I bought 100ft of cat5e ethernet cable. I will not be using it for ethernet but my own circuits that I built. 3 lines will be used for leds, the other 4 will send parallel data to a logic circuit. 1 for gnd. The max current I'll have going through the lines will be around 40mA@ 5.2v. Is this in the safe range for this type of cable?What is the max current and voltage these wires can handle?
As an electrician, your project should be fine. Though not built for power, the insulation of cat5 can deal with 50v at an amp or two.
Cat 6 is particularly speedier and has better sign to noise (only particularly), besides the shown fact that I doubt the cable is your situation! in the journey that your community is sluggish, it quite is better than in all danger to be in a swap, router, computing gadget, community card, and so on than interior the cable! Cables usually will purely influence the gadget it is linked to them no longer the full community!
No problem at all, CAT5e is good for about an amp. It is used at 48v in 'Power-over-Ethernet' applications (PoE). I would suggest that if you can, put your voltage regulator (if you've got one!) at the far end (the end to be powered) of the CAT5e run - you will be affected less by cable impedances and fluctaution caused by differing return currents (from LED's). Also, lower the impedance of your logic signals (perhaps use some 4K7 resistors on the logic inputs) to reduce the risk from static or induced currents/voltages.
