Specialist electrical connector lubricants do not cause increased circuit resistance

One of the most common misconceptions we come across is that some electrical engineers think that using one of our specialist connector lubricants will cause extra circuit resistance/circuit impedance across a connector or circuit – this is not correct! As a number of customers ask this same question about possible extra circuit resistance when using a connector lubricant/grease, we thought that a video demonstration would illustrate that engineers need not have any concerns about increased circuit impedance when using our specially formulated connector lubricants.

Our synthetic connector grease is specially formulated to ensure that no extra contact resistance results from applying the lubricant between two contact surfaces. Yes the grease will sit between the two metal contact surfaces but you must think of the contact in microscopic terms; the two contact surfaces that are mated to form an electro mechanical connection appear to have a smooth surface to the naked eye but when viewed under a microscope, the surfaces (or surface topography) will be rough, jagged, like a mountain range. The current (or data) will pass between the two contact surfaces where the mountain peaks touch (some refer to as asperities), while the grease will sit in the valleys/gaps of the mountain range and so microscopically, the the grease is not actually getting in the way.
