The FOGRod comes in three lengths – 7.5 ft, 5ft and 3ft – each type has 10 contacts (separated by 9″, 6″ and 3″ respectively). If you need a 10ft or 15ft Fogrod we supply 2x 5ft or 2x 7.5ft FOGRods (and 1 LIT). Each FOGRod has the option of two cable lengths – 50 ft or 100 ft and we manufacture custom units with longer cables to order. The FOGRod also comes with a 10-year warranty.
We also have 3-contact and single contact Fogrods, with a failsafe wire (for testing cable integrity). Contact us for more information.
If you don’t already have D.C. power in the panel (e.g. powering a PLC or telemetry unit) you will need a D.C. power supply.
