    Sensors with output type „R“ are designed for interconnect to intrinsically safe supply units. In case of strong ambient electromagnetic interference, paralleling of conductors with power distribu- tion, or for the distribution to distance over 30 m, we recommend to use shielded cable. © Dinel, s.r.o.
