Cables

The yellow profiled cable has become

synonymous with AS-Interface. It has a

geometrically defined cross-section and

simultaneously transmits data and auxil-

iary power to the sensors. Additional aux-

iliary power is required for the actuators

(aux. voltage, e.g. 24 V DC). Different

coloured profiled cables have been spec-

ified utilising the same installation tech-

nology. A black profiled cable is therefore

used for 24 V DC auxiliary voltages.

The core insulation usually consists of a

rubber mixture (EPDM). For applications

where demands are greater, e.g. resis-

tance to chemicals, profiled TPE (ther-

moplastic elastomer) or PUR (poly-

urethane) cables are available. However,

round two-wire cables without PE con-

ductor can also be used as the trans-

mission cable.

The transmission technology obviates

the need for cable shielding.
