Note :
1 : Number of twist is not specified. However, it shall satisfy the electrical specifications such as characteristic impedance,
attenuation, etc. (Example : More than 40times/m)
2 : Cross talk attenuation is applied when the twisted cable has 2 pairs (2P)
3 : Material is not specified. However, it shall be selected by considering the operating environment (Temperature,
Humidity), and the regional regulation by the environmental condition (ROHS Directive, etc.)
4 : Mechanical specification is not specified. However, it shall be selected by considering the operating environment.
5 : Never bundle transmission cable with power supply cable.
