Valve connector cables with free-wheeling diode as the protective circuit

Phoenix Contact now also offers protective circuits with free-wheeling diode for valve connector cables for 24 V DC solenoid valves. These cables are primarily used in machine and system engineering.


What exactly does a free-wheeling diode do?

Free-wheeling diodes quickly and completely discharge the energy that occurs on a switching operation and thus prevent arcs from occurring at the relay contacts connected upstream of the solenoid valves.

This can increase the service life of relays by factor 5 to 10.

The advantages

For assembled valve connector cables, you can now choose between protective circuits with Zener diode, varistor, and free-wheeling diode.

The housing is molded with the same type of black transparent TPU material as used in existing types and together with the high-contrast status LEDs it also offers maximum protection against a wide range of different types of oil, water, and other media.


Extremely rugged housing

The housing is molded with the same type of black transparent TPU material as used in existing types and together with the high-contrast status LEDs it also offers maximum protection against a wide range of different types of oil, water, and other media.

In addition to the halogen-free 0.5 mm² PUR cable, another special feature is the functional design with integrated seal. Further cable types with a cable cross section of 0.75 mm², other sheath materials and colors, and additional protective circuits for other voltage ranges are available on request.
