Overall copper braid in both screening families.
Individual aluminium tape pair screens in the double screened design.
Choose the FRL model family, pair count and conductor area. Compare the matching dimensional table for cable routing space, diameter and weight.
The nominal voltage is 300/500V and the impedance is 120 ohms ±15%.
The double screened construction adds individual aluminium tape pair screens to the overall copper braid used in both designs.
Cross-linked foam PE insulation is combined with cross-linked EVA rubber type EM 104 or an equivalent sheath.
0.22, 0.5, 0.75 and 1 mm² sizes are shown, each with 1, 2 and 4 pair versions.
FRL-MVB-02Y(ST)CH-IOS-XPYS identifies the double screened family; FRL-MVB-02YCH-OS-XPYS identifies the single screened family.
