Cross-linked EVA rubber sheath, type EM 104 or equivalent.
Select the single or double screened family, number of pairs and conductor area. Use the corresponding BRAIL model table for overall diameter and weight.
The single screened cable has an overall copper braid. The double screened cable adds individual aluminium tape screens around the pairs.
The insulation is cross-linked foam PE.
Cross-linked EVA rubber type EM 104 or equivalent, in accordance with EN 50264-1.
1, 2 and 4 pairs are listed in 0.22, 0.5, 0.75 and 1 mm² conductor sizes.
BRAIL MVB-02Y(ST)CH-IOS-XPYS lists the double screened design; BRAIL MVB-02YCH-OS-XPYS lists the single screened design.
