They are often used to detect if a storage device, such as an MFSU, has reached capacity, or if a Nuclear Reactor has finished a cycle. They are able to handle EU Packets up to 512 with energy loss of 0.5 EU per block, making them inefficient for long distances.
- If placed directly on an MFE's output face, the detector cable will emit HV current even though this is not normally possible with an MFE, destroying machines unable to accept the current.
- The use of these is great if you need a compact solution to keep your advanced machines (Induction Furnace, Singularity Compressor, etc.) running. The only downside is you will have no way to turn them off other than removing the cable, but if you're building these machines in the first place that usually isnt an issue.
