Application fit

Is JE-LiYCY right for your machine?

JE-LiYCY (`JE-LiYCY...Bd`) bridges the gap between solid-wire building cables (`J-Y(st)Y`) and fine-wire machine cables (`LiYCY (TP)`): its 7-wire `0.5 mm²` conductors clamp reliably in marshalling cabinet screw/spring terminals, while 4-pair unit bundles (`Bd`) and a `2.0 kV`-tested tinned-copper braid suit DCS/PLC process plants.

Fixed installation

Suitable

DCS/PLC marshalling cabinets, process plant field junction boxes, 4–20 mA / HART loops and Ex-i barriers.

VFD inverter to AC motor screened feeder

Suitable

High-coverage tinned-copper braid screen ('C', tested at 2000 V core/screen) suppresses heavy industrial switching noise.

Trailing & towing

With conditions

7-wire stranded conductors tolerate cabinet door flexing and vibration, but are not for mobile trailing.

Use LiYCY (TP)

Energy chain / drag chain

Not suitable

Not intended for dynamic drag chains.

Decode the German designation JE-LiYCY...Bd.

'JE' = Industrial Electronic installation cable ('Installationskabel für Industrieelektronik'); 'Li' = 7-wire stranded copper conductor (7×0.30 mm = 0.5 mm²); first 'Y' = PVC core insulation; 'C' = overall tinned-copper wire braid screen; second 'Y' = PVC outer sheath; 'Bd' = 4-pair unit-bundle stranding ('Bündelverseilung').

How does JE-LiYCY differ from J-Y(st)Y and LiYCY (TP)?

J-Y(st)Y uses solid 0.6/0.8 mm copper wires and a thin aluminium foil screen ('(St)') for building telecoms. LiYCY (TP) uses Class 5 fine-stranded wires in concentric layers for machine tools. JE-LiYCY uses 7-wire 0.5 mm² conductors cabled into 4-pair unit bundles ('Bd') with a heavy tinned-copper wire braid ('C') tested at 2000 V AC between cores and screen specifically for DCS/PLC marshalling in chemical and power plants.

What is the pair colour code inside each 4-pair bundle of JE-LiYCY...Bd?

Under DIN VDE 0815 for industrial electronic ('JE') cables: Pair 1 = blue + red, Pair 2 = grey + yellow, Pair 3 = green + brown, and Pair 4 = white + black. Each bundle is identified by ring markings.

Why is JE-LiYCY available with a sky-blue (RAL 5015) outer sheath?

In chemical, petrochemical and oil & gas plants, a sky-blue (RAL 5015) outer sheath designates 'EB' ('Eigensicher') intrinsically safe Ex-i instrumentation circuits in accordance with EN 60079-14.
