- The braided shield and polyaluminum tape collectively double shielded to provide excellent shield shielding properties.
