Unitronic® LiYCY (TP)
(Farnell: Overall screened twisted pair data cables)
Application
UNITRONIC® LiYCY (TP) is a screened, paired, flexible cable for control and data transmissions, for weak- current
applications. The fine wired conductor (7-wired for 0.34mm2) and the robust ductile outer sheath gives the cable
strength as well as high flexibility. By the pair twisting the electric circuits are well decoupled and with the screen of a
tinned copper braiding the cabel is protected against external electrical influences.
The cable is intended for static laying and flexible use in dry and damp interiors. Design and electrical characteristics
similar to VDE 0812.
