Patented 2:1 Technology for Hazardous Areas [Movie]

Use two sensors on just one line

The patented 2:1 technology from Pepperl+Fuchs provides potential savings of 50% on sensor wiring needs in hazardous areas.

Signals from NAMUR sensors can be transmitted in pairs to a control device via one line. Two digital sensors are wired anti-parallel to one strand pair that is connected to the switch amplifier.

System enhancements are another ideal application for the 2:1 technology, when additional signals are to be routed via existing and possibly at-capacity field wiring. Pepperl+Fuchs also provides this technology in sensor and valve interface modules for fieldbus applications.
