Application
UNITRONIC
BUS PB ROBUST is a data cable for a field bus with 150 Ω nominal impedance.
It is dedicated for fixed installations in dry, damp and wet rooms. In consideration of the temperature range it can
be used outside. At room temperature it is increased resistant against acids, caustics solutions and certain oils,
greases, waxes of vegetable, animal, mineral and/or synthetic basis.
UNITRONIC
BUS PB ROBUST can be used especially as a BUS cable in machine tool manufactory and plant
engineering, in power stations, in heating and air conditioning installations, agriculture, food-, pharmaceutical-
and cosmetically industry, in composting- and sewage plants, by the production of textile fibre, of water
based purification plants by industrial and private use.
