LI2Y(St)CY (TP)

Application

These data cables with twisted pairs are used for interference-free transmission of data and signals over longer distances. The high transmission rate are suitable for RS 422 and RS 485 interfaces. This cable forms an integral part of supervisory control and data acquisition (SCADA) systems. These cables are suitable for fixed installations as well as for flexing applications, for free movement without forced motion and without tensile stress in dry and moist environment.

Properties

PVC self-extinguishing and flame retardant according to EN 60332-1-2. The twisted-pair lay-up prevents electrical unbalances within the cable and this thus effectively suppresses cross-talking effects.
